keycloak.org·Analyzed 56 minutes ago·Based on 2 sources

Keycloak - the open source identity and access management solution. Add single-sign-on and authentication to applications and secure services with minimum effort.

Depends

Depends

Keycloak fits organizations with several apps, DevOps capacity, and a need for centralized SSO at zero license cost.

Powerful free SSO/IAM — but you run it. Great for multi-app orgs with ops staff; overkill if you just need login.
