Hey HN, we built a Chrome Extension (https://www.magicpatterns.com/extension) that converts a snippet of any website to an isolated React component. Demo video: https://youtu.be/hutUYDkyE_A How it works: 1) Iterate through each node in the selected DOM tree, 2) For each element, find any matching CSS selectors / inline styles, 3) Use window.getComputedStyle to get the deterministic values, 4) Construct JSX It was pretty hard producing the minimal code necessary while maintaining the same visual look. To do this, we implemented things like abstracting out…

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…

Autotab is a Chrome extension that writes Selenium code to mirror your actions as you navigate the browser. See it in action: https://youtu.be/UypAcozIaoo Autotab lets you create browser automations that actually work. We designed it around two principles: 1. Show, don’t tell: In a domain like web automation, it's often easier to *show* the model what you want rather than to explain it in sentences. 2. Code is the best output: Code is easy to inspect and enables manual tweaking of the model’s suggested actions. On top of that, code output avoids lock in and is straightforward…

I needed a way to let users write JavaScript to create plugins for a site I'm building. I couldn't find a solution I was happy with, so ended up building one that run's it in a web worker on a separate domain from your main site. Hopefully I haven't missed anything. If so, please let me know! My website has an interactive demo you can write code in the browser textarea, and see the output on the right.

I’ve been experimenting with embedding an Claude Code/Cursor-style coding agent directly into the browser. At a high level, the agent generates and maintains userscripts and CSS that are re-applied on page load. Rather than just editing DOM via JS in console the agent is treating the page, and the DOM as a file. The models are often trained in RL sandboxes with full access to the filesystem and bash, so they are really good at using it. So to make the agent behave well, I've simulated this environment. The whole state of a page and scripts is implemented as a virtual filesystem hacked…
