FusionAuth
Customer identity and access management server, self-hosted or hosted by FusionAuth, with a free Community edition.
fusionauth.iorepositorydocspricing
FusionAuth is a customer identity and access management server. Applications send users through its OAuth 2.0 and OpenID Connect endpoints, and the admin UI and the REST API manage the instance. It also accepts logins from external SAML v2 identity providers and can authenticate against an LDAP directory. The server bundles its own Java runtime and needs PostgreSQL or MySQL, plus an OpenSearch or Elasticsearch search service. It installs from Docker Compose, from packages on Linux, macOS and Windows, or on Kubernetes. Advanced themes, which customize the HTML, CSS and messages, are written as Freemarker templates. FusionAuth Cloud runs an instance for those who choose a hosted service.
Worth knowing
The server is distributed under the FusionAuth Customer License Agreement. The Community edition is free, and advanced features are enabled through plans that use a license key entered on the instance. The GitHub repository holds container definitions, not the server’s source.
