[Other] Show HN: Open-sourcing our text-to-CAD app Hey HN! I&#x27;m Zach from Adam (<a href="https:&#x2F;&#x2F;adam.new&#x2F;">https:&#x2F;&#x2F;adam.new&#x2F;</a>). We’re building an AI co-pilot for mechanical CAD software.<p>As part of our broader research, we built a browser-based Text-to-CAD app (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206</a>) and are now open sourcing it. This is a React SPA with a Supabase backend.<p>What it does:<p>* Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references<p>* Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension tweaking<p>* Exports as .STL or .SCAD<p>Under the hood:<p>* Separate agents for conversation and code generation; simple parameter tweaks bypass AI entirely using deterministic regex-based updates<p>* Runs fully in-browser by compiling OpenSCAD to WebAssembly and integrating Three.js with React Three Fiber for 3D rendering<p>* Supports BOSL, BOSL2, MCAD libraries and custom font support (Geist) for text in models<p>We’ve seen many developers trying to replicate this kind of functionality, so we’re releasing this to give the community a solid foundation to build on.<p>Future improvements:<p>* Expand geometry support - Move beyond CSG primitives to support curved surfaces, fillets, lofts, and constraint-driven modeling through CadQuery&#x2F;Build123D<p>* Better spatial context - UI for face&#x2F;edge selection and viewport image integration to give LLMs spatial understanding<p>* Enhanced capabilities - RAG on documentation and integration with more OpenSCAD libraries for features like proper threading<p>You can clone the repo and run it locally! Contributions are welcome, and we’ll keep merging PRs as they come in.

[Database] Show HN: Text2SQL with a Graph Semantic Layer Built QueryWeaver, an open-source text2SQL tool that uses a graph to create a semantic layer on top of your existing databases. When you ask &quot;show me customers who bought product X in a certain ‘REGION’ over the last Y period of time,&quot; it knows which tables to join and how. When you follow up with &quot;just the ones from Europe,&quot; it remembers what you were talking about.<p>Instead of feeding the model a list of tables and columns, we feed it a graph that understands what a customer is, how it connects to orders, which products belong to a campaign, and what &quot;active user&quot; actually means in your business context. We used FalkorDB for the graph part because it handles relationship mapping better than cramming table schemas into prompts. Graphiti tracks the conversation so follow-ups actually work. Final notes: Your data stays in your databases. We read from existing schemas, never migrate data. Standard SQL outputs you can run anywhere. We&#x27;ve built an MCP and you can generate an API key to take it for a spin. Please, tell us how it’s working out for you!

[CLI Tool] Show HN: I built a deep research tool for local file system I was experimenting with building a local dataset generator with deep research workflow a while back and that got me thinking. what if the same workflow could run on my own files instead of the internet. being able to query pdfs, docs or notes and get back a structured report sounded useful.<p>so I made a small terminal tool that does exactly that. I point it to local files like pdf, docx, txt or jpg. it extracts the text, splits it into chunks, runs semantic search, builds a structure from my query, and then writes out a markdown report section by section.<p>it feels like having a lightweight research assistant for my local file system. I have been trying it on papers, long reports and even scanned files and it already works better than I expected. repo - <a href="https:&#x2F;&#x2F;github.com&#x2F;Datalore-ai&#x2F;deepdoc" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Datalore-ai&#x2F;deepdoc</a><p>Currently citations are not implemented yet since this version was mainly to test the concept, I will be adding them soon and expand it further if you guys find it interesting.

So I decided to create a new one.

[Other] Show HN: Zyg – Stop Writing Status Updates Hi HN, I’m Tobi. For a couple of hours over the past few days I’ve been hacking on something to fix a pain point in my dev workflow: writing status updates.<p>Progress is invisible by default. GitHub, Linear, Jira all track tickets and code, but they don’t do a good job of capturing the narrative between “ticket started” and “ticket done.”<p>You start working on a feature, your PM asks “how’s it going?”, and even though you know exactly how it’s going - because you’ve been committing and making progress - you still struggle to answer. That usually means breaking your flow to piece together an update, or just saying “it’s going fine.” You could point them to the commits, but tbj they probably don’t want to wade through diffs.<p>To solve this I built Zyg [pronounced zeig]. It tries to turn commits into human-readable progress updates. It’s a lightweight CLI + dashboard that wraps `git commit`. Running `zyg` will generate a detailed commit message from your changes, produce a project update from that commit or a set of commits you choose, and notify any stakeholders who are subscribed. If you’d rather not share updates automatically, you can just copy the generated summary and drop it in Slack or email.<p>Zyg is free for September thanks to an API credit grant from Anthropic. After that I’ll figure out pricing, but you can also plug in your own key and keep using it for free. It’s still rough around the edges, but I’d appreciate you giving it a spin.

[Other] Show HN: StripeMeter – Open-Source Usage Metering for Stripe Billing We built StripeMeter, an open-source usage metering platform that plugs directly into Stripe. It solves the classic SaaS pain of “why is my bill higher than expected?” by giving both developers and customers real-time usage tracking with live cost projections. Why it matters:<p>- Transparency: Customers see exactly what Stripe will bill them (within 0.5% parity).<p>- Exactly-once guarantee: No double billing, ever.<p>- Fast &amp; scalable: Sub-minute freshness with Redis + Postgres counters.<p>We’d love feedback from SaaS builders, especially if you’ve struggled with Stripe’s metered billing. Does this solve a real pain for you? What would you need before trusting it in production?

[Other] Show HN: Fine-tuned Llama 3.2 3B to match 70B models for local transcripts I wrote a small local tool to transcribe audio notes (Whisper&#x2F;Parakeet). Code: <a href="https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;lazy-notes" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;lazy-notes</a><p>I wanted to process raw transcripts locally without OpenRouter. Llama 3.2 3B with a prompt was decent but incomplete, so I tried SFT. I fine-tuned Llama 3.2 3B to clean&#x2F;analyze dictation and emit structured JSON (title, tags, entities, dates, actions).<p>Data: 13 real memos → Kimi K2 gold JSON → ~40k synthetic + gold; keys canonicalized. Chutes.ai (5k req&#x2F;day).<p>Training: RTX 4090 24GB, ~4h, LoRA (r=128, α=128, dropout=0.05), max seq 2048, bs=16, lr=5e-5, cosine, Unsloth. On 2070 Super 8GB it was ~8h.<p>Inference: merged to GGUF, Q4_K_M (llama.cpp), runs in LM Studio.<p>Evals (100-sample, scored by GLM 4.5 FP8): overall 5.35 (base 3B) → 8.55 (fine-tuned); completeness 4.12 → 7.62; factual 5.24 → 8.57.<p>Head-to-head (10 samples): ~8.40 vs Hermes-70B 8.18, Mistral-Small-24B 7.90, Gemma-3-12B 7.76, Qwen3-14B 7.62. Teacher Kimi K2 ~8.82.<p>Why: task specialization + JSON canonicalization reduces variance; the model learns the exact structure&#x2F;fields.<p>Lessons: train on completions only; synthetic is fine for narrow tasks; Llama is straightforward to train.

[CLI Tool] Show HN: My first Go project, a useless animated bunny sign for your terminal Hi HN, I wanted to share my very first (insignificant) project written in Go: a little CLI tool that displays messages with an animated bunny holding a sign.<p>I wanted to learn Go and needed a small, fun project to get my hands dirty with the language and the process of building and distributing a CLI. I&#x27;ve built a similar tool in JavaScript before so I thought porting it would be a great learning exercise.<p>This was a dive into Go&#x27;s basics for me, from package structure and CLI flag parsing to building binaries for different platforms (never did that on my JS projects).<p>I&#x27;m starting to understand why Go is so praised: it&#x27;s standard library is huge compared with other languages. One thing that really impressed me was the idea (at some point of this journey) to develop a functionality by myself (where in the javascript original project I choose to use an external library), here with the opportunities that std lib was giving me I thought &quot;why don&#x27;t try to create the function by miself?&quot; and it worked! In the Js version I used the nodejs &quot;log-update&quot;, here I write a dedicated pkg.<p>I know it&#x27;s a bit silly, but I could see it being used to add some fun to build scripts or idk highlight important log messages, or just make a colleague smile. It&#x27;s easy to install if you have Go set up:<p><pre><code> go install github.com&#x2F;fsgreco&#x2F;go-bunny-sign&#x2F;cmd&#x2F;bunnysign@latest </code></pre> Since I&#x27;m new to Go, I would genuinely appreciate any feedback on the code, project structure, or Go best practices. The README also lists my planned next steps, like adding tests and setting up CI better.<p>Thanks for taking a look!

[Other] Show HN: Q.js – Smaller than React/Vue, yet more powerful (40KB gzipped) Q.js is a lightweight JS framework that I recently distilled from our in-house Qbix platform that I’ve been building since 2011. It powers many of our social apps, which have all the features of Facebook, LinkedIn, X, etc.<p>We’re not a big company like Google or Meta, so we never released it publicly. Now I’d like to, and thought it would be a good idea to post it on HN and gather some feedback.<p>Q.minimal.js was designed to be dropped into any website. It lazy-loads all your components only as they are needed and appear on the screen. The minimal file is meant as a starting point for developers, and if you later want more features from the Qbix platform, you can simply swap it out for the larger Q.js file instead.<p>Here are some advantages of Q.minimal.js compared to React, Angular, Vue, or whatever you might be using now:<p>40KB gzipped, smaller than React (without ReactDOM), smaller than Vue runtime, far smaller than Angular<p>No build step, just drop it in; works with plain .html &lt;template&gt; files or with JS&#x2F;Handlebars templates<p>Components &amp; tools, like React components or Vue directives, but attachable as behaviors to any DOM element<p>Faster rendering with requestAnimationFrame and .rendering(), no giant virtual DOM reconciliation<p>Built-in power: batching, caching, lazyloading, routing, slot-based page activation, all included in core<p>Universal dev model: designers can use pure HTML, developers can use JS, both work interchangeably<p>Incremental: drop it into an existing site without rewriting or compiling anything<p>If you have a free hour, give it a try! Play around with it, and let me know what you think. It&#x27;s 100% free and open source under MIT license and I&#x27;m looking to polish up any rough edges before letting developers know about it.

It should work with Codex or any other CLI-based agent!<p>I have a long term idea where the models are all local and then the tool is privacy preserving because it&#x27;s easy to remove PII from text, but I&#x27;d definitely not recommend using this for anything important just yet. You&#x27;ll need a Gemini key until I (or someone else) figure out how to distill a local version out of that part of the pipeline.<p>Github link: <a href="https:&#x2F;&#x2F;github.com&#x2F;moonshinelabs-ai&#x2F;skipper-tool" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;moonshinelabs-ai&#x2F;skipper-tool</a>

[Other] Show HN: I made a mini site to see timezone shifts Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so.<p>Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you&#x27;re coming to the wrong place, but feel free to yoink the code.<p>Its just one fat index.html file. Served off my VPS via caddy file server. No dependencies or build steps. See the code in the github link below.<p>All the CSS is &quot;vibe coded&quot;, I think it looks pretty cool.<p>As an aside, I love that AI has made it so easy to spit out sites like this. My personal site is filled with subdomains like this one with little random tools which I occasionally use.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;rupert648&#x2F;timezone-fuckery&#x2F;blob&#x2F;main&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rupert648&#x2F;timezone-fuckery&#x2F;blob&#x2F;main&#x2F;inde...</a>

[Other] Show HN: Sourcerer – MCP for semantic code search that reduces token waste I built this because I got tired of watching Claude Code read through massive files just to find a few functions. Sourcerer lets AI agents search code semantically and grab exactly the code chunks they need instead of burning tokens on whole files.<p>It uses tree-sitter to parse your codebase and creates a searchable index. So instead of &quot;read auth.py (538 lines)&quot;, an agent can search for &quot;user authentication logic&quot; and get back just the relevant functions.<p>Demo: <a href="https:&#x2F;&#x2F;asciinema.org&#x2F;a&#x2F;736638" rel="nofollow">https:&#x2F;&#x2F;asciinema.org&#x2F;a&#x2F;736638</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;st3v3nmw&#x2F;sourcerer-mcp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;st3v3nmw&#x2F;sourcerer-mcp</a>

Instant visuals where developers live * Zero setup. Download binary or use &quot;go run&quot;, and dashboards appear * Great for sysadmins, devs, ops, data hackers working in terminal-first workflows<p>What I learned building it: Automating a clean layout via algorithm beats manual dashboard design for fast insights. Generating widgets in terminal forces clarity - no fluff, just signal.<p>Looking for feedback on:<p>* Performance with massive datasets (&gt;100k rows) * UX: readability, layout transitions, color themes * Widget ideas: real-time alerts, sparkline ring charts, CLI-friendly drill-downs<p>Live on GitHub.

[DevOps] Show HN: Kanto.ai – The soc2 ready infra agent Hey HN,<p>I am launching kanto.ai and looking for early beta users.<p>This came out of my own experience. I was responsible for building and maintaining SOC-2 compliance for a Kubernetes application in GCP. The GCP Cloud Foundation Blueprints are a solid starting point, but they are difficult to set up and even harder to keep updated as requirements, policies, and cloud services evolve. Many aspects required for Soc2 are also not provided out of the box.<p>kanto.ai is a GitHub bot that bootstraps an enterprise-grade, multi-repo, git-ops first GCP deployment and automates ongoing maintenance. It watches GitHub issues and generates Terraform pull requests with best practices built in. Under the hood it uses GCP’s Cloud Foundation Toolkit modules for projects, networking, org policies, IAM, and more. The goal is to keep infrastructure SOC-2 ready out of the box.<p>Right now it is early with a landing page and working prototype. I would love feedback from anyone who has dealt with SOC-2, Kubernetes, or the Foundation Blueprints in GCP.<p>Does this solve a real pain you have felt? What blockers did you run into with SOC-2 in GCP? If you used the GCP Cloud Foundation Toolkit, what worked and what did not?<p>Thanks.

[Other] Show HN: Sosumi.ai – Convert Apple Developer docs to AI-readable Markdown I got tired of Claude hallucinating Swift APIs. It does a good job at Python and TypeScript, but ask it about SwiftUI and it&#x27;s basically guessing.<p>The problem? Apple&#x27;s docs are JavaScript-rendered, so when you paste URLs into AI tools, they just see a blank page. Copy-pasting works but... c&#x27;mon.<p>So I built something that converts Apple Developer docs to clean markdown. Just swap developer.apple.com with sosumi.ai in any Apple docs URL and you get AI-readable content.<p>For example:<p>- Before: <a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;documentation&#x2F;swift&#x2F;double" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;documentation&#x2F;swift&#x2F;double</a><p>- After: <a href="https:&#x2F;&#x2F;sosumi.ai&#x2F;documentation&#x2F;swift&#x2F;double" rel="nofollow">https:&#x2F;&#x2F;sosumi.ai&#x2F;documentation&#x2F;swift&#x2F;double</a><p>The site itself is a small Hono app running on Cloudflare Workers. Apple&#x27;s docs are actually available as structured data, but Apple doesn&#x27;t make it obvious how to get it. So what this does is map the URLs, fetch the original JSON, and render as Markdown.<p>It also provides an MCP interface that includes a tool to search the Apple developer website, which is helpful.<p>Anyway, please give this a try and let me know what you think!

Your text never leaves your computer during checking.<p>Here’s a 2-minute overview: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;baf501ee6cf14a919a7384128246ed67" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;baf501ee6cf14a919a7384128246ed67</a><p>Because it uses an LLM, it catches more than spelling and grammar. For example, it can correct some wrong statements like “The first US president was Benjamin Franklin.”<p>Grammit also includes an in-page writing assistant that can rephrase or draft new text. It also uses the local LLM.<p>We used many new web features to build this, such as:<p>- Chrome’s new Prompt API to talk to the local model.<p>- Anchor Positioning API to place the UI with minimal impact on the DOM.<p>- CSS Custom Highlights API for inline error marking.<p>- The new CSS sign() function to create CSS-driven layout with discontinuities.<p>Part of the fun of being early adopters of bleeding edge tech is we’re discovering new Chrome bugs (e.g., <a href="https:&#x2F;&#x2F;issues.chromium.org&#x2F;issues&#x2F;428354426" rel="nofollow">https:&#x2F;&#x2F;issues.chromium.org&#x2F;issues&#x2F;428354426</a>, <a href="https:&#x2F;&#x2F;issues.chromium.org&#x2F;issues&#x2F;428039224" rel="nofollow">https:&#x2F;&#x2F;issues.chromium.org&#x2F;issues&#x2F;428039224</a>).<p>I’d love your feedback on:<p>- Where the UX feels rough<p>- What do you think of the corrections and suggestions<p>Happy to answer questions about the tech or the Prompt API.

[Monitoring/Observability] Show HN: MCPcat – A free open-source library for MCP server monitoring Hey everyone!<p>We&#x27;ve been working with several MCP server maintainers and we noticed some difficulties getting drop-in logging and identity attribution working out of the box with existing vendors. A couple of challenges we hoped to solve were: - Baseline piping of tool calls to traditional vendors - How to tie tool calls to a “user session” - Understanding the context behind tool calls made by agents<p>So we built something. :) The MCPcat library is completely free to use, MIT licensed, and provides a one-line solution for adding logging and observability to any vendor that supports OpenTelemetry. We added custom support for Datadog and Sentry because we personally use those vendors, but we’re happy to add more if there’s interest.<p>Here’s how it works:<p><pre><code> mcpcat.track(serverObject, {...options…}) </code></pre> This initializes a series of listeners that: 1. Categorize events within the same working session 2. Publish those events directly to your third-party data provider<p>Optionally, you can redact sensitive data. The data never touches our servers (unless you opt in to additional contextual analysis, which I mention below).<p>Some teams might also want a better understanding of “what use cases are people finding with my MCP server.” For that, we provide a separate dashboard that visualizes the user journey in more detail (free for a high baseline of monthly usage and always free for open source projects).<p>We have two SDKs so far: Python SDK: &lt;<a href="https:&#x2F;&#x2F;github.com&#x2F;MCPCat&#x2F;mcpcat-python-sdk" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;MCPCat&#x2F;mcpcat-python-sdk</a>&gt; TypeScript SDK: &lt;<a href="https:&#x2F;&#x2F;github.com&#x2F;MCPCat&#x2F;mcpcat-typescript-sdk" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;MCPCat&#x2F;mcpcat-typescript-sdk</a>&gt;<p>Other SDKs are on the way!

[API/SDK] Show HN: SwiftAI – open-source library to easily build LLM features on iOS/macOS We built SwiftAI, an open-source Swift library that lets you use Apple’s on-device LLMs when available (Apple opened access in June), and fall back to a cloud model when they aren’t available — all without duplicating code.<p>SwiftAI gives you: - A single, model-agnostic API - An agent&#x2F;tool loop - Strongly-typed structured outputs - Optional chat state<p>Backstory: We started experimenting with Apple’s local models because they’re free (no API calls), private, and work offline. The problem: not all devices support them (older iPhones, Apple Intelligence disabled, low battery, etc.). That meant writing two codepaths — one for local, one for cloud — and scattering branching logic across the app. SwiftAI centralizes that decision. Your feature code stays the same whether you’re on-device or cloud.<p>Example<p><pre><code> import SwiftAI let llm: any LLM = SystemLLM.ifAvailable ?? OpenaiLLM(model: &quot;gpt-5-mini&quot;, apiKey: &quot;&lt;key&gt;&quot;) let response = try await llm.reply(to: &quot;Write a haiku about Hacker News&quot;) print(response.content) </code></pre> It&#x27;s open source — we&#x27;d love for you to try it, break it, and help shape the roadmap.

[Other] Show HN: I built AI that turns 4 hours of financial analysis into 30 seconds I built Duebase AI to solve a problem I kept running into in fintech - analyzing UK company financial health takes forever. The process usually goes: download PDFs from Companies House → manually extract data to spreadsheets → calculate ratios → interpret trends. Takes 3-4 hours per company and requires serious financial expertise. The technical challenge: Companies House filings are messy. Inconsistent formats, complex accounting structures, missing data, and you need to understand UK accounting standards to make sense of it all. My approach:<p>Parse 15M+ UK company records from Companies House API Built ML models to extract and normalize financial data from varied filing formats Created scoring algorithms that weight liquidity, profitability, leverage, and growth trends Generate 1-5 health scores with explanations in plain English<p>What it does:<p>Instant financial analysis of any UK company (30 seconds vs 4 hours) Real-time monitoring with alerts for new filings&#x2F;director changes Risk detection that catches declining trends early No financial background needed to understand results<p>The hardest part was handling the data inconsistencies - UK companies file in different formats, use various accounting frameworks, and often have incomplete information. Had to build a lot of data cleaning and normalization logic. Currently focused on the UK market since I know the regulatory landscape well, but the approach could work for other countries with similar public filing systems.

[Other] Show HN: Regolith – Regex library that prevents ReDoS CVEs in TypeScript I wanted a safer alternative to RegExp for TypeScript that uses a linear-time engine, so I built Regolith.<p>Why: Many CVEs happen because TypeScript libraries are vulnerable to Regular Expression Denial of Service attacks. I learned about this problem while doing undergraduate research and found that languages like Rust have built-in protection but languages like JavaScript, TypeScript, and Python do not. This library attempts to mitigate these vulnerabilities for TypeScript and JavaScript.<p>How: Regolith uses Rust&#x27;s Regex library under the hood to prevent ReDoS attacks. The Rust Regex library implements a linear-time Regex engine that guarantees linear complexity for execution. A ReDoS attack occurs when a malicious input is provided that causes a normal Regex engine to check for a matching string in too many overlapping configurations. This causes the engine to take an extremely long time to compute the Regex, which could cause latency or downtime for a service. By designing the engine to take at most a linear amount of time, we can prevent these attacks at the library level and have software inherit these safety properties.<p>I&#x27;m really fascinated by making programming languages safer and I would love to hear any feedback on how to improve this project.

[IDE/Editor] Show HN: First background agents in Jetbrains IDEs [video] TLDR: made the first background coding agent that has an isolated workspace and runs locally<p>Howdy - I’m Kevin, co-founder of Firebender, and we built the first background coding agent in android studio &#x2F; Jetbrains!<p>Why not just use Cursor background agents or OpenAI Codex?<p>Both of these require setting up a cloud container and cloning your existing developer environment, and maintaining it. Then when you want to iterate on changes as AI inevitably makes a mistake, you either throw away the work, or have to pull down the branch and clean it up. This feels really clunky. With Firebender, background agents run locally in a lightweight git worktree&#x2F;IDE tab. This means when the agent is done, you can easily clean up the changes and run code with a few clicks.<p>Under the hood, the agent behaves similarly to claude code (didn’t want to reinvent the wheel), but also leverages all of the hooks into IntelliJ sdk like go-to-definition, find usages, auto-imports for accuracy, and it gives a cleaner visual UI for reviewing changes and merging them. You can use any frontier model like gpt-5&#x2F;sonnet-4 as the base.<p>We’ve had to do quite a bit of reverse engineering of the IntelliJ codebase to cleanly set up and manage the isolated environment, and I think you’ll appreciate the simple UX of hitting cmd+enter to run a background agent anywhere.<p>get started docs: <a href="https:&#x2F;&#x2F;docs.firebender.com&#x2F;get-started&#x2F;background-agents">https:&#x2F;&#x2F;docs.firebender.com&#x2F;get-started&#x2F;background-agents</a><p>download the plugin: <a href="https:&#x2F;&#x2F;firebender.com">https:&#x2F;&#x2F;firebender.com</a><p>Would love to get your feedback to help us improve the tool for you!

[Code Quality] Show HN: Framework to create linters for Python, YAML, TOML, JSON Hi, this is a Python framework I have created to make my life a little easier when creating custom linting rules.<p>Key features:<p>- Quick to use (~20 LOC to create a functioning linter&#x2F;checker)<p>- Works with different file formats (as in the description)<p>- Supports multiple ignore&#x2F;noqa directives (per-line ignores, range ignores, whole file, rules choice during runs)<p>- Single check can span all elements of the file or even all files<p>- Works directly with Python&#x27;s AST<p>- Tutorials and API reference to make users life easier<p>All in all seems to be quite functional for my private (yet) linters, so I decided to make it into a FOSS project.<p>Have fun, would love to hear your feedback and ideas regarding it!

[Other] Show HN: My OSS P2P file transfer tool for learning Next.js (as a C++ dev) Hey HN,<p>I&#x27;m a C++ algorithms engineer, and today I&#x27;d like to share my first full-stack web project: PrivyDrop.<p>This project was born from two ideas:<p>First, I wanted to solve a daily annoyance of mine: I needed a simple, AirDrop-like way to send text, links, or screenshots between my phone and PC. I tried many tools, but they either required me to sign up, had various limitations, or uploaded my data to their servers, which I was never comfortable with.<p>Second, this was a personal experiment. Last year, with all the talk about &quot;AI replacing programmers,&quot; I got curious. As a developer with no web background, I wanted to see how long it would take to learn full-stack development from scratch (an area I&#x27;m really interested in) and build a complete application, using AI as my primary coding partner and mentor.<p>PrivyDrop is the result of that learning and experiment.<p>It&#x27;s a peer-to-peer (P2P) file-sharing tool based on WebRTC. Its core principle is that *your data belongs only to you*: all files and text are transferred directly between your browser and the recipient&#x27;s, fully end-to-end encrypted, without ever passing through an intermediate server.<p>*Here are some of its key features:*<p>* Completely free and open-source, with no ads. * No sign-up or installation required—just open your browser. * Direct P2P connection for privacy, security, and speed. * No limits on file size or type. * Support for entire folder transfers. * Built-in resumable transfers.<p>The whole process has been a fantastic learning journey. I&#x27;m sharing it now in the hope that it can solve the same pain point for others. I&#x27;m really eager to hear any feedback, ideas, or even harsh criticism from the HN community!<p>* *Live Demo:* <a href="https:&#x2F;&#x2F;www.privydrop.app" rel="nofollow">https:&#x2F;&#x2F;www.privydrop.app</a> * *GitHub Repo:* <a href="https:&#x2F;&#x2F;github.com&#x2F;david-bai00&#x2F;PrivyDrop" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;david-bai00&#x2F;PrivyDrop</a><p>Thanks, everyone!

[API/SDK] Show HN: Mixing Deterministic Codegen with LLM Codegen for Client SDKs Hi HN, I’m Patrick. Elias, Kevin, and I are building Sideko (<a href="https:&#x2F;&#x2F;sideko.dev" rel="nofollow">https:&#x2F;&#x2F;sideko.dev</a>), a new type of code generator for building and maintaining API client SDKs from OpenAPI specs.<p>Our approach differs significantly from traditional SDK generators in that we use structured pattern matching queries to create and update the code. Other SDK generators use templates, which overwrite custom changes and produce code that looks machine generated.<p>We’ve mixed in LLM codegen by creating this workflow: Run deterministic codegen to establish the SDK structure. Let LLMs enhance specific components where adaptability adds value and include agent rules files that enforce consistency and correctness with type checking and integration tests against mock servers. The system will retain the LLM edits, while the rest of the SDK is automatically maintained by the deterministic generator (keeping it in sync with the API). LLMs can edit most the files (see python rules and typescript rules).<p>You can try it out from your terminal: Install: npm install -g @sideko&#x2F;cli Login: sideko login Initialize: sideko sdk init Prompt: “Add a new function that…”<p>Check out the repo for more details: <a href="https:&#x2F;&#x2F;github.com&#x2F;Sideko-Inc&#x2F;sideko" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sideko-Inc&#x2F;sideko</a> We’d love to hear your thoughts!

[Other] Show HN: Stagewise – frontend coding agent for real codebases Hey HN, we&#x27;re Glenn and Julian, and we&#x27;re building stagewise (<a href="https:&#x2F;&#x2F;stagewise.io">https:&#x2F;&#x2F;stagewise.io</a>), a frontend coding agent that inside your app’s dev mode and that makes changes in your local codebase.<p>We’re compatible with any framework and any component library. Think of it like a v0 of Lovable that works locally and with any existing codebase.<p>You can spawn the agent into locally running web apps in dev mode with `npx stagewise` from the project root. The agent lets you then click on HTML Elements in your app, enter prompts like &#x27;increase the height here&#x27; and will implement the changes in your source code.<p>Before stagewise, we were building a vertical SaaS for logistics from scratch and loved using prototyping tools like v0 or lovable to get to the first version. But when switching from v0&#x2F; lovable to Cursor for local development, we felt like the frontend magic was gone. So, we decided to build stagewise to bring that same magic to local development.<p>The first version of stagewise just forwarded a prompt with browser context to existing IDEs and agents (Cursor, Cline, ..) and went viral on X after we open sourced it. However, the APIs of existing coding agents were very limiting, so we figured that building our own agent would unlock the full potential of stagewise.<p>Since our last Show HN (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44798553">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44798553</a>), we launched a few very important features and changes: You now have a proprietary chat history with the agent, an undo button to revert changes, and we increased the amount of free credits AND reduced the pricing by 50%. We made a video about all these changes, showing you how stagewise works: <a href="https:&#x2F;&#x2F;x.com&#x2F;goetzejulian&#x2F;status&#x2F;1959835222712955140&#x2F;video&#x2F;1" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;goetzejulian&#x2F;status&#x2F;1959835222712955140&#x2F;video&#x2F;...</a>.<p>So far, we&#x27;ve seen great adoption from non-technical users who wanted to continue building their lovable prototype locally. We personally use the agent almost daily to make changes to our landing page and to build the UI of new features on our console (<a href="https:&#x2F;&#x2F;console.stagewise.io">https:&#x2F;&#x2F;console.stagewise.io</a>).<p>If you have an app running in dev mode, simply `cd` into the app directory and run `npx stagewise` - the agent should appear, ready to play with.<p>We&#x27;re very excited to hear your feedback!

[Other] Show HN: SecretMemoryLocker – File Encryption Without Static Passwords I built SecretMemoryLocker (<a href="https:&#x2F;&#x2F;secretmemorylocker.com" rel="nofollow">https:&#x2F;&#x2F;secretmemorylocker.com</a>), a file encryption tool that generates keys dynamically from your answers to personal questions instead of using a static master password. This makes offline brute-force attacks much more difficult. Think of it as a password manager that meets mnemonic seed recovery, but without storing any sensitive keys on disk.<p>Why? I kept losing master passwords and wanted a solution that wasn&#x27;t tied to a single point of failure. I also wanted to create a &quot;digital legacy&quot; that my family could access only under specific conditions. The core principle is knowledge-based encryption: the key only exists in memory when you provide the correct answers.<p>Status: * MVP is ready for Windows (.exe). * Linux and macOS support is planned. * UI is available in English, Spanish, and Ukrainian.<p>Key Features:<p>* No Static Secrets: No master password or seed phrase is ever stored. The key is reconstructed on the fly.<p>* Knowledge-Based Key Generation: The final encryption key is derived from a combination of your personal answers and file metadata.<p>* Offline Brute-Force Resistance: Uses MirageLoop, a decoy system that activates when incorrect answers are entered. Instead of decrypting real data, it generates an endless sequence of AI-created questions from a secure local database, creating an illusion of progress while keeping your real data untouched.<p>* Offline AI Generation Mode: Optional offline Q&amp;A generator (prototype).<p>How It Works (Simplified):<p>1) Files are packed into an AES-256 encrypted ZIP archive.<p>2) A JSON key file stores the questions in an encrypted chain. Each subsequent question is encrypted with a key derived from the previous correct answer and the file&#x27;s hash. This forces you to answer them sequentially.<p>3) The final encryption key for the ZIP file is derived by combining the hashes of all your correct answers. The key derivation formula looks like this:<p><pre><code> K_final = SHA256(H(answer1+file_hash) + H(answer2+file_hash) + ...) </code></pre> (Note: We are aware that a fast hash like SHA256 is not ideal for a KDF. We plan to migrate to Argon2 in a future release to further strengthen resistance against brute-force attacks.)<p>To encrypt, you provide a file. This creates two outputs: your_file.txt → your_file_SMLkey.json + your_file_SecretML.zip<p>To decrypt, you need both files and the correct answers.<p>Install &amp; Quick Start: Download the EXE from GitHub Releases (no dependencies needed):<p><a href="https:&#x2F;&#x2F;github.com&#x2F;SecretML&#x2F;SecretMemoryLocker&#x2F;releases" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;SecretML&#x2F;SecretMemoryLocker&#x2F;releases</a><p>Encrypt:<p><pre><code> SecretMemoryLocker.exe --encrypt &quot;C:\docs\important.pdf&quot; </code></pre> Decrypt:<p><pre><code> SecretMemoryLocker.exe --decrypt &quot;C:\docs\important_SMLkey.json&quot; </code></pre> I would love to get your feedback on the concept, the user experience, and any security assumptions I&#x27;ve made. Thanks!

[Database] Show HN: Base, an SQLite database editor for macOS I recently released v3 of Base, my SQLite editor for macOS.<p>The goal of this app is to provide a comfortable native GUI for SQLite, without it turning into a massive IDE-style app.<p>The coolest features are<p>- That it can handle full altering of tables, which is quite finicky to do manually with SQLite.<p>- It has a more detailed display of column constraints than most editors. Each constraint is shown as an icon if active, with full details available on clicking the icon.<p>This update also adds support for attaching databases, which is a bit fiddly with macOS sandboxing.<p>I&#x27;d love to hear any feedback or answer any questions.

[Other] Show HN: Async – Claude Code and Linear and GitHub PRs in One Opinionated Tool Hi, I’m Mikkel and I’m building Async, an open-sourced developer tool that combines AI coding with task management and code review.<p>What Async does:<p><pre><code> - Automatically researches coding tasks, asks clarifying questions, then executes code changes in the cloud - Breaks work into reviewable subtasks with stack diffs for easier code review - Handles the full workflow from issue to merged PR without leaving the app </code></pre> Demo here: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;98k42b8GF4s?si=Azf3FIWAbpsXxk3_" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;98k42b8GF4s?si=Azf3FIWAbpsXxk3_</a><p>I’ve been working as a developer for over a decade now. I’ve tried all sorts of AI tools out there including Cline, Cursor, Claude Code, Kiro and more. All are pretty amazing for bootstrapping new projects. But most of my work is iterating on existing codebases where I can&#x27;t break things, and that&#x27;s where the magic breaks down. None of these tools work well on mature codebases.<p>The problems I kept running into:<p><pre><code> - I&#x27;m lazy. My Claude Code workflow became: throw a vague prompt like &quot;turn issues into tasks in Github webhook,&quot; let it run something wrong, then iterate until I realize I could&#x27;ve just coded it myself. Claude Code&#x27;s docs say to plan first, but it&#x27;s not enforced and I can&#x27;t force myself to do it. - Context switching hell. I started using Claude Code asynchronously - give it edit permissions, let it run, alt-tab to work on something else, then come back later to review. But when I return, I need to reconcile what the task was about, context switch back, and iterate. The mental overhead kills any productivity gains. - Tracking sucks. I use Apple Notes with bullet points to track tasks, but it&#x27;s messy. Just like many other developers, I hate PM tools but need some way to stay organized without the bloat. - Review bottleneck. I&#x27;ve never shipped Claude Code output without fixes, at minimum stylistic changes (why does it always add comments even when I tell it not to?). The review&#x2F;test cycle caps me at maybe 3 concurrent tasks. </code></pre> So I built Async:<p><pre><code> - Forces upfront planning, always asks clarifying questions and requires confirmation before executing - Simple task tracking that imports Github issues automatically (other integration coming soon!) - Executes in the cloud, breaks work into subtasks, creates commits, opens PRs - Built-in code review with stacked diffs - comment and iterate without leaving the app - Works on desktop and mobile </code></pre> It works by using a lightweight research agent to scope out tasks and come up with requirements and clarifying questions as needed (e.g., &quot;fix the truncation issue&quot; - &quot;Would you like a tooltip on hover?&quot;). After you confirm requirements, it executes the task by breaking it down into subtasks and then working commit by commit. It uses a mix of Gemini and Claude Code internally and runs all changes in the background in the cloud.<p>You&#x27;ve probably seen tools that do pieces of this, but I think it makes sense as one integrated workflow.<p>This isn&#x27;t for vibe coders. I&#x27;m building a tool that I can use in my day-to-day work. Async is for experienced developers who know their codebases and products deeply. The goal is to make Async the last tool developers need to build something great. Still early and I&#x27;m iterating quickly. Would love to know what you think.<p>P.S. My cofounder loves light mode, I only use dark mode. I won the argument so our tool only supports dark mode. Thumbs up if you agree with me.

When you have multiple AI agents that need to coordinate, persist their state, and query each other&#x27;s status, you typically end up with a mess of Redis&#x2F;Postgres setups, custom queuing, and manual synchronization code.<p>The whole thing is ~3MB, written in Rust for performance and safety, runs in Docker, and handles 1000+ ops&#x2F;sec.

[Other] Show HN: Creao – Vibe coding product for founders Hi HN! I&#x27;m North, DevRel from the CREAO team. We are a 15-20 person startup, and we spent a couple of months building this vibe coding product. We&#x27;ve been exploring the possibilities of how agents should assist people&#x27;s work for productivity in various scenarios.<p>Three months ago, we noticed that all small teams and companies are struggling with subscribing to multiple SaaS tools that never fit their exact needs. Pretty much all founders and SMB professionals need customized productivity tools that fit their daily work routines, but they don&#x27;t have developers to build these lightweight tools for them. So we thought we needed to build a vibe coding product that allows them to ship their own tools in minutes and get rid of these SaaS subscriptions.<p>For our product features, we built it differently from all the other vibe coding products. We want our users to build something actually useful instead of just a product prototype. But the current well-known code agents are performing poorly at building complex data schemas and integrating APIs. So we fine-tuned a small model for the following features:<p>1.Automatically builds complex relational data schemas<p>2.Automated MCP&#x2F;API connections with existing systems<p>With these core capabilities, our code agent can then build internal tools that connect with existing systems with state persistence. For example, I built a dashboard to track my X engagement and export results to a CSV file.<p><a href="https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;1FBBOdrtonlj_56jgQuAoPpGnABB-pvt2&#x2F;view?usp=sharing" rel="nofollow">https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;1FBBOdrtonlj_56jgQuAoPpGnABB...</a><p>This productivity boost is specifically designed for small team founders—you can build your own CRM workflows, data dashboards, revenue tracking, etc. Each of these could cost you $20-50&#x2F;month in SaaS subscriptions.<p>We are still in the early stage and improving our user experience. Our team is delivering new features pretty much every week, and we would love to hear from HN to give us some suggestions on how we can do better. You can always reach me at north@creao.ai. I love to shape the product together with community users. I hope you can find our work very helpful for your productivity.<p>Thanks!

[Other] Show HN: I replaced vector databases with Git for AI memory (PoC) Hey HN! I built a proof-of-concept for AI memory using Git instead of vector databases.<p>The insight: Git already solved versioned document management. Why are we building complex vector stores when we could just use markdown files with Git&#x27;s built-in diff&#x2F;blame&#x2F;history?<p>How it works:<p>Memories stored as markdown files in a Git repo Each conversation = one commit git diff shows how understanding evolves over time BM25 for search (no embeddings needed) LLMs generate search queries from conversation context Example: Ask &quot;how has my project evolved?&quot; and it uses git diff to show actual changes in understanding, not just similarity scores.<p>This is very much a PoC - rough edges everywhere, not production ready. But it&#x27;s been working surprisingly well for personal use. The entire index for a year of conversations fits in ~100MB RAM with sub-second retrieval.<p>The cool part: You can git checkout to any point in time and see exactly what the AI knew then.

Most of the tools I tried felt heavy, tricky to set up, or produced results that didn’t look great, so I wanted something lightweight, modern, and fast. PlutoPrint is built on top of PlutoBook’s rendering engine, which is designed for paged media, and then wrapped with a Python API that makes it easy to turn HTML or XML into crisp PDFs and PNGs. I’ve used it for things like invoices, reports, tickets, and even snapshots, and it can also integrate with Matplotlib to render charts directly into documents.<p>I’d be glad to hear what you think. If you’ve ever had to wrestle with generating PDFs or images from HTML, I hope this feels like a smoother option. Feedback, ideas, or even just impressions are all very welcome, and I’d love to learn how PlutoPrint could be more useful for you.

[Monitoring/Observability] Show HN: Okapi – a metrics engine based on open data formats Hi All I wanted to share an early preview of Okapi an in-memory metrics engine that also integrates with existing datalakes. Modern software systems produce a mammoth amount of telemetry. While we can discuss whether or not this is necessary, we can all agree that it happens.<p>Most metrics engines today use proprietary formats to store data and don’t use disaggregated storage and compute. Okapi changes that by leveraging open data formats and integrating with existing data lakes. This makes it possible to use standard OLAP tools like Snowflake, Databricks, DuckDB or even Jupyter &#x2F; Polars to run analysis workflows (such as anomaly detection) while avoiding vendor lock-in in two ways - you can bring your own workflows and have a swappable compute engine. Disaggregation also reduces Ops burden of maintaining your own storage and the compute engine can be scaled up and down on demand.<p>Not all data can reside in a data-lake&#x2F;object store though - this doesn’t work for recent data. To ease realtime queries Okapi first writes all metrics data to an in memory store and reads on recent data are served from this store. Metrics are rolled up as they arrive which helps ease memory pressure. Metrics are held in-memory for a configurable retention period after which it gets shipped out to object storage&#x2F;datalake (currently only Parquet export is supported). This allows fast reads on recent data while offloading query-processing for older data. On benchmarks queries on in-memory data finish in under a millisecond while having write throughput of ~280k samples per second. On a real deployment, there’d be network delays so YMMV.<p>Okapi it is still early — feedback, critiques, and contributions welcome. Cheers !

[Other] Show HN: Anchor Relay – A faster, easier way to get Let's Encrypt certificates From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates.

[Other] Show HN: Luminal – Open-source, search-based GPU compiler Hi HN, I’m Joe. My friends Matthew, Jake and I are building Luminal (<a href="https:&#x2F;&#x2F;luminalai.com&#x2F;">https:&#x2F;&#x2F;luminalai.com&#x2F;</a>), a GPU compiler for automatically generating fast GPU kernels for AI models. It uses search-based compilation to achieve high performance.<p>We take high level model code, like you&#x27;d have in PyTorch, and generate very fast GPU code. We do that without using LLMs or AI - rather, we pose it as a search problem. Our compiler builds a search space, generates millions of possible kernels, and then searches through it to minimize runtime.<p>You can try out a demo in `demos&#x2F;matmul` on mac to see how Luminal takes a naive operation, represented in our IR of 12 simple operations, and compiles it to an optimized, tensor-core enabled Metal kernel. Here’s a video showing how: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;P2oNR8zxSAA" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;P2oNR8zxSAA</a><p>Our approach differs significantly from traditional ML libraries in that we ahead-of-time compile everything, generate a large search space of logically-equivalent kernels, and search through it to find the fastest kernels. This allows us to leverage the Bitter Lesson to discover complex optimizations like Flash Attention entirely automatically without needing manual heuristics. The best rule is no rule, the best heuristic is no heuristic, just search everything.<p>We’re working on bringing CUDA support up to parity with Metal, adding more flexibility to the search space, adding full-model examples (like Llama), and adding very exotic hardware backends.<p>We aim to radically simplify the ML ecosystem while improving performance and hardware utilization. Please check out our repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;luminal-ai&#x2F;luminal" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;luminal-ai&#x2F;luminal</a> and I’d love to hear your thoughts!

[CLI Tool] Show HN: Claude Code workflow: PRDs → GitHub Issues → parallel execution I built a lightweight project management workflow to keep AI-driven development organized.<p>The problem was that context kept disappearing between tasks. With multiple Claude agents running in parallel, I’d lose track of specs, dependencies, and history. External PM tools didn’t help because syncing them with repos always created friction.<p>The solution was to treat GitHub Issues as the database. The &quot;system&quot; is ~50 bash scripts and markdown configs that:<p>- Brainstorm with you to create a markdown PRD, spins up an epic, and decomposes it into tasks and syncs them with GitHub issues - Track progress across parallel streams - Keep everything traceable back to the original spec - Run fast from the CLI (commands finish in seconds)<p>We’ve been using it internally for a few months and it’s cut our shipping time roughly in half.

[API/SDK] Show HN: Lemonade: Run LLMs Locally with GPU and NPU Acceleration Lemonade is an open-source SDK and local LLM server focused on making it easy to run and experiment with large language models (LLMs) on your own PC, with special acceleration paths for NPUs (Ryzen™ AI) and GPUs (Strix Halo and Radeon™).<p>Why?<p>There are three qualities needed in a local LLM serving stack, and none of the market leaders (Ollama, LM Studio, or using llama.cpp by itself) deliver all three: 1. Use the best backend for the user’s hardware, even if it means integrating multiple inference engines (llama.cpp, ONNXRuntime, etc.) or custom builds (e.g., llama.cpp with ROCm betas). 2. Zero friction for both users and developers from onboarding to apps integration to high performance. 3. Commitment to open source principles and collaborating in the community.<p>Lemonade Overview:<p>Simple LLM serving: Lemonade is a drop-in local server that presents an OpenAI-compatible API, so any app or tool that talks to OpenAI’s endpoints will “just work” with Lemonade’s local models. Performance focus: Powered by llama.cpp (Vulkan and ROCm for GPUs) and ONNXRuntime (Ryzen AI for NPUs and iGPUs), Lemonade squeezes the best out of your PC, no extra code or hacks needed. Cross-platform: One-click installer for Windows (with GUI), pip&#x2F;source install for Linux. Bring your own models: Supports GGUFs and ONNX. Use Gemma, Llama, Qwen, Phi and others out-of-the-box. Easily manage, pull, and swap models. Complete SDK: Python API for LLM generation, and CLI for benchmarking&#x2F;testing. Open source: Apache 2.0 (core server and SDK), no feature gating, no enterprise “gotchas.” All server&#x2F;API logic and performance code is fully open; some software the NPU depends on is proprietary, but we strive for as much openness as possible (see our GitHub for details). Active collabs with GGML, Hugging Face, and ROCm&#x2F;TheRock.<p>Get started:<p>Windows? Download the latest GUI installer from <a href="https:&#x2F;&#x2F;lemonade-server.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lemonade-server.ai&#x2F;</a><p>Linux?

Point any OpenAI-compatible app (chatbots, coding assistants, GUIs, etc.) at http:&#x2F;&#x2F;localhost:8000&#x2F;api&#x2F;v1 Use the CLI to run&#x2F;load&#x2F;manage models, monitor usage, and tweak settings such as temperature, top-p and top-k. Integrate via the Python API for direct access in your own apps or research.<p>Who is it for?<p>Developers: Integrate LLMs into your apps with standardized APIs and zero device-specific code, using popular tools and frameworks. LLM Enthusiasts, plug-and-play with: Morphik AI (contextual RAG&#x2F;PDF Q&amp;A) Open WebUI (modern local chat interfaces) Continue.dev (VS Code AI coding copilot) …and many more integrations in progress! Privacy-focused users: No cloud calls, run everything locally, including advanced multi-modal models if your hardware supports it.<p>Why does this matter?<p>Every month, new on-device models (e.g., Qwen3 MOEs and Gemma 3) are getting closer to the capabilities of cloud LLMs. We predict a lot of LLM use will move local for cost reasons alone. Keeping your data and AI workflows on your own hardware is finally practical, fast, and private, no vendor lock-in, no ongoing API fees, and no sending your sensitive info to remote servers. Lemonade lowers friction for running these next-gen models, whether you want to experiment, build, or deploy at the edge. Would love your feedback! Are you running LLMs on AMD hardware? What’s missing, what’s broken, what would you like to see next? Any pain points from Ollama, LM Studio, or others you wish we solved?

[Other] Show HN: Built a memory layer that stops AI agents from forgetting everything Tired of AI coding tools that forget everything between sessions? Every time I open a new chat with Claude or fire up Copilot, I&#x27;m back to square one explaining my codebase structure.<p>So I built something to fix this. It&#x27;s called In Memoria. Its an MCP server that gives AI tools persistent memory. Instead of starting fresh every conversation, the AI remembers your coding patterns, architectural decisions, and all the context you&#x27;ve built up.<p>The setup is dead simple: `npx in-memoria server` then connect your AI tool. No accounts, no data leaves your machine.<p>Under the hood it&#x27;s TypeScript + Rust with tree-sitter for parsing and vector storage for semantic search. Supports JavaScript&#x2F;TypeScript, Python, and Rust so far.<p>It originally started as a documentation tool but had a realization - AI doesn&#x27;t need better docs, it needs to remember stuff. Spent the last few months rebuilding it from scratch as this memory layer.<p>It&#x27;s working pretty well for me but curious what others think, especially about the pattern learning part.

[Other] Show HN: GiralNet – A Privacy Network for Your Team (Not the World) Hello, for some time I&#x27;ve been developing this project now that I am happy that it finally can see the light. I love Tor, but I believe the biggest thing with Tor is that the nodes are strangers which in itself requires some sort of level in just that, complete strangers.<p>For this reason, I decided to build this private network inspired by the Onion router. Unlike other public networks, GiralNet is not for anonymous connections to strangers. It is built for small teams or groups who want privacy but also need a level of trust. It assumes that the people running the nodes in the network are known and verifiable. This provides a way for a group to create their own private and secure network, where the infrastructure is controlled and the people behind the nodes are accountable. The goal is to provide privacy without relying on a large, anonymous public network.<p>In terms of technical details, it is a SOCKS5 proxy that routes internet traffic through a series of other computers. It does this by wrapping your data in multiple layers of encryption, just like the onion router does it. Each computer in the path unwraps one layer to find the next destination, but never knows the full path. This makes it difficult for any single party to see both where the traffic came from and where it is going.<p>I will gladly answer any questions you might have, thank you.

[API/SDK] Show HN: I'm building a "work visa" API for AI agents Hey HN,<p>I’m Chris, a solo dev in Melbourne AU. For the past month I&#x27;ve been spending my after work hours building AgentVisa. I&#x27;m both excited (and admittedly nervous) to be sharing it with you all today.<p>I&#x27;ve been spending a lot of time thinking about the future of AI agents and the more I experimented, the more I realized I was building on a fragile foundation. How do we build trust into these systems? How do we know what our agents are doing, and who gave them permission?<p>My long-term vision is to give developers an &quot;Agent Atlas&quot; - a clear map of their agentic workforce, showing where they&#x27;re going and what they&#x27;re authorized to do. The MVP I&#x27;m launching today is that first step.<p>The core idea is simple: stop giving agents a permanent &quot;passport&quot; (a static API key) and start giving them a temporary &quot;work visa&quot; for each specific task. AgentVisa is a simple API that issues secure, short-lived credentials, linking an agent&#x27;s task back to a specific user and a set of permissions.<p>To make this more concrete, I&#x27;ve put together a demo you can run locally showing how an agentic customer service bot uses AgentVisa to access an internal API. You can see it here: <a href="https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-customer-support-demo" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-customer-support-demo</a><p>Under the hood it’s JWTs for now. But the product isn&#x27;t the token - it&#x27;s the simple, secure workflow for delegating authority. It&#x27;s a pattern I needed for my own projects and I&#x27;m hoping it&#x27;s useful to you too.<p>I know there&#x27;s a &quot;two-sided problem&quot; here - this is most useful when the server an agent connects to can also verify the agent&#x27;s authenticity. Right now it&#x27;s ideal for securing your own internal services, which is where I started. My hope is that over time this can be built into a standard that more services adopt.<p>I&#x27;m keen for feedback from fellow devs working with AI agents. Does this problem of agent identity and auditability resonate with you? Is the &quot;visa vs. passport&quot; concept clear? What would you want to see on that &quot;Agent Atlas&quot; I mentioned?<p>The Python SDK is open and on GitHub, and there&#x27;s a generous free tier so you can build with it right away. I&#x27;ll be here to answer as best I can any questions you have. Thanks for checking it out!<p>SDK: <a href="https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-python" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-python</a> Demo: <a href="https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-customer-support-demo" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;AgentVisa&#x2F;agentvisa-customer-support-demo</a><p>Note: for us down under it’s getting late!

[Database] Show HN: Chroma Cloud – serverless search database for AI Hey HN - I’m Jeff, co-founder of Chroma.<p>In December of 2022, I was scrolling Twitter in the wee-hours of the morning holding my then-newborn daughter. ChatGPT had launched, and we were all figuring out what this technology was and how to make it useful. Developers were using retrieval to bring their data to the models - and so I DM’d every person who had tweeted about “embeddings” in the entire month of December. (it was only 120 people!) I saw then how AI was going to need to search to all the world’s information to build useful and reliable applications.<p>Anton Troynikov and I started Chroma with the beliefs that:<p>1. AI-based systems were way too difficult to productionize<p>2. Latent space was incredibly important to improving AI-based systems (no one understood this at the time)<p>On Valentines Day 2023, we launched first version of Chroma and it immediately took off. Chroma made retrieval just work. Chroma is now a large open-source project with 21k+ stars and 5M monthly downloads, used at companies like Apple, Amazon, Salesforce, and Microsoft.<p>Today we’re excited to launch Chroma Cloud - our fully-managed offering backed by an Apache 2.0 serverless database called Chroma Distributed. Chroma Distributed is written in Rust and uses object-storage for extreme scalability and reliability. Chroma Cloud is fast and cheap. Leading AI companies such as Factory, Weights &amp; Biases, Propel, and Foam already use Chroma Cloud in production to power their agents. It brings the “it just works” developer experience developers have come to know Chroma for - to the Cloud.<p>Try it out and let me know what you think!<p>— Jeff

[API/SDK] Launch HN: Reality Defender (YC W22) – API for Deepfake and GenAI Detection Hi HN! This is Ben from Reality Defender (<a href="https:&#x2F;&#x2F;www.realitydefender.com">https:&#x2F;&#x2F;www.realitydefender.com</a>). We build real-time multimodal and multi-model deepfake detection for Fortune 100s and governments all over the world. (We even won the RSAC Innovation Showcase award for our work: <a href="https:&#x2F;&#x2F;www.prnewswire.com&#x2F;news-releases&#x2F;reality-defender-wins-most-innovative-startup-at-rsa-conference-2024-innovation-sandbox-302137326.html" rel="nofollow">https:&#x2F;&#x2F;www.prnewswire.com&#x2F;news-releases&#x2F;reality-defender-wi...</a>)<p>Today, we’re excited to share our public API and SDK, allowing anyone to access our platform with 2 lines of code: <a href="https:&#x2F;&#x2F;www.realitydefender.com&#x2F;api">https:&#x2F;&#x2F;www.realitydefender.com&#x2F;api</a><p>Back in W22, we launched our product to detect AI-generated media across audio, video, and images: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=30766050">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=30766050</a><p>That post kicked off conversations with devs, security teams, researchers, and governments. The most common question: &quot;Can we get API&#x2F;SDK access to build deepfake detection into our product?&quot;<p>We’ve heard that from solo devs building moderation tools, fintechs adding ID verification, founders running marketplaces, and infrastructure companies protecting video calls and onboarding flows. They weren’t asking us to build anything new; they simply wanted access to what we already had so they could plug it in and move forward.<p>After running pilots and engagements with customers, we’re finally ready to share our public API and SDK. Now anyone can embed deepfake detection with just two lines of code, starting at the low price of free.<p><a href="https:&#x2F;&#x2F;www.realitydefender.com&#x2F;api">https:&#x2F;&#x2F;www.realitydefender.com&#x2F;api</a><p>Our new developer tools support detection across images, voice, video, and text — with the former two available as part of the free tier. If your product touches KYC, UGC, support workflows, communications, marketplaces, or identity layers, you can now embed real-time detection directly in your stack. It runs in the cloud, and longstanding clients using our platform have also deployed on-prem, at the edge, or on fully airgapped systems.<p>SDKs are currently available in Python, Java, Rust, TypeScript, and Go. The first 50 scans per month are free, with usage-based pricing beyond that. If you’re working on something that requires other features or streaming access (like real-time voice or video), email us directly at yc@realitydefender.com<p>Much has changed since 2022. The threats we imagined back then are now showing up in everyday support tickets and incident reports. We’ve witnessed voice deepfakes targeting bank call centers to commit real-time fraud; fabricated documents and AI-generated selfies slip through KYC and IDV onboarding systems; fake dating profiles, AI-generated marketplace sellers, and “verified” influencers impersonating real people. Political disinformation videos and synthetic media leaks have triggered real-world legal and PR crises. Even reviews, support transcripts, and impersonation scripts are increasingly being generated by AI. Detection remains harder than we first expected since we began in 2021. New generation methods emerge every few weeks that invalidate prior assumptions. This is why we are committed to building every layer of this ourselves. We don’t license or white-label detection models; everything we deploy is built in-house by our team.<p>Since our original launch, we’ve worked with tier-one banks, global governments, and media companies to deploy detection inside their highest-risk workflows. However, we always believed the need wasn’t limited to large institutions, but everywhere. It showed up in YC office hours, in early bug reports, and in group chats after our last HN post.<p>We’ve taken our time to make sure this was built well, flexible enough for startups, and battle-tested enough to trust in production. The API you can use today is the same one powering many of our enterprise deployments.<p>Our goal is to make Reality Defender feel like Stripe, Twilio, or Plaid — an invisible, trusted layer that you can drop into your system to protect what matters. We feel deepfake detection is a key component of critical infrastructure, and like any good infrastructure, it should be modular, reliable, and boring (in the best possible way).<p>Reality Defender is already in the Zoom marketplace and will be on the Teams marketplace soon. We will also power deepfake detection for identity workflows, support platforms, and internal trust and safety pipelines.<p>If you&#x27;re building something where trust, identity, or content integrity matter, or if you’ve run into weird edge cases you can’t explain, we’d love to hear from you.<p>You can get started here: <a href="https:&#x2F;&#x2F;realitydefender.com&#x2F;api">https:&#x2F;&#x2F;realitydefender.com&#x2F;api</a><p>Or you can try us for free two different ways:<p>1) 1-click add to Zoom &#x2F; Teams to try in your own calls immediately.<p>2) Email us up to 50 files at yc@realitydefender.com and we’ll scan them for you — no setup required.<p>Thanks again to the HN community for helping launch us three years ago. It’s been a wild ride, and we’re excited to share something new. We live on HN ourselves and will be here for all your feedback. Let us know what you think!

I&#x27;m Arindam, part of the team behind Memori (<a href="https:&#x2F;&#x2F;memori.gibsonai.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;memori.gibsonai.com&#x2F;</a>).<p>Memori adds a stateful memory engine to AI agents, enabling them to stay consistent, recall past work, and improve over time. With Memori, agents don’t lose track of multi-step workflows, repeat tool calls, or forget user preferences. Instead, they build up human-like memory that makes them more reliable and efficient across sessions.<p>We’ve also put together demo apps (a personal diary assistant, a research agent, and a travel planner) so you can see memory in action.<p>Current LLMs are stateless — they forget everything between sessions. This leads to repetitive interactions, wasted tokens, and inconsistent results. When building AI agents, this problem gets even worse: without memory, they can’t recover from failures, coordinate across steps, or apply simple rules like “always write tests.”<p>We realized that for AI agents to work in production, they need memory. That’s why we built Memori.<p>Memori uses a multi-agent architecture to capture conversations, analyze them, and decide which memories to keep active. It supports three modes:<p>- Conscious Mode: short-term memory for recent, essential context. - Auto Mode: dynamic search across long-term memory. - Combined Mode: blends both for fast recall and deep retrieval.<p>Under the hood, Memori is SQL-first. You can use SQLite, PostgreSQL, or MySQL to store memory with built-in full-text search, versioning, and optimization. This makes it simple to deploy, production-ready, and extensible.<p>Memori is backed by GibsonAI’s database infrastructure, which supports:<p>- Instant provisioning - Autoscaling on demand - Database branching &amp; versioning - Query optimization - Point of recovery<p>This means memory isn’t just stored, it’s reliable, efficient, and scales with real-world workloads.<p>We’ve open-sourced Memori under the Apache 2.0 license so anyone can build with it. You can check out the GitHub repo here: <a href="https:&#x2F;&#x2F;github.com&#x2F;GibsonAI&#x2F;memori" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;GibsonAI&#x2F;memori</a>, explore the docs, and join our community on Discord.<p>We’d love to hear your thoughts. Please dive into the code, try out the demos, and share feedback, your input will help shape where we take Memori from here.

It&#x27;s designed to make it easier to edit and reorganize the output of the tree command.<p>You can try it out here: <a href="https:&#x2F;&#x2F;reorx.github.io&#x2F;asciitreeman&#x2F;" rel="nofollow">https:&#x2F;&#x2F;reorx.github.io&#x2F;asciitreeman&#x2F;</a><p>And the source code is on GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;reorx&#x2F;asciitreeman" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;reorx&#x2F;asciitreeman</a><p>Some of the key features include visual tree editing with drag-and-drop-like operations, real-time sync where changes are immediately reflected in the ASCII output, keyboard shortcuts for navigation (J&#x2F;K or arrow keys), and auto-saving your work to local storage.<p>What&#x27;s interesting is that I used Claude Code to &quot;vibe-code&quot; this project in a very short amount of time. It was a fun experiment in AI-assisted development. For those curious about the process, I&#x27;ve included the prompts and specifications I used in the source code. You can check them out in the spec.md and CLAUDE.md files in the repository.<p>Hop you find it useful!

[CLI Tool] Show HN: Doxx – Terminal .docx viewer inspired by Glow I got tired of open file.docx → wait 8 seconds → close Word just to read a document, so I built a terminal-native Word viewer!<p>What it does:<p>* View `.docx` files directly in your terminal with (mostly) proper formatting<p>* Tables actually look like tables (with Unicode borders!)<p>* Nested lists work correctly with indentation<p>* Full-text search with highlighting<p>* Copy content straight to clipboard with `c`<p>* Export to markdown&#x2F;CSV&#x2F;JSON<p>Why I made this:<p>Working on servers over SSH, I constantly hit Word docs I needed to check quickly. The existing solutions I&#x27;m aware of either strip all formatting (docx2txt) or require GUI apps. Wanted something that felt as polished as [glow](<a href="https:&#x2F;&#x2F;github.com&#x2F;charmbracelet&#x2F;glow" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;charmbracelet&#x2F;glow</a>) but for Word documents.<p>The good stuff:<p>* 50ms startup vs Word&#x27;s 8+ seconds<p>* Works over SSH (obviously)<p>* Preserves document structure and formatting<p>* Smart table alignment based on data types<p>* Interactive outline view for long docs<p>Built with Rust + ratatui and heavily inspired by Charm&#x27;s [glow](<a href="https:&#x2F;&#x2F;github.com&#x2F;charmbracelet&#x2F;glow" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;charmbracelet&#x2F;glow</a>) package for viewing Markdown in the CLI (built in Go)!<p><pre><code> # Install cargo install --git https:&#x2F;&#x2F;github.com&#x2F;bgreenwell&#x2F;doxx # Use doxx quarterly-report.docx </code></pre> Still early but handles most Word docs I throw at it.

[Other] Show HN: Lue – Terminal eBook Reader with Text-to-Speech Shown HN: Lue - Terminal eBook Reader with Text-to-Speech<p>Hello,<p>Just went live on GitHub with this project.<p>I really enjoy listening to my eBooks as audiobooks but was frustrated by the available options. Converting books into audiobooks with scripts is tedious, and most tools stumble over footnotes, headers, or formatting. I wanted something simple: just throw a book at it, and it starts reading immediately without any clicking or loading.<p>I also wanted it to be customizable and modular because new, better TTS engines are released all the time. For this initial release, I settled on Edge and Kokoro because they’re both fast (real-time) and good quality. I’ve already made modules for Kitten TTS, Gemini and a few others, and they work too. So I hope this setup is future-proof.<p>Here’s what Lue supports:<p>Multi-format: EPUB, PDF, TXT, DOCX, HTML, RTF, and Markdown.<p>Modular TTS system: Default Edge TTS (online) and Kokoro TTS (offline&#x2F;local), with an architecture to add more models.<p>Rich terminal UI: Full keyboard and mouse support, customizable color themes, smooth scrolling.<p>Smart persistence: Automatically saves reading progress across sessions.<p>Cross-platform &amp; multilingual: macOS, Linux, Windows, supporting 100+ languages.<p>I’d love feedback on both usability and the TTS experience. Are there any features you wish it had?

[IDE/Editor] Show HN: Embedr – Agentic IDE for Arduino, ESP32, and More Hi HN,<p>I’m building an agentic IDE for hardware developers. It currently supports Arduino, ESP32, ESP8266, and a bunch of other boards (mostly hobbyist for now, but expanding to things like PlatformIO).<p>It can already write and debug hardware projects end-to-end on its own. The goal is to have it also generate breadboard views (Fritzing-style), PCB layouts, and schematics. Basically a generative EDA tool.<p>Right now, it’s already a better drop-in replacement for the Arduino IDE.<p>Would love feedback from folks here.

[Other] Show HN: I built an app to block Shorts and Reels I wanted to find a way to use Instagram without ending up scrolling for two hours every time I open the app to see a friend&#x27;s story.<p>Most screen time apps I found focus on blocking the app itself instead of the addictive feed, so I created this app to allow me to keep using the &quot;healthy&quot; and &quot;social&quot; features and block the infinite scrolling (Reels)<p>After implementing the block on Instagram Reels, I got addicted to YouTube Shorts and Reddit feed. So, I extended the app to cover these as well.<p>To avoid replacing the scrolling for regular feeds, I also added a feature that shows a pop-up when I&#x27;m overscrolling in any app. It forces me to stop and think for a minute before I continue scrolling.<p>I built it on Android Studio, using Kotlin and Jetpack Compose for the UI. I use the Accessibility Service to detect scrolls and navigate out of them. Unfortunately, this only works for Android. There is no way (as far as I know) to do this on iOS.<p>I&#x27;d love to hear your thoughts

[DevOps] Show HN: Edka – Kubernetes clusters on your own Hetzner account Hi HN,<p>I’ve been working with Kubernetes for over a decade, since the alpha days, and was involved in kube-aws project before AWS launched EKS. For the past four years, I’ve been helping friends and small businesses cut costs by running Kubernetes on Hetzner Cloud, which I’ve found to be rock solid and by far the best priced provider.<p>Provisioning a cluster on Hetzner is now straightforward, thanks to tools like k3s and hetzner-k3s, but configuring it for your specific needs still takes time and expertise. I built Edka to make that part easy: spin up a production ready cluster in ~2 minutes, then choose how low level or automated you want to go.<p>How it works:<p>Layer 1 – Cluster provisioning - Creates a k3s-based Kubernetes cluster on Hetzner (lightweight, easy to manage, scales well).<p>Layer 2 – Add-ons - One-click deploy for metrics-server, cert-manager, and various operators; preconfigured for Hetzner, no extra setup needed.<p>Layer 3 – Applications - Minimal config UIs for apps built on top of add-ons. - Example: Need PostgreSQL? Fill a few fields → platform installs CloudNativePG → provisions HA PostgreSQL with PITR → gives ready to use endpoints. Backups can be restored to any point in time with a click. Quick demo: <a href="https:&#x2F;&#x2F;edka.io&#x2F;apps&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;apps&#x2F;</a><p>Layer 4 – Deployments - Connect your CI to push container images to a public&#x2F;private registry. - Edka updates deployments automatically (with semantic versioning rules), supports instant rollbacks, autoscaling, persistent volumes, secrets&#x2F;env imports, and quick public exposure. Quick demo: <a href="https:&#x2F;&#x2F;edka.io&#x2F;deployments&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;deployments&#x2F;</a><p>Tech stack: TypeScript, React + Tailwind CSS, PostgreSQL, Redis, BullMQ, Vault + AWS KMS to encrypted sensitive data.<p>The platform is still in beta and I’m building it in my spare time, so there are some rough edges, but I’d love feedback from anyone running Kubernetes on Hetzner, exploring alternatives to EKS&#x2F;GKE&#x2F;AKS or looking to automate their infrastructure with Kubernetes.<p>More details: <a href="https:&#x2F;&#x2F;edka.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;</a><p>Thank you!

[Other] Show HN: MCP Security Suite Hi HN!<p>We kept seeing devs get pwned through MCP tools in ways that security scanners completely miss. So we built an open-source analyzer to catch these attacks. Our first OSS by Mighty team.<p>The problem: At Defcon, we saw MCP exploits with 100% success rate against Claude and Llama. Three attack patterns:<p>Hidden Unicode in &quot;error messages&quot; - Paste a colleague&#x27;s error into Claude, your SSH keys get exfiltrated Trusted tool updates - That database tool you&#x27;ve used for months? Last week&#x27;s update added credential theft Tool redefinition - Malicious tool redefines &quot;deploy to prod&quot; to run attacker&#x27;s script<p>Traditional scanners (CodeQL, SonarQube) catch &lt;15% of these. They&#x27;re looking for SQLi, not prompt injections hidden in tool descriptions.<p>What we built: git clone <a href="https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security</a><p>python analyzers&#x2F;comprehensive_mcp_analyzer.py &#x2F;path&#x2F;to&#x2F;your&#x2F;mcp&#x2F;tool<p>Scans for prompt injection, credential exfil, suspicious updates, tool shadowing. Runtime wrapper adds &lt;10ms overhead. Fully local, no telemetry.<p>Why this matters: 43% of MCP tools have command injection vulns. GitHub&#x27;s own MCP server was exploitable. We found Fortune 500s running database-connected MCP tools that hadn&#x27;t been audited since installation. We went from paranoid code review to &quot;AI said it works&quot; in 18 months. The magic is real, but so are the vulnerabilities.<p>Demo: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;e830c56d39254a788776358c5b03fdc3" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;e830c56d39254a788776358c5b03fdc3</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security</a><p>Would love feedback - what MCP security issues have you seen?

Think Supabase, but for MongoDB: auth, cron jobs, email, monitoring, without glue code before you can ship.<p>As Karpathy (and many of us) noted, getting from prototype to production is mostly painful integration work. The pieces exist, but stitching them together reliably is the hard part: <a href="https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1905051558783418370" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1905051558783418370</a>.

What you get out of the box:<p>- Authentication &#x2F; user management<p>- Database<p>- Email integration (3rd party, but things like user verification emails work out of the box)<p>- AI integration<p>- Cron jobs<p>- Monitoring &#x2F; Telemetry<p>- Configs &amp; secrets<p>- Analytics (coming soon)<p>- File uploads (coming soon)<p>How it runs: A Node.js backend with MongoDB. It&#x27;s frontend-agnostic, so you can use our minimal Vite + React starter or drop Modelence behind an existing Next.js (or any) frontend.<p>We&#x27;re also building a managed cloud, similar to what Vercel is for Next.js, except Modelence focuses on the backend instead of the frontend (Vercel is great for content sites like landing pages, blogs, etc, but things like persistent connections and complex backend logic outgrow it quickly). You can find a quick demo here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=S4f22FyPpI8" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=S4f22FyPpI8</a><p>We&#x27;re looking for early users (especially TS teams on MongoDB). Tell us what&#x27;s missing, what&#x27;s confusing, and what you&#x27;d want before trusting this in prod. Happy to answer anything!

[Other] Show HN: E-commerce data from 100k stores that is refreshed daily Hi HN! I&#x27;m building Agora, an AI search engine for e-commerce that returns results in under 300ms. We&#x27;ve indexed 30M products from 100k stores and made them easy to purchase using AI agents.<p>After launching here on HN, a large enterprise reached out to pay for access to the raw data. We serviced the contract manually to learn the exact workflow and then decided to productize the &quot;Data Connector&quot; to help us scale to more customers.<p>The Data Connector enables developers to select any of our 100k stores in the index, view sample data, format the output, and export the up-to-date data. Data can be exported as CSV or JSON.<p>We&#x27;ve built crawlers for Shopify, WooCommerce, Squarespace, Wix, and custom built stores to index the store information, product data, stock, reviews, and more. The primary technical challenge is to recrawl the entire dataset every 24 hours. We do this with a series of servers that &quot;recrawl&quot; different store-types with rotating local proxies and then add changes to a queue to be updated in our search index. Our primary database is Mongo and our search runs on self-hosted Meilisearch on high RAM servers.<p>My vision is to index the world&#x27;s e-commerce data. I believe this will create market efficiencies for customers, developers, and merchants.<p>I&#x27;d love your feedback!

[CLI Tool] Show HN: Yet another memory system for LLMs Built this for my LLM workflows - needed searchable, persistent memory that wouldn&#x27;t blow up storage costs. I also wanted to use it locally for my research. It&#x27;s a content-addressed storage system with block-level deduplication (saves 30-40% on typical codebases). I have integrated the CLI tool into most of my workflows in Zed, Claude Code, and Cursor, and I provide the prompt I&#x27;m currently using in the repo.<p>The project is in C++ and the build system is rough around the edges but is tested on macOS and Ubuntu 24.04.

[API/SDK] Show HN: Inworld Runtime – A C++ graph-based runtime for production AI apps Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we&#x27;re releasing today in public preview.<p>We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I&#x2F;O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models.<p>Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as graphs. For instance, a basic voice-to-voice agent consists of STT → LLM → TTS nodes, while the connecting edges stream data and enforce conditions. This graph engine is portable (Linux, Windows, macOS) and can run on-device.<p>We built a few key features on top of this C++ core:<p>- Extensions. Runtime architecture decouples graph definition from implementation. If a pre-built component doesn&#x27;t exist, you can register your own custom node&#x2F;code and reuse it in any graph without writing any glue code.<p>- Routers. You can dynamically select models&#x2F;settings on the per-node basis depending on the traffic as well as configure policies for fallbacks and retries to get the app ready for production.<p>- The Portal. A web-based control plane UI to deploy graphs, push config changes instantly, run A&#x2F;B tests on live traffic, and monitor your app with logs, traces, and metrics.<p>- Unified API. Use our optimized models or route to providers like OpenAI, Anthropic, and Google through a single, consistent interface and one API key.<p>We have a Node.js SDK out now, with Python, Unity, Unreal, and native C++ coming soon. We plan to open-source the SDKs, starting with Node.js.<p>The docs are here: <a href="https:&#x2F;&#x2F;docs.inworld.ai&#x2F;docs&#x2F;runtime&#x2F;overview" rel="nofollow">https:&#x2F;&#x2F;docs.inworld.ai&#x2F;docs&#x2F;runtime&#x2F;overview</a><p>We&#x27;re eager for feedback from fellow engineers and builders. What do you think?

[API/SDK] Show HN: Vaultrice – A real-time key-value store with a localStorage API Hi HN,<p>I&#x27;m Adriano, one of the makers of Vaultrice. I&#x27;m excited (and a little nervous!) to share what we&#x27;ve been building.<p>For years, we found ourselves in a frustrating loop: whenever we needed a simple real-time feature—like a &quot;who&#x27;s online&quot; list, a collaborative app, or just sharing state between a marketing site and our main app — we&#x27;d end up spending days setting up the same stack or discarded to do it. Setting it up, it always involved wiring together a database, a WebSocket server, an API, and managing the connection state. It felt like massive overkill for what we were trying to achieve.<p>We wanted a tool that felt as simple to use as the browser&#x27;s `localStorage` API but worked across domains and devices, with real-time sync and security built-in.<p>So, we built Vaultrice.<p>It’s a key-value data store built on top of Cloudflare&#x27;s Durable Objects, which gives you a strongly consistent backend for each data object. You interact with it through our TS&#x2F;JS SDK, which comes in two flavors:<p>1. `NonLocalStorage`: A low-level client with a `localStorage`-like API (`setItem`, `getItem`, etc.) plus real-time events and presence (`.on()`, `.join()`).<p>2. `SyncObject`: A higher-level, reactive JavaScript Proxy. You just change a property on an object (`doc.title = &#x27;New Title&#x27;`), and it automatically syncs to all other connected clients.<p>The goal is to let you build the real-time features you want in minutes, not days. We&#x27;ve also put a lot of thought into a layered security model, allowing you to go from simple API key restrictions all the way to server-signed object IDs and client-side E2EE.<p>We’ve just launched and would be grateful for any feedback from the HN community. What do you think of the API design? Are there use cases we haven&#x27;t considered? Any thoughts on the security model?<p>We&#x27;ll be here (or via email (support@vaultrice.com)) to answer any questions. Thanks for checking it out!

[Other] Show HN: Omnara – Run Claude Code from anywhere Hey ya’ll, Ishaan and Kartik here. We&#x27;re building Omnara (<a href="https:&#x2F;&#x2F;omnara.com&#x2F;">https:&#x2F;&#x2F;omnara.com&#x2F;</a>), an “agent command center” that lets you launch and control Claude Code from anywhere: terminal, web, or mobile — and easily switch between them.<p>Run &#x27;pip install omnara &amp;&amp; omnara&#x27;, and you&#x27;ll have a regular Claude Code session. But you can continue that same session from our web dashboard (<a href="https:&#x2F;&#x2F;omnara.com&#x2F;">https:&#x2F;&#x2F;omnara.com&#x2F;</a>) or mobile app (<a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;omnara-ai-command-center&#x2F;id6748426727">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;omnara-ai-command-center&#x2F;id674...</a>).<p>Check out a demo here: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;03d30efcf8e44035af03cbfebf840c73" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;03d30efcf8e44035af03cbfebf840c73</a>.<p>Before Omnara, we felt stuck watching Claude Code think and write code, waiting 5-10 minutes just to provide input when needed. Now with Omnara, I can start a Claude Code session and if I need to leave my laptop, I can respond from my phone anywhere. Some places I&#x27;ve coded from include my bed, on a walk, in an Uber, while doing laundry, and even on the toilet.<p>There are many new Claude Code wrappers (e.g., Crystal, Conductor), but none keep the native Claude Code terminal experience while allowing interaction outside the terminal, especially on mobile. On the other hand, tools like Vibetunnel or Termius replicate the terminal experience but lack push notifications, clean UIs for answering questions or viewing git diffs, and easy setup.<p>We wanted our integration to fully mirror the native Claude Code experience, including terminal output, permissions, notifications, and mode switching. The Claude Code SDK and hooks don&#x27;t support all of this, so we made a CLI wrapper that parses the session file at ~&#x2F;.claude&#x2F;projects and the terminal output to capture user and agent messages. We send these messages to our platform, where they&#x27;re displayed in the web and mobile apps in real time via SSE. Our CLI wrapper monitors for input from both the Omnara platform and the Claude Code CLI, continuing execution when the user responds from either location. Our entire backend is open source: <a href="https:&#x2F;&#x2F;github.com&#x2F;omnara-ai&#x2F;omnara" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;omnara-ai&#x2F;omnara</a>.<p>Omnara isn&#x27;t just for Claude Code. It&#x27;s a general framework for any AI agent to send messages and push notifications to humans when they need input. For example, I&#x27;ve been using it as a human-in-the-loop node in n8n workflows for replying to emails. But every Claude Code user we show it to gets excited about that application specifically so that’s why we’re launching that first :)<p>Omnara is free for up to 10 agent sessions per month, then $9&#x2F;month for unlimited sessions. Looking forward to your feedback and hearing your thoughts and comments!

[Other] Show HN: Real-time privacy protection for smart glasses I built a live video privacy filter that helps smart glasses app developers handle privacy automatically.<p>How it works: You can replace a raw camera feed with the filtered stream in your app. The filter processes a live video stream, applies privacy protections, and outputs a privacy-compliant stream in real time. You can use this processed stream for AI apps, social apps, or anything else.<p>Features: Currently, the filter blurs all faces except those who have given consent. Consent can be granted verbally by saying something like &quot;I consent to be captured&quot; to the camera. I&#x27;ll be adding more features, such as detecting and redacting other private information, speech anonymization, and automatic video shut-off in certain locations or situations.<p>Why I built it: While developing an always-on AI assistant&#x2F;memory for glasses, I realized privacy concerns would be a critical problem, for both bystanders and the wearer. Addressing this involves complex issues like GDPR, CCPA, data deletion requests, and consent management, so I built this privacy layer first for myself and other developers.<p>Reference app: There&#x27;s a sample app (.&#x2F;examples&#x2F;rewind&#x2F;) that uses the filter. The demo video is in the README, please check it out! The app shows the current camera stream and past recordings, both privacy-protected, and will include AI features using the recordings.<p>Tech: Runs offline on a laptop. Built with FFmpeg (stream decode&#x2F;encode), OpenCV (face recognition&#x2F;blurring), Faster Whisper (voice transcription), and Phi-3.1 Mini (LLM for transcription analysis).<p>I&#x27;d love feedback and ideas for tackling the privacy challenges in wearable camera apps!

After dealing with tens of production&#x2F;staging VPSes at previous jobs, I realized there had to be a better way for common operations I did on a daily basis than my collection of bash snippets.<p>Features:<p>- Quickly switch between different servers. Tag servers with arbitrary key values for easy search.<p>- Real-time dashboard with CPU&#x2F;memory graphs, disk usage, and uptime.<p>- Table based interface for processes (sortable&#x2F;filterable), Docker containers, systemd services, network ports, and system logs etc.<p>- Built-in file browser.<p>- Full-featured terminal when you need to drop to the command line.<p>You can check out the screenshots at <a href="https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots" rel="nofollow">https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots</a> for a quick overview of the features supported.<p>All the above are done through SSH, there are no agents&#x2F;scripts to install on your servers.<p>From using the app for a few weeks(admittedly a short duration), I can say I much prefer the ServerBuddy based workflow to my previous workflows.<p>Pricing:<p>Free forever for one server, $59 one-time for unlimited servers (includes 1 year of updates).<p>If you&#x27;re a developer or sysadmin managing Linux servers from Mac, please do try out the app. I&#x27;d love your feedback regarding additional features&#x2F;workflows etc.<p>Thank you!

[Other] Show HN: BaaS to build agents as data, not code Agents and workflows as data instead of code.<p>Julep is a backend-as-a-service to build agents and workflows. Main features:<p>1. Experimentation Velocity:<p>With most agent frameworks, agents are code that need to be deployed. To iterate on the prompts or update the agent, you need to make changes to the code and deploy it to your server. This makes agents hard to iterate on quickly. But with agents and tasks declared as data, all that happens in the background is make an api call to update or make a new entry in the database. This increases the experimentation velocity.<p>2. Scalability and long-running background tasks:<p>Scaling is a hard software engineering problem and the solution is to define large scale systems to be distributed, stateful and scalable. Agents as data is a very helpful paradigm because you have to solve for this problem only once at the orchestrator level. Julep can handle 100s of thousands of executions paralely.<p>3. Updating an agent &#x2F; User Personalization:<p>Tools such as create agent, update agent etc. can update the agent recursively. Let’s assume an agent is chatting with a user and mentions that they only like to communicate in a professional tone. The agent can call a tool to &#x27;update the agent&#x27; and modify&#x2F;update the instructions to include that the user only likes to communicate in a professional tone.<p>This was the reason to create a backend when the market was flooded with agent frameworks. In Julep, you can declare a workflow in YAML, and it can automatically scale Millions of users.

(It was also a challenge to myself to see how far I can get without referencing existing implementations)<p>Synchrotron processes nodes: simple Python classes with typed I&#x2F;O and a render() method for processing. It can be as concise as 5 lines:<p><pre><code> class IncrementNode(Node): input: StreamInput output: StreamOutput def render(self, ctx): self.out.write(self.a.read(ctx) + 1) </code></pre> Nodes can then be spawned and linked programmatically or in the graphical editor. Synchrotron handles the rest at runtime. Besides the web UI, you can also interact with the engine via Python, REST, DSL, or standalone TUI.<p>Currently you can build synths, FX chains, MIDI instruments, arpeggiators, controllers, or just mess about with sound :&gt;<p>Editor: <a href="https:&#x2F;&#x2F;synchrotron.thatother.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;synchrotron.thatother.dev&#x2F;</a> Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;ThatOtherAndrew&#x2F;Synchrotron" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ThatOtherAndrew&#x2F;Synchrotron</a><p>It&#x27;s still experimental (and my first ever shipped project), but I&#x27;d love feedback from people who tinker with audio&#x2F;DSP&#x2F;live coding.

The inspiration for Notte was to make a full-featured platform that bridges the agent reliability gap. We’ve packaged everything via a singe API for ease of use:<p>- Site Interactions - Observe website states, scrape data and execute actions<p>- Structured Output - Get data in your exact format with Pydantic models<p>- Stealth browser sessions - built-in CAPTCHA solving, proxies, and anti-detection<p>- Hybrid workflows - Combine scripting and AI agents to reduce costs and improve reliability<p>- Secrets vaults - Credential management to store emails, passwords, MFA tokens, SSO, etc.<p>- Digital personas - Digital identities with unique emails, phones for account creation workflows<p>With these tools, Notte allows you to automate difficult tasks like account creation, form filling, work on authenticated dashboards. Close compatibility with Playwright allows you to cut LLM costs and improve execution speed by mixing web automation primitives and include agents only for specific parts that require reasoning and adaptability.<p>Here’s a short YouTube demo: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=b1CzmfpdzaQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=b1CzmfpdzaQ</a><p>If any of this sounds interesting, you can run your first agent following our quickstart on GitHub <a href="https:&#x2F;&#x2F;github.com&#x2F;nottelabs&#x2F;notte" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;nottelabs&#x2F;notte</a>.

Together with contributors, we&#x27;ve been making a small template language for a year now, which, in our opinion, can replace HTMX and Alpine.js. It is a mix between EJS and Handlebars, that is, you can make a request with a familiar syntax to the server in HTML right in the markup.<p>Requests are made via fetch and are configured via javascript almost entirely, which is what is needed today to work with the server.<p>The very essence of the template language comes down to minimizing the size of the bundle of the original web application by moving the components to the server and then storing them there. Thus, on the client we get a framework, where we insert components from the server brick by brick.<p>We showed this template language a long time ago, but it was not so mature then, so people had a lot of questions: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41204552">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41204552</a><p>Thank you very much to everyone for your attention!

The agent lets you then click on HTML Elements in your app, enter prompts like &#x27;increase the height here&#x27; and will implement the changes in your source code.<p>Before stagewise, we were building a vertical SaaS for logistics from scratch and loved using prototyping tools like v0 or lovable to get to the first version. But when switching from v0&#x2F; lovable to Cursor for local development, we felt like the frontend magic was gone. So, we decided to build stagewise to bring that same magic to local development.<p>The first version of stagewise just forwarded a prompt with browser context to existing IDEs and agents (Cursor, Cline, ..) and went viral on X after we open sourced it. However, the APIs of existing coding agents were very limiting, so we figured that building our own agent would unlock the full potential of stagewise.<p>Here&#x27;s how it works: When you run `npx stagewise`, our cli proxies your running web application in dev mode and injects a toolbar containing the coding agent on top of it. Each prompt you send will be enriched with browser context and sent to our cli, which will call our backend and modify the source code of your local codebase accordingly.<p>Here&#x27;s a demo of our agent changing the login UI of Cal.com, a popular open-source meeting scheduling app: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=BkDcAozK9L4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=BkDcAozK9L4</a>.<p>So far, we&#x27;ve seen great adoption from non-technical users who wanted to continue building their lovable prototype locally. We personally use the agent almost daily to make changes to our landing page and to build the UI of new features on our console (<a href="https:&#x2F;&#x2F;console.stagewise.io">https:&#x2F;&#x2F;console.stagewise.io</a>).<p>If you have an app running in dev mode, simply `cd` into the app directory and run `npx stagewise` - the agent should appear, ready to play with.<p>We&#x27;re very excited to hear your feedback!

[Other] Show HN: Using DSPy to enrich a dataset of the Nobel laureate network I&#x27;ve been working a fair bit with DSPy lately, and I did some work in combining the benefits of vector search and LLMs (via a DSPy pipeline) to disambiguate records with a high degree of accuracy to help enrich a dataset. The blog post shows how this approach scales well, is very cost-effective and super concise - all it takes is &lt; 100 lines of DSPy code and it all runs async.<p>The code to reproduce is in this repo if anyone&#x27;s interested (all tools are 100% free and open source, and the methodology will work with open weight LLMs too). <a href="https:&#x2F;&#x2F;github.com&#x2F;kuzudb&#x2F;dspy-kuzu-demo" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;kuzudb&#x2F;dspy-kuzu-demo</a>

[Other] Show HN: FFlags – Feature flags as code, served from the edge Hi HN,<p>I&#x27;m the creator of FFlags. I built this because I wanted a feature flagging system that gave me the performance and reliability of an enterprise-scale solution without the months of dev time or the vendor lock-in.<p>The core ideas are:<p>1. Feature Flags as Code: You define your flag logic in TypeScript. This lets you write complex rules, which felt more natural as a developer myself than using a complex UI for logic.<p>2. Open Standard: The platform is built on the OpenFeature standard (specifically the Remote Evaluation Protocol). The goal is to avoid vendor lock-in and the usual enterprise slop. You&#x27;re not tied to my platform if you want to move.<p>3. Performance: It uses an edge network to serve the flags, which keeps the wall-time latency low (sub-25ms) for globally distributed applications.<p>I was trying to avoid the heavy cost and complexity of existing enterprise tools while still getting better performance than a simple self-hosted solution.<p>There&#x27;s a generous free tier ($39 per million requests after that, with no flag&#x2F;user limits). I&#x27;m looking for feedback on the developer experience, the &quot;flags-as-code&quot; approach, and any technical questions you might have.<p>Thanks for taking a look.

[Other] Show HN: Structured Cooperation – A new way of building distributed apps & POC Hey HN,<p>I wanted to share something I&#x27;ve been working on for the past couple of months, which may be interesting to developers interacting with distributed architectures (e.g., microservices).<p>I&#x27;m a backend developer, and in my 9-5 job last year, we started building a distributed app - by that, I mean two or more services communicating via some sort of messaging system, like Kafka. This was my first foray into distributed systems. Having been exposed to structured concurrency by Nathan J. Smith&#x27;s beautiful article on the subject (<a href="https:&#x2F;&#x2F;vorpus.org&#x2F;blog&#x2F;notes-on-structured-concurrency-or-go-statement-considered-harmful" rel="nofollow">https:&#x2F;&#x2F;vorpus.org&#x2F;blog&#x2F;notes-on-structured-concurrency-or-g...</a>), I started noticing the similarities between the challenges of this message-based communication, and that of concurrent programming, and GOTO-based programming before that - actions at a distance, non-trivial tracing of failures, synchronization issues, etc. I started suspecting that if the symptoms were similar, maybe the root cause, and therefore the solution, could be as well.<p>This led me to design something I&#x27;m calling &quot;structured cooperation&quot;, which is basically what you get when you apply the principles of structured concurrency to distributed systems. It&#x27;s something like a &quot;protocol&quot;, in the sense that it&#x27;s basically a set of rules, and not tied to any particular language or framework. As it turns out, obeying those rules has some pretty powerful consequences, including:<p>- Pretty much eliminates race conditions caused by eventual consistency<p>- Allows you to recover something resembling distributed exceptions - stack traces and the equivalent of stack unwinding, but across service boundaries<p>- Makes it much easier to reason about the system as a whole<p>I put together three articles that explain:<p>1) what structured cooperation is (<a href="https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;introducing-structured-cooperation&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;introducing-structured-cooperat...</a>),<p>2) one way you could implement it (<a href="https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;implementing-structured-cooperation&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;implementing-structured-coopera...</a>), and<p>3) why it works (<a href="https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;framing-structured-cooperation&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.porn&#x2F;posts&#x2F;framing-structured-cooperation&#x2F;</a>).<p>I also put together a heavily documented POC implementation in Kotlin, called Scoop (linked in the title). I guess you could call it an orchestration library, similar to e.g. Temporal (<a href="https:&#x2F;&#x2F;temporal.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;temporal.io&#x2F;</a>), although I want to stress that it&#x27;s just a POC, and not meant for production use.<p>I was hoping to bounce this idea off the community and see what people think. If it turns out to be a useful way of doing things, I&#x27;d try and drive the implementation of something similar in existing libraries (e.g. the aforementioned Temporal, Axon (<a href="https:&#x2F;&#x2F;www.axoniq.io&#x2F;products&#x2F;axon-framework" rel="nofollow">https:&#x2F;&#x2F;www.axoniq.io&#x2F;products&#x2F;axon-framework</a>), etc. - let me know if you know of others where this would make sense). As I mention in the articles, due to the heterogeneous nature of the technological landscape, I&#x27;m not sure it&#x27;s a good idea to actually try to build a library, in the same way as it wouldn&#x27;t make sense to do a &quot;structured concurrency library&quot;, since there are many ways that &quot;concurrency&quot; is implemented. Rather, I tried to build something like a &quot;reference implementation&quot; that other people can use as a stepping stone to build their own implementations.<p>Above and beyond that, I think that this has educational value as well, and I did my best to make everything as understandable as possible. Some things I think are interesting:<p>- Implementation of distributed coroutines on top of Postgres<p>- Has both reactive and blocking implementation, so can be used as a learning resource for people new to reactive<p>- I documented various interesting issues that arise when you use Postgres as an MQ (see, in particular, <a href="https:&#x2F;&#x2F;github.com&#x2F;gabrielshanahan&#x2F;scoop&#x2F;blob&#x2F;09db323bf6c8a72ca34b50392928db13f80dcc15&#x2F;src&#x2F;main&#x2F;resources&#x2F;db&#x2F;migration&#x2F;V2__create_message_event_table.sql#L20">https:&#x2F;&#x2F;github.com&#x2F;gabrielshanahan&#x2F;scoop&#x2F;blob&#x2F;09db323bf6c8a7...</a> and <a href="https:&#x2F;&#x2F;github.com&#x2F;gabrielshanahan&#x2F;scoop&#x2F;blob&#x2F;09db323bf6c8a72ca34b50392928db13f80dcc15&#x2F;src&#x2F;main&#x2F;kotlin&#x2F;io&#x2F;github&#x2F;gabrielshanahan&#x2F;scoop&#x2F;blocking&#x2F;coroutine&#x2F;structuredcooperation&#x2F;MessageEventRepository.kt#L676">https:&#x2F;&#x2F;github.com&#x2F;gabrielshanahan&#x2F;scoop&#x2F;blob&#x2F;09db323bf6c8a7...</a>)<p>Let me know what you think.
