Chromium OS

Chromium OS is an open-source operating system designed for running web applications and browsing the World Wide Web. It is the development version of Chrome OS, a Linux distribution made by Google.

Like Chrome OS, Chromium OS is based on the Linux kernel, but its principal user interface is the Chromium web browser rather than the Google Chrome browser. Chromium also includes the Portage package manager, which was originally developed for Gentoo Linux. Because Chromium OS and Chrome OS use a web browser engine for the user interface, they are oriented toward web applications rather than desktop applications or mobile apps.
