NextSpark is a complete, production-ready SaaS framework built on Next.js 15. It provides everything you need to launch a SaaS product: authentication, payments, teams, permissions, entities, themes, and more—all pre-configured and ready to customize.
- Authentication — Email/password, Google OAuth, magic links with Better Auth
- Payments — Stripe integration with subscriptions, usage billing, and customer portal
- Teams — Multi-tenant team management with roles and invitations
- Permissions — Granular role-based access control system
- Entities — Dynamic CRUD with automatic API generation and validation
- MCP Server — Every API-exposed entity gets LLM tool-calling (Claude, etc.) for free via the Model Context Protocol
- Themes — Multiple theme support with easy customization
- Plugins — Extensible plugin architecture for adding features
- i18n — Full internationalization with next-intl
- UI Components — 50+ components based on shadcn/ui
- Database — PostgreSQL with migrations and type-safe queries
- Testing — Jest + Cypress setup included
- TypeScript — Full type safety across the entire stack
