Massvai

Massvai is an AI app builder. Describe the product you want in a prompt and an AI coding agent builds a full-stack Next.js 15 + TypeScript + Tailwind application you can preview live and export. **What you get** - **AI coding agent** — turns a plain-language description into working application code. - **Live preview** — see the app running while it is being built. - **Supabase** — authentication and database wired in automatically. - **Stripe** — payments ready to configure. - **GitHub sync** — keep the generated repository under your own account. - **One-click Vercel deploy** — ship to production without leaving the builder. You own the code and can export the whole codebase at any time — no lock-in. **Who it's for** Indie founders and developers who want a real, exportable Next.js and Supabase codebase for SaaS products, internal tools and web apps, without starting from an empty repository. **How it works** Write a prompt describing the product, let the agent scaffold and implement it, refine in the live preview, then export the code or deploy with one click. Free to start.
