SUSE Studio is an online Linux software creation tool by SUSE. Users can develop their own Linux OS, software appliance or virtual appliance, mainly choosing which applications and packages they want on their “custom” Linux and how it looks. Users can choose between openSUSE or SUSE Linux Enterprise as a base and pick from a variety of pre-configured images including jeOS, minimal server, GNOME and KDE desktops.
