It is a CNCF incubating project under Apache 2.0. - **Pick Authentik** if you want a modern admin UI, customizable login flows, and a built-in forward-auth proxy for apps that cannot speak OIDC or SAML, and you do not mind a single-company roadmap and an MIT core with paid enterprise features. - Both are free to self-host, both speak **OIDC, OAuth 2.0, and SAML 2.0**, and both run fine in production. The decision is maturity and protocol depth versus developer experience and lighter setup. Authentik and Keycloak are the two leading open-source, self-hosted identity providers. **Keycloak** is older, CNCF-backed, built on Java/Quarkus, and the safer choice for large or SAML-heavy deployments. **Authentik** is newer, built on Python and Go, with a friendlier admin UI, flexible authentication flows, and a built-in application proxy. Choose Keycloak for maturity; choose Authentik for developer experience. ## What is Keycloak? Keycloak is an open-source [identity and access management server](https://www.keycloak.org/?ref=edgewisely.com) that handles single sign-on, identity brokering, social login, and user federation against LDAP and Active Directory, all from an admin console. It supports **OpenID Connect, OAuth 2.0, and SAML 2.0**. Originally built at Red Hat, Keycloak is now a [Cloud Native Computing Foundation incubating project](https://www.cncf.io/projects/keycloak/?ref=edgewisely.com), accepted on **April 10, 2023**, and licensed under **Apache 2.0**. It runs on **Java and Quarkus**, having migrated off the older WildFly/JBoss application server. The [latest stable release is 26.7.1](https://github.com/keycloak/keycloak/releases?ref=edgewisely.com) (August 2026). For teams that want vendor support, Red Hat ships a commercial build of Keycloak under subscription. ## What is Authentik? Authentik is an open-source identity provider built and maintained by **Authentik Security, Inc.**, a public benefit company. Its core is [MIT-licensed](https://github.com/goauthentik/authentik/discussions/18682?ref=edgewisely.com), with an enterprise directory governed by a separate commercial license tied to a paid subscription. Its stack is **Python/Django** at the core, **Go** for its outposts and reverse proxy, plus a TypeScript frontend. The [latest release is 2026.8](https://goauthentik.io/blog?ref=edgewisely.com) (September 1, 2026), on a roughly quarterly cadence. Authentik's signature features are **flows and stages** (a customizable authentication pipeline), **blueprints** for config-as-code, and **outposts** — including a proxy provider that does forward-auth for apps that cannot speak a standard protocol. ## Authentik vs Keycloak: the differences that matter The split comes down to maturity versus developer experience. Keycloak is older, broadly deployed, vendor-neutral under the CNCF, and has the larger ecosystem of integrations and adapters. Authentik is newer, has a more modern admin UI and more flexible login flows, but a company-controlled roadmap. | | **Authentik** | **Keycloak** | | --------------------- | ----------------------------------------------------------------- | ---------------------------------------------- | | **Backed by** | Authentik Security, Inc. (public benefit company) | CNCF incubating project; originated at Red Hat | | **License (core)** | MIT core; enterprise dir under commercial license | Apache 2.0 | | **Latest release** | 2026.8 (Sep 1, 2026) | 26.7.1 (Aug 2026) | | **Stack** | Python/Django, Go, TypeScript | Java / Quarkus | | **Protocols** | OIDC, OAuth 2.0, SAML 2.0, SCIM, LDAP, RADIUS, forward-auth proxy | OIDC, OAuth 2.0, SAML 2.0 | | **User federation** | Yes (LDAP sources) | Mature LDAP / AD / Kerberos | | **Commercial option** | Authentik Enterprise subscription | Red Hat build of Keycloak | | **Maturity** | Newer, smaller ecosystem | Older, enterprise-proven, larger community | ## Which is easier to self-host? Authentik is generally the lighter lift to stand up and administer. Its Docker Compose setup and admin UI are approachable, and its flows let you model custom login logic without writing Java. Keycloak's Quarkus distribution is a solid, well-documented container, but its Java footprint is heavier and its realm and client model has a steeper learning curve. Both run on Kubernetes and both need an external database (typically PostgreSQL) in production. If your bottleneck is "get SSO running this afternoon," **Authentik** usually wins. If you already have Java operational experience, Keycloak's maturity offsets the heavier runtime. ## Which has better protocol and feature coverage? Authentik covers more protocols out of the box. It ships [providers for OAuth2/OIDC, SAML 2.0, SCIM, LDAP, RADIUS, and a forward-auth proxy](https://docs.goauthentik.io/docs/add-secure-apps/providers/?ref=edgewisely.com), plus remote access (RDP/SSH/VNC) and directory provisioning. Keycloak focuses on the big three — **OIDC, OAuth 2.0, and SAML 2.0** — but goes deeper on each, with especially mature **SAML** and user federation against LDAP, Active Directory, and Kerberos. The practical tell: to protect a legacy app that speaks no modern protocol, Authentik's built-in proxy is the cleaner answer. For battle-tested SAML and enterprise directory federation, Keycloak has the longer track record. ## Is Authentik or Keycloak better for production? Both are production-ready. For large-scale or compliance-sensitive deployments, **Keycloak** is the lower-risk pick: it is older, more widely deployed, vendor-neutral under the CNCF, and backable by a Red Hat subscription. **Authentik** is production-ready too — it ships stable quarterly releases and runs in real deployments — but you are betting on a single company's roadmap, and some capabilities sit behind the enterprise license. Paid support subscriptions start around $1,000 per year. ## Who should use which? Match the tool to your scale, your protocol needs, and your appetite for operating Java. - **Solo self-hoster or homelab:** **Authentik.** Faster setup, nicer UI, and the built-in proxy secures apps that do not do OIDC or SAML. Everything you need is in the MIT core. - **Startup or small platform team:** Either. Pick **Authentik** for speed and modern UX; pick **Keycloak** if you expect SAML-heavy enterprise customers or want a vendor-neutral foundation. - **Enterprise platform team:** **Keycloak**, with the option of a Red Hat subscription for support and a hardened build. Its maturity, ecosystem, and deep federation fit regulated, large-user-base environments.

Both are self-hosted open-source SSO servers. Keycloak is a Java/Quarkus CNCF project under Apache 2.0, older and strong on SAML and directory federation. Authentik is a Python/Go project with an MIT core, a modern admin UI, customizable flows, and a built-in forward-auth proxy. Keycloak favors maturity; Authentik favors developer experience. ### Is Authentik better than Keycloak? Neither is universally better. Authentik is better for fast setup, modern UX, and protecting apps that lack OIDC or SAML support through its proxy. Keycloak is better for mature SAML, enterprise directory federation, vendor-neutral governance, and large-scale deployments with commercial support. Your stack and scale decide, not raw feature counts. ### Can Authentik replace Keycloak? For most SSO and OIDC/SAML use cases, yes. Authentik speaks the same core protocols plus SCIM, LDAP, and RADIUS, so it can cover what many Keycloak deployments do. The gaps are Keycloak's deeper SAML maturity, larger integration ecosystem, and CNCF vendor-neutral governance, which matter most at enterprise scale. ### Is Authentik production ready? Yes. Authentik ships stable releases on a roughly quarterly cadence — the latest is 2026.8 (September 1, 2026) — and runs in real production environments. The caveats are a smaller ecosystem than Keycloak, a single-vendor roadmap, and some features gated behind the paid enterprise subscription. ### Is Keycloak still maintained? Yes, actively. Keycloak is a CNCF incubating project with frequent releases; the latest stable version is 26.7.1\. Red Hat also ships a supported commercial distribution, the Red Hat build of Keycloak. It remains one of the most widely deployed open-source identity providers. --- **Editor's note — sources:** Keycloak project site (keycloak.org); CNCF Keycloak project page (cncf.io); Keycloak releases (github.com/keycloak/keycloak); Authentik licensing discussion and enterprise terms (github.com/goauthentik/authentik); Authentik release notes and support pricing (goauthentik.io/blog); Authentik providers documentation (docs.goauthentik.io).
