## Licensing

Current CockroachDB code is licensed in three ways:

- [Business Source License (BSL)](https://www.cockroachlabs.com/docs/stable/licensing.html#bsl)
- [Cockroach Community License (Free)](https://www.cockroachlabs.com/docs/stable/licensing.html#ccl-free)
- [Cockroach Community License (Paid)](https://www.cockroachlabs.com/docs/stable/licensing.html#ccl-paid)

Core features released up to and including version 19.1 are licensed under [Apache 2.0](https://www.cockroachlabs.com/docs/stable/licensing.html#apache). After version 19.1, core features are licensed under the BSL for three years before converting to the Apache 2.0 license.

BSL features are free to use and the source code is available, but users may not use CockroachDB as a service without an agreement with Cockroach Labs. Outside of this usage, BSL features will continue to be free to use and source code will continue to be available.

[Certain core features](https://www.cockroachlabs.com/docs/stable/licensing.html#core-feature-licensing) and all enterprise features are licensed under the Cockroach Community License (CCL).

For more information, see [Licensing](https://www.cockroachlabs.com/docs/stable/licensing.html).
