The open-source TypeScript auth framework.
Better Auth is an open-source authentication framework for TypeScript apps. Auth is defined in code through a `betterAuth()` config — email and password settings, social providers, and plugins — so it stays version-controlled, type-safe, and reviewable in pull requests rather than managed through a dashboard. Credential auth with sessions, email verification, and password reset is built in, and a plugin system covers everything from passkeys and two-factor to organizations and enterprise SSO.
