Zalando Open Source Principles

Vision

We strongly believe that open source software benefits the tech community, and that providing broadly useful code to the world is a virtue. We strive to work in an open source way to the betterment of Zalando and the world.

Principles

  • Do “Open Source First”: If your Zalando project can also be useful to non-Zalandos, release it as open source from the start.
  • Take Ownership: Your team is responsible for ensuring that it’s possible to open source your project. Your delivery lead is available for guidance.
  • Share Your Code: All code shared between teams must be open source.
  • Be Safe: To ensure the broadest possible use of your project, use the MIT License only.
  • Deliver Quality: Provide a great out-of-the-box experience.
  • Provide Documentation: Include a clear README and default working configuration.
  • Stay Secure: Make sure your project doesn’t include Zalando specifics, such as credentials and private identifiers.
  • Ask for Help: Find colleagues to brainstorm ideas for your project and to review your work.
  • Promote: Tell the world about your project via blog posts, social media and conference talks.
  • Join the Open Source Guild: Help us make open source stronger at Zalando!
