Keymate – Modern Authorization for Developers

Keymate is the missing piece for Keycloak-based access control. Built natively on Keycloak and OpenFGA, it adds fine-grained, risk-adaptive, and data-sensitive authorization — all without replacing your IAM. ✔ Plug into any Keycloak (or other IAM) with zero migration ✔ SDKs for Java, .NET, JS — with @permission annotations ✔ Built-in “Why Denied?” simulations and visual DSL ✔ Support for ReBAC, PBAC, RADAC, DSAC ✔ Organization-aware tokens and multi-tenant delegation ✔ Fully event-driven and OpenTelemetry-native For developers, for teams, for IAM at scale — powered by Keycloak, extended by Keymate.
