HagenKit

HagenKit is a comprehensive Next.js starter kit designed to eliminate weeks of repetitive setup work when building modern SaaS applications. It combines essential backend infrastructure with polished frontend components, allowing developers to focus on their unique business logic rather than reinventing authentication flows and payment integrations.

Built with TypeScript and Prisma, the boilerplate provides a robust foundation with type-safe database operations and structured API routes. The integration of Shadcn UI components and Tailwind CSS delivers a professional, customizable interface out of the box, while the included blog and help center modules add content management capabilities that most SaaS products eventually need.

What distinguishes HagenKit is its enterprise-ready architecture that handles production concerns from day one. The authentication system, payment processing setup, and database schema are production-tested patterns that scale with your application. This makes it ideal for solo developers and small teams who want to ship quickly without accumulating technical debt.

With active maintenance and a growing community of contributors, HagenKit serves as both a learning resource for Next.js best practices and a practical launchpad for commercial projects. The open-source nature means you retain full control and can customize every aspect to match your specific requirements.
