About React Scan

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!
