ChromiumOS (formerly styled as Chromium OS) is a free and open-source Linux distribution designed for running web applications and browsing the World Wide Web. It is the open-source version of ChromeOS, a Linux distribution made by Google.

ChromiumOS is based on the Linux kernel, like ChromeOS, but its principal user interface is the Chromium web browser rather than the Google Chrome browser. ChromiumOS also includes the Portage package manager, which was originally developed for Gentoo Linux.^[4] Because ChromiumOS and ChromeOS use a browser engine for the user interface, they are oriented toward web applications rather than application software or mobile apps.^[5]

Google first published the ChromiumOS source code in late 2009.^[6]
