AI app builder that ships full-stack Next.js, Supabase and Vercel apps.
Massvai is an AI app builder that turns a plain‑language product brief into a production‑ready full‑stack Next.js application. The platform plans the work, writes clean TypeScript with a maintainable component architecture, and provides a live preview while the durable AI coding agent handles edge cases and progress across long‑running tasks. Users describe their app, optionally add screenshots or reference files, and Massvai generates a scaffolded Next.js 15 project with Tailwind design system, Supabase authentication, and accessible UI. Every file can be inspected, exported, and synced to GitHub, then deployed to Vercel with a one‑click guided flow. The free forever plan includes 100 welcome credits and requires no credit card; paid plans add monthly or annual credits. Massvai targets founders, product teams, agencies, developers and solo builders who need more than a prototype, offering tools for SaaS products, internal tools, and client websites, all without platform lock‑in.
