Hey HN, we're excited to have people try out our framework! When we built out a Chrome extension earlier this year, we noticed that the config was too imperative. You had to constantly tell Chrome via the manifest.json file where your files were, what your permissions should be, etc. So we thought it might be interesting to build a more declarative framework. When we built a proof of concept, we enjoyed working with it and decided to invest more time into making it usable and adding more features. We're still pretty early in building it out, and there's a bunch more we want to add, but this…

Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

Hey HN, I'm David, one of the creators of Shipper. My brother and I made this tool that builds full-stack software from a few prompts, so it's like talking to ChatGPT. Its purpose is to help you go from idea to product without starting from scratch. There are other no-code builders out there but they either require a technical background or become unreliable for long term projects (e.g. they lose context and break your project). Shipper writes code for you and asks for technical knowledge only if you're comfortable with it. Technical details: I think you could also call it a vibe coding tool…

FavBox▲65Hi HN, I am working on a small side project called FavBox. It is a local-first browser extension that extends your existing bookmarks. It builds on your browser’s native bookmarks instead of replacing them or changing your default workflow. Key features: syncs with your browser profile, no third-party data sharing, no ads. no tracking. Clean, minimalist UI with tags support.

Live extension analysis: Point us at a Chrome/Edge/Firefox extension (store URL or CRX). We spin up a safe sandbox and observe it in real time—permissions use, message passing, storage writes, network calls, remote code loading, and UI injections. Package scanning: Paste an npm/package URL or code. We do quick static + dynamic checks: install/postinstall scripts, obfuscation/eval, exfil endpoints, suspicious APIs, and typosquat/reputation signals. AI explainer: An LLM summarizes the behaviors and risk patterns in plain English (why it’s risky, what to verify,…
