Authentik has emerged as the leading modern alternative to Keycloak for organizations that want self-hosted identity management without the operational complexity of enterprise Java applications. Built in Python with a React frontend, Authentik provides a cleaner developer experience while supporting the same breadth of authentication protocols including SAML 2.0, OAuth2, OpenID Connect, LDAP, RADIUS, and SCIM for user provisioning. The customizable flow system allows administrators to define exact authentication journeys including login, registration, recovery, and multi-factor verification steps.
The platform excels at centralizing identity across diverse application landscapes. Modern web applications connect through OAuth2 or OIDC, legacy enterprise systems integrate via LDAP, and applications without native SSO support gain authentication through Authentik's proxy provider that intercepts requests at the reverse proxy layer. This protocol versatility means organizations can unify authentication across their entire stack without requiring every application to support the same identity standard.
Authentik Security, the public benefit company behind the project, offers paid Enterprise and Enterprise Plus plans; the current pricing page lists Enterprise at $5/user/month plus $0.02/external user/month pricing, while the repository license keeps most non-enterprise code MIT and separates enterprise-directory terms. The project has grown to 22K+ GitHub stars, with docs currently tracking the 2026.5 release line and a community contributing integrations, themes, and deployment guides. Deployment options span Docker Compose for small setups through Kubernetes Helm charts for production clusters, with Terraform support and AWS CloudFormation templates for infrastructure-as-code workflows.
