Open Build Service

The Open Build Service (OBS) is a generic system to build and distribute binary packages from sources in an automatic, consistent and reproducible way. You can release packages as well as updates, add-ons, appliances and entire distributions for a wide range of operating systems and hardware architectures. More information can be found on

The OBS consists of a backend and a frontend. The backend implements all the core functionality (i.e. building packages). The frontend provides a web application and XML API for interacting with the backend. Additionally there is a command line client (osc) for the API which is developed in a separate repository.


The Open Build Service is Free Software and is released under the terms of the GPL, except where noted. Additionally, 3rd-party content (like, but not exclusively, the webui icon theme) may be released under a different license. Please check the respective files for details.


You can discuss with the OBS Team via IRC on the channel #opensuse-buildservice. Or you can use our mailing list

Development / Contribution

Source Code Repository Layout

The OBS source code repository is hosted on Github and organized like this:

    dist          Files relevant for our distribution packages
    docs          Documentation, examples and schema files
    src/api       Rails app (Ruby on Rails)
    src/backend   Backend code (Perl)


There are 3 scenarios for which you can setup an OBS instance.

  1. Use the OBS appliance

    To run the OBS in production we recommend using our OBS appliance which is the whole package: a recent and stable Linux Operating System (openSUSE) bundled and pre-configured with all the server and OBS components you need to get going.

  2. Install packages and run the setup wizard

    This installation method is recommended if you have some special needs for your setup (e.g. different partition schema, SLES as base system, etc.).

    After finishing the installation of your base system, follow the following steps:

    1. Add the OBS software repository with zypper

      Please be aware, that the needed URL might differ, depending on your Operating System. (We use openSUSE Leap 42.1 in this example)

      zypper ar -f
      zypper in obs-api obs-server
    2. Run our setup wizard

  3. Install packages and configure your system manually

    If you have a more complex setup (e.g. a distributed backend) we recommend to follow our Manual Setup Guide
