What's Good

Apache-2.0. Self-host Kratos (identity), Hydra (OAuth2/OIDC), Keto (Zanzibar authz), Oathkeeper (IAP). Pick the pieces you need. Same APIs as OEL/Network.

The Catch

Vs Keycloak: modular Go you compose, not one Java IAM. Ory own compare table still labels Ory Open Source Evaluation and prototyping; FAQ steers prototypes to OSS and scale to OEL/Network. Ory Cloud/Network is not the free path. Not a Dex/Keycloak/Casdoor twin.

Verdict

Apache-2.0 modular Go IAM. Compose pieces; their table still says prototyping.
