Introduction

Better Auth is framework-agnostic authentication (and authorization) framework for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities. Whether you need 2FA, multi-tenant support, or other auth releated features. It lets you focus on building your actual application instead of reinventing the wheel.

Why Better Auth?

Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often requires a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
