Descope vs Auth.js: Features, Pricing and User Reviews 2026

Descope is a platform that handles all authentication and user management tasks for your application. You can build complete login systems using visual workflows, or integrate directly through code using their SDKs and APIs.

It supports many authentication methods: passwordless login through magic links, social logins like Google and Microsoft, multi-factor authentication, single sign-on for businesses, and traditional passwords. The platform also includes security features like bot protection and fraud prevention.

Descope works as a complete identity solution. It manages user sessions, handles permissions and roles, supports multiple tenants for business applications, and connects with other services through webhooks and APIs. There is a free version for small projects and paid plans with more features for growing companies.

Auth.js is a complete authentication solution that works across different JavaScript frameworks. It provides everything needed to add secure login systems to websites and applications. You can let users sign in through their existing accounts on services like Google or GitHub, or you can use email-based magic links, or even traditional username and password combinations.

The library is runtime agnostic, meaning it adapts to work with Next.js, SvelteKit, Express, Qwik, and other frameworks. It handles session management, protects routes, and connects to databases when needed. Auth.js follows web standards and security best practices, making it both safe and reliable. Since it is open source, the code is publicly available for review and contributions from developers worldwide.
