Describe the app you want. Base44 builds the frontend, backend, auth, and database together.
Where many "AI app builders" stop at a pretty UI, Base44 wires up the unglamorous half — authentication, a database, storage, and integrations — automatically. You chat the app into existence and it actually runs, with real persistence and users, not a mockup. That makes it the closest thing to "I described a SaaS and it exists" we've tested.
Who it's for: Founders, automators, and ops leads who need a working internal tool or MVP without hiring a backend engineer.
Auth, DB, storage, and secrets provisioned for you. No separate cloud account to wire up.
Refine the app in conversation. Each message edits the live project — no redeploy cycle.
Hook into email, payments, and third-party APIs through built-in integration blocks.
Your app goes live on a Base44 subdomain (or your own) the moment it compiles.
Base44 is the strongest "describe it and it runs" builder we've tried because it owns the backend. For MVPs and internal tools it's a $20/mo no-brainer. When you outgrow it, you'll export the concept — not the code — and rebuild properly. That trade is worth it for speed.
