What is Chromium
The best browser you’ve never heard of
Chromium is the open source project that underpins Google’s Chrome browser. Since the project is open source, both Google and others are able to build on and use the Chromium source code. In fact, anyone can download, compile, and tinker with the source code for Chromium.
As a web browser, Chromium is inherently less stable than Chrome, which means it crashes more often and can exhibit other types of undesirable behavior. However, it is compatible with Chrome browser extensions and offers a very similar user experience without submitting to any invasive information gathering from Google.
