-  Auth.js is now part of [Better Auth](https://better-auth.com). We strongly
-  recommend new projects to start with Better Auth unless there are some

 # What is Auth.js?
 
 Auth.js is a <abbr title="Designed to work seamlessly across different JavaScript runtime environments without relying on specific features or behaviors of any particular runtime">runtime agnostic</abbr> library based on standard Web APIs that integrates deeply with multiple modern JavaScript frameworks to provide an authentication experience that's simple to get started with, easy to extend, and always private and secure!
