Description
Better Auth is an open-source authentication framework for TypeScript, created by Bereket Engida, that gives developers a complete auth layer they own and run inside their own application. It works across frameworks and databases, covering email and password, social login, and session management out of the box, while a plugin system adds two-factor authentication, organizations, and more advanced flows. Because it runs inside the application, teams keep full control of user data in their own database.
Key Capabilities:
Framework-agnostic core that works with Next.js, SvelteKit, and others
Email, password, and social login with session management built in
A plugin system for two-factor auth, organizations, and passkeys
Database adapters for Postgres, MySQL, SQLite, and ORMs
Type-safe APIs that surface auth state across client and server
Self-hosted operation that keeps user data in the team's own database
