Koji is an RPM-based build system. The Fedora Project uses Koji for their build system, as do several other projects.

Koji's goal is to provide a flexible, secure, and reproducible way to build software.

Key features:

• New buildroot for each build
• Robust XML-RPC APIs for easy integration with other tools
• Web interface with SSL and Kerberos authentication
• Thin, portable command line client
• Users can create local buildroots
• Buildroot contents are tracked in the database
• Versioned data

• Comments, questions, bugs, feedback, ideas, help requests? We'd love to hear from you.
• Mailing lists:
  • Development: koji-devel AT lists.fedorahosted.org
  • User discussion and Fedora-specific topics: buildsys AT lists.fedoraproject.org
• IRC chat: #koji on irc.freenode.net

If you have found a bug or would like to request a new feature, please report an issue in Pagure.
