The Next.js SaaS
starter kit. From idea to launch in hours.
A production-ready Next.js SaaS boilerplate with authentication, Stripe payments, database, and a full admin dashboard — .cursorrules and Cursor skill files built in.
Everything you need to launch a SaaS. Purpose-built for modern teams with AI workflows at its core.
Production-ready
Auth, payments, database, and email — all wired up and tested. Clone and deploy.
AI-native
Structured for Cursor and Claude with .cursorrules, AGENTS.md, and skill files built in.
Fully customizable
A token-driven design system. Change your brand in the visual studio — not in code.
Auth that works out of the box
Email/password, social logins, magic links, and session management. Better Auth handles the complexity so you ship secure auth on day one.
- Email & password with verification
- Google, GitHub, and social OAuth
- Session management & refresh tokens
- Role-based access control
- Protected API routes & middleware
Stripe subscriptions, ready to bill
Plans, pricing tables, checkout sessions, webhook handlers, and a customer portal. Go from zero to revenue in a single deploy.
- Subscription plans with usage metering
- Stripe Checkout & Customer Portal
- Webhook handlers for lifecycle events
- Invoice generation & payment history
- Free trials & promotional coupons
A full admin dashboard included
Customers, products, invoices, and analytics — built with real components from the shared UI library, not placeholder mockups.
- Revenue & growth analytics with Recharts
- Customer & subscription management
- Composable sidebar, tables, and charts
- Command palette with keyboard shortcuts
- Responsive layout with dark mode
A design system, not a template
Every color, radius, font, spacing, and motion value is a design token. Edit them visually in the Studio or let AI suggest changes.
- 60+ design tokens controlling the full UI
- Visual token editor (Studio) with live preview
- AI-powered style suggestions & transfers
- Light & dark themes from a single source
- CSS variable bridge — zero JS runtime cost
Built for the way you work with AI
Structured directories, typed schemas, and documentation that AI agents actually understand. Your Cursor copilot becomes a real contributor.
- .cursorrules with project conventions
- AGENTS.md per package for agent context
- Cursor skill files for kit workflows
- Type-safe Drizzle ORM schemas
- Clean separation of concerns across packages
