ChromeOS

Chrome OS is an operating system developed by Google. Based on Gentoo and the Google Chrome web browser, it uses the Linux kernel and was designed to be a fast and lightweight operating system. Chrome OS runs mainly on web applications, although native applications are also supported.

Availability
Chrome OS was developed mainly for Chromebooks, as well as Chromeboxes, Chromebases and Chromebits. On 15 February 2022, a distribution of Chrome OS which can be installed on computers without Chrome OS pre-installed, Chrome OS Flex, entered early access in the Dev channel. A Chrome OS recovery image can also be installed onto a generic x86 device through unofficial means.

Chromium OS, the open-source equivalent of Chrome OS, can be compiled to run on computers other than those with Chrome OS pre-installed.
