Keycloak is an open-source software product to allow single sign-on with identity and access management aimed at modern applications and services.

In April 2023, Keycloak was donated to the CNCF and joined the foundation as an incubating project.

[3] It is possible to integrate Keycloak with other technologies, such as front-end frameworks like React or Angular, as well as containerization solutions like Docker.

[4] The first production release of Keycloak was in September 2014, with development having started about a year earlier.

[6][7] To some extent Keycloak can now also be considered a replacement of the Red Hat JBoss SSO open source product which was previously superseded by PicketLink.
