CameoDB Licensing

CameoDB uses a multi-license model inspired by the Sentry licensing policy.

Our codebase is intentionally split between a permissive core, MIT-licensed SDKs, and a protected FSL-covered product surface that eventually becomes Apache-2.0.

account_tree Component Summary

Component / Path	License	Notes
Core Crates `crates/cluster`, `crates/storage`	Apache 2.0	Fully open source core with patent protection.
SDKs & Client Tooling `crates/client`	MIT License	Maximizes compatibility (including GPL) for integration into any project.
Product / Server Application `crates/server`	FSL-1.1-Apache-2.0	Functional Source License that protects against commercial competitive hosting, converting to Apache-2.0 two years after release.

description All license texts are available in the repository under the licenses/ directory.

Competitive Hosting

Commercial competitive hosting of the server components (offering CameoDB as a managed service) is restricted by the Functional Source License.

After exactly two years from the release date, the FSL future grant automatically converts the code to the permissive Apache-2.0 license.

SDKs & Integration

SDKs and clients remain MIT-licensed for maximum adoption. You can embed our client tooling into closed-source or GPL projects without restriction.
