Auth

Auth.js is an open source authentication library for modern web applications that provides full control over your data and identity flow.

Auth.js (formerly NextAuth.js) is the standard for implementing secure, flexible authentication in the JavaScript ecosystem. It supports over 75 popular OAuth providers—including Google, GitHub, and Apple—while offering built-in protection against CSRF and session hijacking. By utilizing standard Web APIs, the library runs on any platform (Node.js, Serverless, or Edge) and integrates with major databases like PostgreSQL and MongoDB through dedicated adapters. It is designed for developers who need to own their authentication layer without the overhead of third-party SaaS costs or vendor lock-in.
