What's Good

Apache-2.0 outside ee/. Frontend SDK + backend SDK + Java core. Passwordless, social, MFA, multi-tenancy. Pricing page: self-hosting the open-source features is free without any limits.

The Catch

Three processes, not a single library. ee/ is not Apache. Cloud is MAU-metered; MFA and account-linking have 100 USD/month minima on Cloud. Read the carve-out before you assume the whole repo is Apache-2.0.

Verdict

Apache-2.0 auth with no self-host MAU cap. Architecture is three pieces.
