How to install React Developer Tools

Browser extension

The easiest way to debug websites built with React is to install the React Developer Tools browser extension. It is available for several popular browsers:

Now, if you visit a website built with React, you will see the Components and Profiler panels.

Safari and other browsers

For other browsers (for example, Safari), install the react-devtools npm package:

# Yarn
yarn global add react-devtools

# Npm
npm install -g react-devtools

Next open the developer tools from the terminal:

react-devtools

Then connect your website by adding the following <script> tag to the beginning of your website’s <head>:

<html>
  <head>
    <script src="http://localhost:8097"></script>

Reload your website in the browser now to view it in developer tools.

Mobile (React Native)

To inspect apps built with React Native, you can use React Native DevTools, the built-in debugger that deeply integrates React Developer Tools. All features work identically to the browser extension, including native element highlighting and selection.

For versions of React Native earlier than 0.76, please use the standalone build of React DevTools by following the Safari and other browsers guide above.
