> When you self-host Zulip, you get the same software as our Zulip Cloud customers.

> Unlike the competition, you don't pay for SAML authentication, LDAP sync, or advanced roles and permissions. There is no “open core” catch — just freely available world-class software.

The optional pricing plans for self-hosted mention that you are buying email and chat support for SAML and other features, but I don't see where they're charging for access to SAML on self-hosted Zulip.
