Give your TypeScript app a deliberate authentication foundation.

About Better Auth
Better Auth provides authentication components that run within a TypeScript application. It supports common account flows and a plugin-based approach to capabilities such as organizations, access control, and additional sign-in methods. The framework is free and open source; optional managed infrastructure has separate plans, quotas, and usage charges. Use it when you want to understand how identity fits into your own application stack. For a first release, implement only the account flows you need, then test session expiration, password recovery, verification, and authorization on protected records. Adding a login screen alone does not establish correct data access. Better Auth participated in YC Spring 2025.
