Massvai

Massvai is an AI agent that builds full-stack Next.js apps from a prompt, with live preview, Supabase setup, GitHub sync and one-click Vercel deploy. Describe the product in plain language and the agent scaffolds the frontend, API routes and database, then keeps everything in sync as you iterate. The built-in live preview shows every change instantly, Supabase provisions authentication and storage without manual setup, GitHub sync keeps the code in your own repository, and one-click Vercel deploy pushes the finished app to production with a public URL. It is a freemium tool: new users can build and preview apps for free, and paid plans unlock more projects, faster runs and team features. Massvai is aimed at developers, founders and product teams who want to go from idea to a deployed full-stack app in minutes instead of days.
