Massvai

Massvai turns a product idea into a working full-stack web app. An AI agent scaffolds a Next.js project with a Tailwind design system, wires Supabase authentication and database, and builds the UI while you watch a live preview. You own the code: export it, sync it to GitHub and deploy to Vercel through a guided flow. Built for solo founders and small teams shipping MVPs, internal tools and SaaS products. Free-forever plan, no credit card.
