Base44

Base44 turns a plain-English description into a working full-stack web application with frontend, backend, database, user authentication and hosting handled for you, with no configuration. It reached over two million users and was acquired by Wix in June 2025 for around $80 million, roughly six months after launch, so the platform has substantial backing behind it. Two things determine whether it fits. Credits split into two pools: message credits spent while you build, and integration credits consumed at runtime when your app calls a service, and neither rolls over. The free tier is genuinely usable for evaluation but most users exhaust it within hours of serious building, with paid tiers running roughly $20 to $200 monthly. And the trade-off for that convenience is lock-in: the backend is Base44's own, so migrating data out later is genuinely difficult.
