next-auth vs Postman

Next‑auth is an open‑source authentication library built specifically for Next.js, providing a simple way to add sign‑in, sign‑up, and session handling to web applications. It supports a wide range of providers, including OAuth, email, and credentials, and works seamlessly with both server‑rendered and static pages. The library includes built‑in support for JSON Web Tokens, secure cookies, and database adapters, making it easy to integrate with any backend or serverless environment while keeping user data safe.

Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration.
