[Other] Show HN: OnlyJPG – Client-Side PNG/HEIC/AVIF/PDF/etc to JPG TL;DR: private, in-browser converter that turns pretty much any image file format into standard JPEGs. Everything runs locally. No uploads.<p>This started as a five-minute job and forty hours later...<p>I wanted to convert a HEIC without uploading it anywhere, so I wrestled Emscripten&#x2F;WebAssembly to run Google&#x27;s Jpegli inside a Web Worker. Now there&#x27;s a small UI and it handles a bunch of formats.<p>Just about the only thing it can&#x27;t decode is JXL - but there&#x27;s still some JPEG XL magic in there: XYB perceptual color quantization is enabled by default via Jpegli.<p>The upside of all this over-engineering is privacy and compatibility: images are processed entirely on your machine and never touch a server; the output is a regular JPEG that works everywhere.<p>I could have used a CLI, sure — but where&#x27;s the fun in that?<p>Would love feedback on edge cases and defaults.<p>Tested on Firefox, Chrome, and Safari.<p>Cheers!

[CLI Tool] Launch HN: Inkeep (YC W23) – Open Source Agent Builder Hi HN! I&#x27;m Nick from Inkeep. We built an agent builder with true 2-way sync between code and a drag-and-drop visual editor, so devs and non-devs can collaborate on the same agents. Here’s a demo video: <a href="https:&#x2F;&#x2F;go.inkeep.com&#x2F;video">https:&#x2F;&#x2F;go.inkeep.com&#x2F;video</a>.<p>As a developer, the flow is: 1) Build AI Chat Assistants or AI Workflows with the TypeScript SDK 2) Run `inkeep push` from your CLI to publish 3)Edit agents in the visual builder (or hand off to non-technical teams) 4) Run `inkeep pull to edit in code again.<p>We built this because we wanted the accessibility of no-code workflow builders (n8n, Zapier), but the flexibility and devex of code-based agent frameworks (LangGraph, Mastra). We also wanted first-class support for chat assistants with interactive UIs, not just workflows. OpenAI got close, but you can only do a one-time export from visual builder to code and there’s vendor lock-in.<p>How I&#x27;ve used it: I bootstrapped a few agents for our marketing and sales teams, then was able to hand off so they can maintain and create their own agents. This has enabled us to adopt agents across technical and non-technical roles in our company on a single platform.<p>To try it, here’s the quickstart: <a href="https:&#x2F;&#x2F;go.inkeep.com&#x2F;quickstart">https:&#x2F;&#x2F;go.inkeep.com&#x2F;quickstart</a>.<p>We leaned on open protocols to make it easy to use agents anywhere: An MCP endpoint, so agents can be used from Cursor&#x2F;Claude&#x2F;ChatGPT A Chat UI library with interactive elements you can customize in React An API endpoint compatible with the Vercel AI SDK `useChat` hook Support for Agent2Agent (A2A) so they work with other agent ecosystems<p>We made some practical templates like a customer_support, deep_research, and docs_assistant. Deployment is easy with Vercel&#x2F;Docker with a fair-code license and there&#x27;s a traces UI and OTEL logs for observability.<p>Under the hood, we went all-in on a multi-agent architecture. Agents are made up of LLMs, MCPs, and agent-to-agent relationships. We’ve found this approach to be easier to maintain and more flexible than traditional “if&#x2F;else” approaches for complex workflows.<p>The interoperability works because the SDK and visual builder share a common underlying representation, and the Inkeep CLI bridges it with a mix of LLMs and TypeScript syntactic sugar. Details in our docs: <a href="https:&#x2F;&#x2F;docs.inkeep.com">https:&#x2F;&#x2F;docs.inkeep.com</a>.<p>We’re open to ideas and contributions! And would love to hear about your experience building agents - what works, hasn’t worked, what’s promising?

[Other] Show HN: Modshim – a new alternative to monkey-patching in Python I&#x27;ve invented a new alternative to forking &#x2F; vendoring &#x2F; monkey-patching packages in Python.<p>It&#x27;s a bit like OverlayFS for Python modules - it allows you write modifications for a target module (lower) in a new module (upper), and have these combined in a new virtual module (mount).<p>It works by rewriting imports using AST transformations, then running both the lower and upper module&#x27;s code in the new Python module.<p>This prevents polluting the global namespace when monkey-patching, and means if you want to make changes to a third-party package, you don&#x27;t have to take on the maintenance burden of forking, you can package and distribute just your changes.
