Want the open-source browser that Chrome, Edge and many others are built on? Chromium gives you a browser and a development toolset in one Windows program. The Chromium project also publishes source code and build guidance for developers who want to inspect or work on the browser itself.
Browse with tabs and the omnibox
Chromium handles everyday browsing with a tab bar, an address bar that accepts web addresses or searches, and familiar tools such as bookmarks, browsing history, and downloads. Open pages in separate tabs to keep several sites available in one window, then return to saved bookmarks or previously visited pages.
Google Chrome is built from Chromium's code, but Chromium itself is a separate, fully open-source browser.
Inspect web pages in DevTools
Chromium's developer tools let you examine a page while it is open. Inspect the document structure and styles, run JavaScript in the console, and look at network activity such as page requests. These tools support hands-on debugging when a site or web app does not behave as expected.
Build or contribute to Chromium
The Chromium project provides documentation for browsing its source, checking out the code, building and running it, and contributing changes. Developers can also find guidance for debugging, testing, and reporting bugs.
- Browse or search the source code online.
- Follow the project’s checkout, build, and run guidance to work locally.
- Use project documentation for testing, debugging, and bug reports.
Pros
- DevTools can inspect page structure, scripts, and network activity
- Tabbed browsing, an address bar, bookmarks, and history handle everyday browsing
- The open-source project provides a source checkout and build workflow
