Authentik questions

Is Authentik open source?

Yes — it is released under MIT (+EE).

Can Authentik replace Okta?

Our verdict on Okta is YES. Vaultwarden (45k stars), Keycloak (28k stars), Authelia (24k stars) are mature open-source replacements for Okta — self-host in one command and stop paying $17/mo.

Can I self-host Authentik?

Yes — we rate it medium to self-host, and it runs on your server.
