React Developer Tools

By: Meta
Adds React debugging tools to the Chrome Developer Tools. Created from revision 5d87cd2244 on 7/4/2025.

React Developer Tools is a powerful Chrome extension designed to enhance your React development experience. It integrates seamlessly into Chrome Developer Tools, adding two new tabs: "Components ⚛" and "Profiler ⚛". The Components tab lets you explore the root React components and their subcomponents, while enabling you to inspect and edit their current props and state directly within the panel. Additionally, selecting elements on the page automatically highlights them in the React tree, making navigation intuitive.

The Profiler tab allows developers to record and analyze performance data to optimize React applications effectively. This extension is fully open source, respects user privacy as it does not transmit data remotely, and requires permission solely to access the page's React component tree. It is an essential tool for React developers aiming to debug, profile, and improve their applications efficiently.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

React Developer Tools requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

React Developer Tools has earned a good reputation and can be trusted.
