React Scan is a drop-in tool that automatically detects and visually highlights React component performance issues, such as unnecessary re-renders, with no code changes required. It installs via npm or a script tag and provides an on-page toolbar for inspecting which components need optimization.

Use cases

• find why my react component re-renders too often
• detect react performance issues in my app
• visualize unnecessary re-renders in react
• profile react rendering performance without code changes
• optimize slow react app rendering
• debug react re-render problems

When to choose

• you want zero-config React performance detection with visual highlighting
• you use React, Next.js, Vite, or Remix and need quick re-render diagnostics
• you prefer a drop-in script or npm package over heavy profiling setups

When to avoid

• you are not using React or React DOM
• you need full application performance monitoring beyond rendering
• you want static analysis or agent-integrated checks - the maintainers now recommend React Doctor for that
