    Hey guys! I’ve been working on a web app called CodeCafé—a collaborative, browser-based code editor inspired by VS Code and Replit, but with no downloads, no sign-up, and zero setup. You just open the link and start coding—together. The frontend is built with React and TypeScript, and the backend runs on Java with Spring Boot, which handles real-time editing via WebSockets. For syncing changes, I’m using Redis along with a custom Operational Transformation system (no third-party libraries!!!). The idea came after I found out a local summer school was teaching coding using Google Docs (yes,…

    Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

    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…

    Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years. Deco.cx is the thing that we wish existed when we were managing hundreds of enterprise-grade React-based websites. The gist is: JSX, HTMX, TypeScript, Tailwind and Deno. All visually editable in a beautiful, collaborative,…
