Zorin OS is a Linux distribution based on Ubuntu with both free and paid versions.

The desktop environment themes can resemble those of Microsoft Windows, macOS, or Ubuntu[7][8][9] and allow the interface to be familiar regardless of the previous system a user has come from.

[10] In January 2020, the developers announced plans to release Zorin Grid, which would be software for installing and maintaining Zorin OS within a network, aimed at companies and schools.

[13] The project was started in 2008 by co-founders Artyom and Kyrill Zorin.

Since version 16.3, the system's upgrade tool can be used to upgrade existing installations; earlier versions required users to do a clean install.
