Chrome is built on [Chromium](https://www.chromium.org/), an open-source web
browser project. You can
[download and run Chromium](https://www.chromium.org/getting-involved/download-chromium/)
as a standalone browser.

Chrome adds some important features on top of Chromium.

For example:

- Chrome adds proprietary software for decoding audio and video files, known as codecs.
- Chrome can report errors to its engineering team if the user permits.
- Chrome provides a number of user-agent features such as password management, shared history, bookmarks and more, using your Google Account.
- Chrome downloads updates automatically.
- Chrome implements Chrome DevTools for testing, debugging and experimenting right in the browser.

Chrome also goes through rigorous additional testing processes through its
[release channels](https://developer.chrome.com/docs/web-platform/chrome-release-channels). This includes
Chrome Canary, Chrome Dev, Chrome Beta, and Chrome Stable.

To get an idea of just how much effort goes into building a browser, take a
look at the `chrome://credits page`. It lists hundreds of technologies
and projects used by Chrome.

## Other browsers and Chromium

Chromium's codebase is used for more than just Google Chrome. The code is the
basis of many other browsers, including Microsoft Edge, Samsung Internet, Arc,
[Android WebView](https://developer.android.com/develop/ui/views/layout/webapps),
Vivaldi, Brave, and Opera.
