    Massvai

    freemium • Free to start
    Updated Oct 2026

    Massvai is an AI app builder that turns a plain-English prompt into a full-stack Next.js application with a Supabase backend, ready to deploy on Vercel. You edit by chatting, and you keep the code. Pricing is freemium. Worth weighing: as with any AI builder, complex apps still need hands-on refinement after the first generation.
