[CLI Tool] Show HN: OWhisper – Ollama for realtime speech-to-text Hello everyone. This is Yujong from the Hyprnote team (<a href="https:&#x2F;&#x2F;github.com&#x2F;fastrepl&#x2F;hyprnote" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;fastrepl&#x2F;hyprnote</a>).<p>We built OWhisper for 2 reasons: (Also outlined in <a href="https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;what-is-this" rel="nofollow">https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;what-is-this</a>)<p>(1). While working with on-device, realtime speech-to-text, we found there isn&#x27;t tooling that exists to download &#x2F; run the model in a practical way.<p>(2). Also, we got frequent requests to provide a way to plug in custom STT endpoints to the Hyprnote desktop app, just like doing it with OpenAI-compatible LLM endpoints.<p>The (2) part is still kind of WIP, but we spent some time writing docs so you&#x27;ll get a good idea of what it will look like if you skim through them.<p>For (1) - You can try it now. (<a href="https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;cli&#x2F;get-started" rel="nofollow">https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;cli&#x2F;get-started</a>)<p><pre><code> bash brew tap fastrepl&#x2F;hyprnote &amp;&amp; brew install owhisper owhisper pull whisper-cpp-base-q8-en owhisper run whisper-cpp-base-q8-en </code></pre> If you&#x27;re tired of Whisper, we also support Moonshine :) Give it a shot (owhisper pull moonshine-onnx-base-q8)<p>We&#x27;re here and looking forward to your comments!

[API/SDK] Show HN: I built a free alternative to Adobe Acrobat PDF viewer I built EmbedPDF: an MIT-licensed, open-source PDF viewer that aims to match all of Adobe Acrobat’s paid features… for free.<p>Already working:<p>- Annotations (highlight, sticky notes, free text, ink)<p>- True redaction (content actually removed)<p>- Search, text selection, zoom, rotation<p>- Runs fully in the browser, no server needed<p>- Drop-in SDK for React, Vue, Preact, vanilla JS<p>Why? Acrobat is heavy, closed, and pricey. I wanted something lightweight, hackable, and embeddable anywhere.<p>Demo: <a href="https:&#x2F;&#x2F;app.embedpdf.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;app.embedpdf.com&#x2F;</a> Website: <a href="https:&#x2F;&#x2F;www.embedpdf.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.embedpdf.com&#x2F;</a> GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;embedpdf&#x2F;embed-pdf-viewer" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;embedpdf&#x2F;embed-pdf-viewer</a><p>Feedback, bug reports, and feature requests welcome!

[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: Turn your iPhone into a local OCR server using Vision Framework Built an iOS app that runs a local OCR server using Apple&#x27;s Vision Framework.<p>Creates a REST API endpoint accessible from any device on your network. No cloud services needed - everything processes locally on the phone.<p>Available on App Store (searching &quot;OCR Server&quot;).<p>Would appreciate feedback on the architecture or similar mobile-as-server projects you&#x27;ve seen.

[Other] Show HN: Created 60 free useful tools in one place Hey there, I&#x27;m a solo dev behind KewlTools.<p>So I&#x27;m one of those people who like to build their own tools&#x2F;utilities whenever they a) want to get something done, or b) want to learn something. c) don&#x27;t want to spend ages finding a utilty and going through walls of ads.<p>I gradually built 66 tools, all free, fast, ad-free, and zero login.<p>I (and my family&#x2F;friends) use these daily, so thought some of you will find it useful!<p>Any suggestions, improving current tools or adding new ones, please let me know.

[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: Enter your domain and my open-source agent will hack it I built an open-source AI agent for security testing to find and fix vulnerabilities in your code.<p>I’ve noticed how bad security vulnerabilities have gotten with everyone shipping AI code slop, so I wanted to build something that allows for vibe-coding at full speed without compromising security.<p>Traditional security tools aren’t effective, and manual pen-testing can’t keep up with the rapidly growing AI code<p>This tool runs your code dynamically, finds vulnerabilities, and validates them through actual exploitation.<p>You can either run it against your codebase or enter your (or someone else’s) domain to scan for vulnerabilities.<p>Good luck, have fun, hack responsibly!

[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!

[Other] Show HN: ServerBuddy – GUI SSH client for managing Linux servers from macOS Hi HN,<p>I&#x27;ve built an app for macOS that allows performing common SSH operations on Linux servers using a native GUI.<p>The problem:<p>Managing multiple Linux servers usually means juggling terminal windows and copy-pasting snippets&#x2F;scripts. 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: An open-source email archiver with full-text search capabilities Hey HN,<p>I’d like to share an open-source project I’ve created. It is an email archiving tool that can back up your whole email system with full-text search capabilities.<p>The project is called Open Archiver, and it is able to archive and index emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and any IMAP-enabled email inbox. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage).<p>Some features:<p>- Archive and index all emails and attachments<p>- Import and sync the whole organization&#x27;s emails: For Google Workspace and MS 365, Open Archiver can ingest all individual inboxes&#x27; emails<p>- PST and .eml files import<p>- Role-based access<p>- Full-text search: All archived emails and attachments are indexed, so you can search the content of all emails and attachments<p>- You can choose to store your files either on your local machine or on any S3-compatible storage provider<p>- API access<p>It&#x27;s AGPL-3.0 licensed and free to use for personal and business purposes. I&#x27;d be happy if you could give it a try and give me some feedback.<p>You can find the project on GitHub (with Demo site): <a href="https:&#x2F;&#x2F;github.com&#x2F;LogicLabs-OU&#x2F;OpenArchiver" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;LogicLabs-OU&#x2F;OpenArchiver</a>
