openSUSE is a family of free Linux operating systems for desktops, servers and containers. Leap is the stable release and Tumbleweed the rolling release. There are also Leap Micro and MicroOS (immutable systems for servers), Slowroll, and the experimental Kalpa with KDE. The project also provides development infrastructure such as the Open Build Service and openQA. openSUSE is free to use, with no mandatory account, and is installed and managed by you on your own hardware or virtual machines.
openSUSE is open source, mainly under the GNU GPL. The project is sponsored by SUSE and, according to Wikipedia, is legally independent of that company. Leap shares its base with SUSE Linux Enterprise. SUSE is based in Luxembourg and owned through investment funds of the Swedish firm EQT. Because the distribution is fully open and runs locally, a European organisation keeps control over its data and configuration. Governance of the project, its repositories and its build infrastructure does, however, rest with a community that has a commercial main sponsor.
