Authentik: Open-Source Auth Without the SaaS Lock-In
Self-hosted authentication that handles OAuth, OIDC, and user management—no vendor dependency, no per-user fees.
goauthentik/authentik ↗Authentication is the boring infrastructure every app needs: sign-up forms, password resets, social login buttons, permission checks. Most builders reach for Auth0 or Okta and pay monthly fees per user. Authentik is the open-source alternative you can run on your own servers. It handles the entire auth stack—OAuth2, OIDC, LDAP, SAML—plus user directories, MFA, and conditional access policies. You get the flexibility to customize without begging a vendor. The trade: you manage the infrastructure yourself. If you're shipping a product with real users and auth is becoming a line item, this cuts weeks of custom integration work and keeps your user data under your roof.

Authentik: Auth0-grade auth without the bill
Self-hosted authentication that eliminates weeks of OAuth/OIDC plumbing. Handles user directories, MFA, conditional access—all open-source, all yours to control. Useful if you're shipping product and tired of vendor lock-in.
Most builders outsource auth to Auth0 or Okta. Authentik is the open-source answer: OAuth2, OIDC, SAML, user directories, MFA—all self-hosted, zero per-user fees. You manage the infra, you own the data. If auth is becoming a budget line, it's worth the setup. https://github.com/goauthentik/authentik
Authentication infrastructure doesn't have to be a recurring cost. Authentik gives you production-grade auth—OAuth2, OIDC, SAML, user management, MFA—with the control of open source. Self-hosted, no per-user pricing, full customization. For product teams shipping at scale.
Just shipped a feature that required OAuth, SAML, and OIDC flows. Spent three days on boilerplate before I realized I was reinventing what authentik already does. Authentik is the auth glue OSS projects and startups actually need—not a SaaS lock-in, not a toy. It handles user management, SSO, and passwordless flows out of the box. I spun up a self-hosted instance, wired it to my app, and cut two weeks of integration work. Three things that landed for me: → OAuth/OIDC/SAML in one place—no more integration hell → Self-hosted so you own the keys and compliance → Fine-grained access control without the Auth0 bill If you're building anything with users, this saves you from the auth tax.
