License

Orbi is dual-licensed: you choose either license.
  • AGPL-3.0 — Orbi is open source under the GNU Affero General Public License v3.0. The verbatim GNU text is the repository root LICENSE. Anyone who offers a modified Orbi as a network service must publish their modifications.
  • Sustainable Use License (SUL) v1.0 — reproduced in full below, kept for users whose policies forbid AGPL.
Copyright 2026 xqliu. Self-hosting Orbi on your own repositories is free under either license. In practice, under the SUL:
  • Running Orbi on your own repositories is free, forever — for yourself, and inside a company of any size. Modify it, self-host it, run it on a thousand repos; none of that needs a license from us.
  • You may share it, as long as you do so free of charge and for non-commercial purposes.
  • You need a commercial license only if you sell Orbi itself — hosting it as a service for your own customers, or embedding it in a product you charge for.
If you are unsure which side of that line your use falls on, open a discussion at https://github.com/orbi-build/orbi/discussions and we will answer plainly. The summary above is a convenience, not a substitute. The license text below is what governs.
