# Better Auth

> Open-source TypeScript authentication framework for modern web applications.

Better Auth is a comprehensive, open-source authentication framework designed for TypeScript web apps. It supports common identity standards like OAuth2 and OIDC alongside modern ecosystem adapters like Drizzle, Kysely, and SvelteKit. Developers turn to it as a flexible, self-hosted alternative to proprietary auth services or complex legacy libraries.
