How to choose
Start with the job you need done: adding login to an app you are writing, or putting single sign-on in front of services you already run. The first is covered by an auth library such as better-auth/better-auth or a backend platform with auth built in like supabase/supabase, while the second calls for a standalone identity server such as goauthentik/authentik or keycloak/keycloak. After that, decide whether you want to self-host and how much setup you will accept, since a library lives inside your code and an identity server is another service to run.
- better-authBest for TypeScript developers who want login built into their own code, with plugins for things like 2FA and multi-tenancy.
- authentikBest for teams that want to self-host an identity provider for SSO across several services, with SAML, OAuth2/OIDC, LDAP and RADIUS support.
- autheliaBest for people already running a reverse proxy who want two-factor login and single sign-on for web apps through a single portal.
