React DevTools is a browser extension for Chrome and Firefox that lets developers inspect the React component hierarchy within the browser's Developer Tools. This repository has migrated into the main facebook/react monorepo, with v3 source preserved on the v3 branch.
Use cases
- inspect react component hierarchy in devtools
- debug react component props and state in browser
- view react component tree while developing
- profile react app performance in chrome
- find which react component renders an element
When to choose
- you develop React apps and need component-level inspection in Chrome or Firefox
- you want to debug props, state, and hierarchy of React components live in the browser
When to avoid
- you need the latest v4+ features, which live in the facebook/react monorepo
- you debug non-React frontend frameworks
- you need a standalone (non-browser) React inspector without building from the v3 branch
