BuilderKit – Next.js AI SaaS Boilerplate

BuilderKit is a production-ready Next.js boilerplate for launching AI SaaS products quickly. Instead of spending weeks setting up infrastructure, you start with an app foundation that already includes the core modules most AI products need.

What you get

BuilderKit includes a modular architecture and clean TypeScript code, making it easier to add your own features without rebuilding the basics.

• 17 preconfigured AI applications to use as starting points
• Modular structure designed for extending and customizing
• TypeScript-first codebase
• Supabase support for database and authentication

Payments and SaaS essentials

BuilderKit comes with Stripe integration for subscriptions and payments, plus common “enterprise” building blocks for commercial products.

• Stripe billing for subscriptions and payments
• User roles and access management
• Billing and account management features

Who it’s for

BuilderKit is aimed at developers and startup founders who want to ship an AI product faster while keeping control over code quality and architecture. It’s a practical choice if you want to save 40+ hours of development time and focus on product logic rather than routine setup.
