Why it's a strong pick

Redux DevTools shows you every action your Redux app fires and the state that follows. It is open source under the MIT license, and its code is public on GitHub. It uses Manifest V3, Chrome's current extension format. Its code was last changed on 20 September 2026.

What it does

Redux DevTools adds a panel to Chrome DevTools. You see each action, the state before and after it, and you can step back and forth through them. It is built for Redux, and it can also work with other state setups that connect to it.

Key features

Action and state inspector. See what was dispatched and how state changed.
Time-travel debugging. Move back and forward through past states.
Action replay. Run actions again to see the result.
Hot reloading. Keep working while your code reloads.
Remote monitoring. Watch state from an app running somewhere else.

Who it's for

Redux DevTools is for front-end developers who use Redux or Redux Toolkit. If your app does not use Redux, or another state setup that connects to it, this extension has nothing to show you.

What permissions does Redux DevTools ask for?

Its manifest asks for notifications, contextMenus and storage. It lists access to file, http and https sites, runs content scripts on all pages except Google domains, and adds a DevTools page. We could not read the developer's privacy policy when we checked; read it before installing.

Does my app need setup before it works?

Yes. The README says the app needs Redux 3.1.0 or newer with the devtools enhancer set up. Installing the extension alone shows nothing. Follow the setup steps in the project's README, then reload your app and open the Redux DevTools panel.

Is it safe to turn on in production?

The README advises caution about enabling it in production builds. Keep it on for development. Before you ship a release, check how your store is configured so the devtools hook is not left on for every visitor to your site. When in doubt, test a production build.

FAQ

Does it only work with Redux? It is built for Redux. The README says other state setups can work if they integrate with it.

Is it open source? Yes, under the MIT license.

Can I debug an app on my own computer? Yes, but it needs access to all sites, including local file and http pages, to work on any local app.

Good to know

Set up the enhancer first, then install the extension. If the panel is empty, the cause is almost always the app setup, not the extension. Also remember that the access it asks for is wide, so keep it for development work.
