Better Auth
Auth that lives inside your app, composable, plugin-based, built to scale.

Better Auth is a framework-agnostic authentication and authorization framework for TypeScript that runs inside your own codebase. It ships with a comprehensive set of built-in features including 2FA, passkeys, multi-tenancy, SSO, and more, all extendable via a plugin system. An optional hosted infrastructure layer adds a dashboard, audit logs, and real-time security threat detection.
Developers install Better Auth into their TypeScript project and compose authentication features through a plugin-based API, optionally connecting to hosted infrastructure for dashboards and security detection.
