A battle-tested Next.js starter kit that removes the friction from building subscription software. Everything is wired together and working out of the box — authentication, database, billing, and webhooks included. Just npm install and you’re ready to customize.

Switch from SQLite to Postgres with two lines of config when you’re ready for production. The entire payment flow is tested end-to-end, including Stripe Checkout, the customer billing portal, and webhook synchronization.

What you get:

• Next.js 14 project with email/password authentication via NextAuth
• Prisma ORM with SQLite (swappable to Postgres)
• Stripe Checkout integration for subscriptions
• Customer billing portal for managing payments
• Webhook handlers for real-time payment syncing
• Protected dashboard and authenticated routes
• Tailwind CSS for styling
• Full end-to-end tested payment flow
• Unlimited project usage rights
