The Open Build Service (OBS) is an open and complete software distribution development platform. It provides the infrastructure to create software packages for a wide range of operating systems and hardware architectures as well as add-ons, appliance images or entire linux distributions.

OBS provides the tools to work collaboratively, supporting access rights, merge requests and review functionality. Users can access OBS via a convenient web interface, as well as a commandline tool or via the extensive API.

Rather than using "compiler farms" of different hardware to build packages for different architectures and multiple Linux distributions like Fedora, Debian, Ubuntu, the OBS creates a clean virtual instance for each build, saving the user time and resources.
