   Chunk – Code sandbox for back-end devs▲96

   Chunk co-founder here. We spent the last 2 weeks building this to scratch our own itch: As developers, we often have problems that could be solved just by running a few lines of code. Sometimes, running this code on your local machine is fine. But other time, the code need to run automatically reacting to external events or to run continuously, which means, it needs to run on a server somewhere. So now, you have to find a cloud provider, to package or build the code and finally to deploy it. All of that for what could be literally be 4 lines of code. We couldn’t find an easier way to do…

   ChunkHound, a local-first tool for understanding large codebases▲114

   ChunkHound’s goal is simple: local-first codebase intelligence that helps you pull deep, core-dev-level insights on demand, generate always-up-to-date docs, and scale from small repos to enterprise monorepos — while staying free + open source and provider-agnostic (VoyageAI / OpenAI / Qwen3, Anthropic / OpenAI / Gemini / Grok, and more). I’d love your feedback — and if you have, thank you for being part of the journey!

   ScrapScript – A tiny functional language for sharable software▲503

   Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

   Chunk▲298

   Hi HN Dudley here, tech lead on Chunk. Chunk is a macOS menu bar app for time-blocking. It opens with Cmd + / and slides down over whatever you're doing - including fullscreen apps. There's also a live countdown in the tray for the current block. Click-and-drag to create blocks, day/week views, Google/Outlook/Apple Calendar sync, Apple Reminders integration, and a Todo mode where tasks can be dragged onto the timeline. Templates and Routines let you build an ideal day once and auto-apply it on chosen weekdays. There's a local MCP server, so you can ask Claude Desktop to…

   Context.dev▲814

   Hello, My name is Yahia, I've been working on scraping products for a long time and maintain a couple of free sites in my spare time (E.g. knifegeek.io) What prompted this is i've rebuilt scraping infra at every company I've started and finally just made it a product. Pass a URL, get clean markdown, html, images, sitemap or pass a domain, get logos, colors, socials, industry data. Goal is to offer a better service than VC funded competitors at a fraction of the cost. Stealth is included and automatic at no additional cost (normally an upcharge by alternatives). Would love your honest thoughts.

    Ultra-lightweight chunker library with emoji support▲19

    I kept rewriting the same array.slice(i, i + n) logic in every project. Eventually, I decided to stop and just make a utility. Chonkify is a small (~870B), zero-dependency JS/TS library for chunking any kind of data: - Works with Array, String, Buffer, Set, Map, Array-like, TypedArray - Handles AsyncIterable (great for batching streams) - Unicode-safe (correctly handles grapheme clusters, emoji, etc.) - ESM-first, TypeScript-ready I mostly made it for myself, but figured others might find it useful too. Would love feedback!

    A JavaScript library for data visualization in both SVG and Canvas▲161

    Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support. I am aware there are already libraries that can draw to multiple contexts interchangeably, but I've added a few little niceties to Ripl that (as far as I know) some other libraries don't have such as CSS-like query selectors, DOM-like…
