Deploy and Host NextJS16 with MongoDB and better-auth on Railway

What is NextJS16 with MongoDB and better-auth? NextJS16 with MongoDB and better-auth is a modern full-stack web application stack combining the React-based Next.js 16 framework, a scalable MongoDB database, and a lightweight authentication system. It enables developers to build secure, server-rendered or edge-ready apps with user accounts, sessions, and persistent data.

About Hosting NextJS16 with MongoDB and better-auth

Hosting NextJS16 with MongoDB and better-auth involves deploying a full-stack JavaScript application where the frontend and backend logic run inside a Next.js server, connected to a MongoDB database for persistent storage and using better-auth for authentication flows such as login, signup, and sessions. On Railway, this stack is simplified through managed services, environment variables, and built-in scaling. Developers configure database connections, authentication secrets, and runtime settings, while Railway provisions the infrastructure, networking, and deployment pipeline automatically, allowing rapid iteration and production-ready hosting with minimal DevOps overhead.

Common Use Cases

SaaS dashboards with user authentication and subscription data stored in MongoDB
Internal tools with secure login and role-based access
Full-stack web apps (blogs, marketplaces, admin panels) using server-side rendering and API routes
