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…
