Scan React apps for performance problems

React Scan automatically detects performance issues in your React app

Previously, existing tools required lots of code change, lacked simple visual cues, and didn't have a simple, portable API

Instead, React Scan:

- Requires no code changes – just drop it in
- Highlights exactly the components you need to optimize
- Available via script tag, npm, CLI, you name it!

Very useful for react developers!

It's much more user-friendly than the React dev tools.
