As a developer working with the open-source React JavaScript library, having a powerful tool to inspect and analyze React component hierarchies is essential. This is where the React Developer Tools Chrome extension comes into play. With a total rating of 4.058001397624039, this extension has proven to be a valuable asset for React developers worldwide.
Upon installing the React Developer Tools Chrome extension, you'll find two new tabs in your Chrome DevTools: "⚛️ Components" and "⚛️ Profiler". These tabs provide essential functionalities to enhance your React development workflow.
Inspect and Analyze Components
The "⚛️ Components" tab allows you to explore the React component tree rendered on the page. It provides a comprehensive view of the root React components, as well as their corresponding subcomponents. By selecting a component in the tree, you can delve into its current props and state, enabling you to debug and make necessary changes directly in the panel on the right. Additionally, the breadcrumbs feature allows you to navigate through the chain of component creation, gaining insights into the relationships between different components.
Moreover, if you inspect a React element using the regular Elements tab, you can seamlessly switch to the React tab, and the corresponding element will be automatically selected in the React tree. This integration ensures a smooth and efficient development experience.
The "⚛️ Profiler" tab is a game-changer when it comes to optimizing the performance of your React applications. With this tab, you can record performance information and identify bottlenecks in your code. By analyzing the collected data, you can make informed decisions to optimize your application's performance and deliver a seamless user experience.
While React Developer Tools is a Chrome extension, it does not compromise your privacy. It requires permissions to access the page's React tree, but it does not transmit any data remotely. Furthermore, being fully open-source, you can explore and contribute to its development by accessing the source code at https://github.com/facebook/react/tree/master/packages/react-devtools-extensions.
Don't just take my word for it! Let's hear what other developers have to say:

- Yerko Antonio Medina Pichún: "Antes funcionaba super bien, ahora ya no aparece."
- Alex Zander: "Cannot use on Dev page defeats all purpose. Like it."
- Abhishek Jaiswal: "After installing the extension, I am facing this error... 'This page doesn’t appear to be using React. If this seems wrong, follow the troubleshooting instructions.' What should I do next?"
- Andric Alfaro: "No me aparece."
- Muhammad Mudassar: "From the last two days, I am facing an error of Dev tools failed in Chrome. I have tried reinstalling this extension, but still, the issue didn't resolve."
- Cole Nelson: "It can be flakey sometimes, but if you reload the page or recompile your project, it fixes itself. It's very handy! If you build in React, then this is a MUST!"
- Javier Melero: "It's useless... it's freezing every time with 'timed out' errors, it doesn't provide useful information, seeing things like 'state... state.. state.. Effect: f().. .Callback..' does not help. I don't know, after so many years, it didn't evolve at all. Take a look at Vue Dev Tools, they are years ahead of this."

This tool is very helpful to me as a beginner web developer and i enjoy to work with it.it's great.
a nice tool. it makes debugging easy.
If it doesn't work: don't forget to close and reopen your browser!
very very useful tool
it's good but i am facing a problem when i am using React.memo(...) the component which are not re-rendering also showing highlight why ?
Worked :)
Good One
For those saying the tabs aren't appearing, you have to tinker with it a bit. I closed the inspect window and reopened it. After that, the tabs popped up for me.
no components tab :/
component tab doesn't exist
For anyone who's having issues with the console tabs not appearing: Press F12 to open your console, click the gear/cog icon to open the console settings, then in the bottom right there's a button that says "Restore defaults and reload". This should bring the console tabs back if they're missing. Invaluable extension.
Great as always. To make it work with vite/chrome, I had to turn off Application/Service workers/Update on reload. (https://github.com/facebook/react/issues/24094)
Doesn't work (with Vite) in Chrome BUT works with Arc browser on the same web-app :)
