Massvai

Massvai is an AI full-stack Next.js app builder for indie founders and developers. Describe a product in a prompt and an AI coding agent builds a production-ready Next.js 15 TypeScript Tailwind app with live preview, Supabase auth and database, Stripe, GitHub sync, and one-click Vercel deploy. You own and can export the code. Built for real SaaS, internal tools, and web apps that need an exportable codebase rather than a locked sandbox.
