# Kyno licensing

Kyno uses two licenses. The idea behind the split is simple: the parts you
integrate with are yours to copy, and the control plane is free to run but
not to resell.

These directories are under the MIT license. They are the integration
surface, and we want people to copy them, fork them, and build better
adapters on top of them:

- src/kyno/sdk/
- src/kyno/adapters/
- src/kyno/conformance/
- conformance/
- docs/integrating.md

Everything else is under the Elastic License 2.0. That covers the control
plane: the server, the store, the CLI, and the publishing pages. You can
read it, change it, and self-host it in production for free, including
commercially. The one thing you cannot do is offer Kyno itself to third
parties as a hosted or managed service.

To know which license applies to a file, look at its first line: files
that begin with an MIT header are MIT, and everything else in this
repository is under the Elastic License 2.0. The full texts are in the
LICENSES directory.
