Replace Auth0 with self-hosted identity management. Compare Logto and Keycloak — no MAU pricing, unlimited users.
Auth0 charges $35-$240/month based on monthly active users. Keycloak is battle-tested at enterprises worldwide and handles SSO, LDAP, MFA, and social login for free. Logto is a more modern alternative with a better developer experience.
Keycloak for enterprise use with LDAP/AD integration and complex identity brokering. Logto for modern apps with a better developer experience and lighter resource footprint.
