React Developer Tools is a powerful Chrome extension that helps debug your React app. It analyzes your app's component tree structure along with the state and props of your components and provides a detailed analysis of each component's performance and rendering times.

Developed by Meta, the company behind the React library itself, this extension is a practical addition to your React workflow in a variety of scenarios:

  • Debugging your React app and verifying that a component is receiving the correct props and holding the correct state
  • Identifying the root cause of performance issues when some components are rendering slowly
  • Inspecting the context values passed to each of your components and checking that the global state is being correctly shared between them

If you're curious about how you can start using React DevTools to debug your app and improve its performance, this guide is for you. The article first looks at React DevTools in a little more detail and then demonstrates its utility through an example app.
