About Redux DevTools
Redux DevTools shows what your app's state is doing. Each action you dispatch appears in a log with the state that resulted, and Mozilla's listing says you can inspect every state and action payload and go back in time by cancelling actions. It is built by the Redux team and lives in the reduxjs organisation on GitHub.
Unlike the other framework tools it does not detect your app automatically. Your code has to connect to it, usually by passing a small enhancer when you create the store. The README documents this for Redux, and links to integrations for other architectures and for non-browser apps, plus options to limit it in production. The code is MIT licensed, the Chrome build runs on Manifest V3, and the latest release came out in October 2026.
The cost is the setup and a dense interface, and its host access covers all websites, plus a notification and context menu permission. If you build with Redux, or with a library that supports the same connection, it is one of the most useful debugging tools available, and well worth the few minutes of configuration.
Pros and cons
- Shows each action and the state it produced
- Time travel debugging lets you step through state
- Open source under the MIT licence, updated October 2026
- Works with Redux and other architectures via integrations
- Needs a line of setup in your app code
- Dense interface that takes time to learn
- Only in the Chrome Web Store and on Firefox Add-ons; no Safari version
Permissions
It requests access to web pages and local files so it can connect to the store in your app, plus storage, notifications and context menu permissions.
