Overview
Better Auth is an open-source authentication and authorization framework that lives inside your own app and database. It ships email/password, social sign-on, two-factor auth, passkeys, organizations, and SSO out of the box, with a plugin system to extend it — a self-owned alternative to hosted auth services like Clerk and Auth0, with no per-user pricing or vendor lock-in.
