Keycloak

Keycloak is a leading open-source software project focused on identity and access management. It was originally developed as a project within the community to provide a robust, production-ready tool for single sign-on (SSO) and authentication, enabling applications to secure their services with minimal code. The software is built primarily using Java and follows the standards for protocols like OAuth2, OpenID Connect, and SAML.

The development and maintenance of Keycloak are driven by a global community of contributors, though it is heavily sponsored and stewarded by Red Hat. Because it is an open-source project, its 'manufacturing' or development occurs globally across various cloud environments and private servers where developers contribute code. Today, it serves as the upstream project for Red Hat Build of Keycloak, a commercially supported version offered as part of Red Hat's enterprise middleware and cloud portfolios.

Keycloak is currently under the ultimate ownership of IBM, following the acquisition of Red Hat. It remains a critical component of modern cloud-native security architectures, utilized by developers worldwide to manage user federation, social login, and fine-grained authorization across distributed systems and server agents.
