Next.js SaaS Starter

With over 10K stars on GitHub, this Next.js SaaS boilerplate is the most popular one available. It's a complete solution packed with everything you need to launch your SaaS or any web app and start earning online quickly.

It's developed by Vercel, the company behind Next.js, and it's completely open source and free. You can review the actual code to evaluate its quality before investing time in it. The codebase is actively maintained and updated regularly.

It includes support for authentication (email/password authentication using JWTs stored in cookies — it does not use Auth.js), Stripe integration for payments, and a dashboard for authenticated users.

It uses Drizzle as the ORM for managing the database and is compatible with Postgres. You can run database migrations and seed the database with a default user and team.

For the UI, it uses the popular shadcn/ui library — a set of components built on top of Radix UI and Tailwind CSS. It's a great choice for building quickly and is fully customizable.

Features:

• Marketing landing page
• Dashboard pages with CRUD operations for users and teams
• Basic RBAC (Role-Based Access Control) with Owner and Member roles
• Subscription management with Stripe Customer Portal
• Email/password authentication with JWTs stored in cookies
• Global middleware to protect authenticated routes
• Activity logging system for user events

Currently, it does not include email service support, so you'll need to implement this yourself. This is a limitation, especially since there's no built-in password reset flow.

You may want to enhance the authentication system by integrating Auth.js or another provider. Adding social login options like Google authentication would also be beneficial.

Get started quickly with Next.js, Postgres, Stripe, and shadcn/ui. Don't waste time reinventing the boilerplate—focus on what makes your product unique.
