ferriskey/ferriskey — open-source IAM in Rust with multi-tenant realms and OIDC
trending-repo
HIGH
FerrisKey is an open-source IAM platform built with Rust and hexagonal architecture, offering a cloud-native alternative to Keycloak. It features multi-tenant realms with strong user/role/client isolation, full OpenID Connect and OAuth 2.0 support, and webhooks for event-driven extensibility. Last commit March 27, 2026, 551 stars and growing. Apache 2.0 licensed.

ODS Impact
Directly relevant to OID (the ODS identity service, currently being built from scratch). FerrisKey's hexagonal architecture and multi-tenant realm model closely mirrors the OID spec requirements. Worth monitoring as an architectural reference or potential upstream component. The webhook event model (user/client/realm lifecycle events) maps well to ODS Redpanda CloudEvents pattern. Not a replacement for the custom OID service, but a valuable design reference.
