Introduction

Better Auth RS brings Better Auth’s authentication model to Rust: an auth instance, your database, and plugins for the features you need. Use SQLx or SeaORM for storage and Axum for routing and session extraction.

Source-only project

Use this project directly from Git. APIs, wire formats, and schemas may change.

Get started

1. Build an auth instance and start a server.
2. Sign up, sign in, and read a session.
3. Add plugins for passwordless login, two-factor authentication, organizations, and more.

These docs follow Better Auth’s topics and cover the Rust backend. The tested HTTP compatibility target is better-auth@1.7.6; see compatibility for the supported contract.
