About the Project
Better Auth is framework-agnostic authentication (and authorization) library for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code and very short amount time. Whether you need 2FA, multi-tenant support, or other complex features. It lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Currently, the open-source libraries in the ecosystem often require a lot of additional code if you want anything beyond a basic login. Instead of just suggesting 3rd party services when that happens (which can be still be the right choice at times), I think we can do better as a community—hence, Better Auth.
Goals
- Be Comprehensive: Save users from reinventing the wheel for anything related auth.
- Prioritize Best Practices: provide best practices rather than overwhelming configuration options.
- Framework Agnostic: Support most frameworks and avoid framework specific features and solutions if possible.
- Consistency: Provide a consistent and predictable API across all platforms
- Type Safety: Value type-safety and embrace typescript magic when necessary.
Non-Goals
- JWT-Based Authentication: We won’t support JWT-based auth unless provided by a third-party plugin.
- Extensive Customization: Our focus is on giving you opinionated, best-practice defaults, rather than enabling deep customization.
- Supporting Every Non-Node Runtime: While we aim to support all JavaScript runtimes when possible, we won't sacrifice features and functionality just to accommodate non-Node runtimes.
