NEXTDEVKIT is a full-stack OpenNext and Next.js SaaS starter kit that bundles authentication, payments, database, file storage, and multi-platform deployment into one template, letting developers launch production-ready SaaS applications in days instead of months.
What is NEXTDEVKIT?
NEXTDEVKIT is a comprehensive SaaS starter kit built on Next.js 15, OpenNext, and SST. It takes a developer's project idea as input and produces a fully functional, deployable application with pre-built features like authentication (BetterAuth with OAuth), payments (Stripe, Creem), database (Drizzle ORM with PostgreSQL, Cloudflare D1, AWS RDS), file storage (S3, R2), UI components (shadcn/ui, TailwindCSS), and more. The kit is created by a team of experienced developers and is designed to work out-of-the-box on Vercel, Cloudflare Workers, and AWS.
