vpsAdminOS is a host system for containers developed by vpsFree.cz. We use it to run our VPS.
vpsAdminOS is a spin of NixOS. The host system is rather small and includes only management services, as it focuses on running everything else in Linux system containers. vpsAdminOS is interconnected with vpsAdmin, our control panel. It is however also usable outside of vpsFree.cz's infrastructure, e.g. on your home server.
