Chromium is a free and open-source web browser developed by Google. It is a fully functional browser on its own and supplies the vast majority of source code for the Google Chrome browser. The two browsers have always had some differences, as indicated by their names: chromium is the metal used to make chrome plating.[6]
The Chromium source code is also widely used by other parties to create their own browsers, in a similar manner as Google, while others simply build it as-is and release browsers with the Chromium name.
The user interface is minimalist because Google wanted its browser to "feel lightweight (cognitively and physically) and fast"
