what is react-devtools-experimental fr?

React DevTools is a browser extension that helps developers see and debug React applications, the JavaScript framework used to build many websites. This repository is an experimental version where someone explored a completely redesigned approach to that extension. The original React DevTools extension lets developers inspect components, see their properties, and understand how data flows through an app. This experimental rewrite attempts to rebuild that tool from scratch with a new architecture and design. Think of it like redesigning a car engine: same purpose, different internal structure. The README makes clear this isn't an official project, it's more of a proof-of-concept or research effort shared openly for people interested in how the tool could work differently. To run the code yourself, you'd install its dependencies and start a local development server using standard JavaScript tools. There's also a live preview version available online if you want to see what the experimental interface looks like without setting anything up locally. Who would care about this? React developers and framework tool builders would be the main audience, people curious about how browser developer extensions work, or those thinking about better ways to debug React apps. However, the README is explicit that this is unsupported and experimental, meaning it's not ready for everyday use. It's the kind of project that might inspire ideas, get picked apart in code reviews, or eventually become the blueprint for an official redesign, but right now it's more "check out this approach" than "use this in production."
