postmarketOS (abbreviated as pmOS) is an operating system primarily for smartphones, based on the Alpine Linux distribution. Developed since 2016, it was launched in 2017, and continues to be a work in progress.
It is capable of running different X and Wayland based user interfaces, such as Plasma Mobile, MATE, GNOME, and XFCE; later updates added support for Unity8 and Phosh. It is also capable of running Docker, if the device specific kernel has cgroups and relevant configs enabled. The project aims to provide a ten-year lifecycle for smartphones.
