I made a CLI tool to create web extensions with no build configuration2024 · github.com · ▲381Hello 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…

AI Chrome Extension BuilderJan 2026 · app.shipper.now · ▲239Hey 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).

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
