"Chromium refers to a pair of open-source projects that power
the Google Chrome Web browser and Google Chrome OS. The Chromium
project's mission is to build an interface for users to experience
the Web in a way that's "faster, safer, and more stable than
existing alternatives." The Chromium OS project, on the other hand,
aims to develop a Web-focused operating system and computing
experience that's 'fast, simple, and secure.'
"Chromium browser releases are designed to run on Windows, Mac
OS X, Linux and ChromeOS operating systems. While Chromium releases
parallel those of Google Chrome releases, Chromium downloads are
distinguished from Google Chrome browser downloads by the lack of
Google's branding, the GoogleUpdate automatic updating system, an
integrated Adobe Flash Player and sandboxed PDF viewer, and usage
statistics and crash reporting options.
"The project also offers extensive documentation and source code
for developers interested in exploring and/or contributing to the
project. The Chromium project's name is derived from the element
chromium, which is the metal used to make chrome."
