  • Pro (Commercial, Closed Source) Adds advanced tools, integrations, and support. Distributed as binaries/private NuGet under a commercial EULA.

Trademarks (name & logos) are not licensed by AGPL. White-label/OEM requires Enterprise.

Commercial licensing — when to choose Enterprise

Choose Enterprise if you need team software (identity, roles, audit, policies, private updates) or want custom features/contract work (bespoke integrations, connectors, hosting, SLAs).
