Type one sentence and Zone51 makes a browser game: 2D or 3D, keyboard, gamepad and touch controls, sound, a title screen and a saved best score. Before you see it, Zone51 plays the game itself to catch anything broken.
2D and 3D gamesPlays on phones tooYour code to export
Zone51 is an AI app builder: you describe the software you want in plain English, and it builds a real web app that you can use, publish and keep.
01
Describe it
The kind of game, how you win or lose, and anything that makes it yours. One sentence is enough to start.
02
Watch it build
Zone51 picks the right engine for the genre, builds the game, then plays it in a browser to check it works.
03
Play, share, own it
Publish it on its own link in one click and send it to anyone. Export the code whenever you want.
What you get automatically
Sign-inEmail and password accounts, passwords stored as one-way hashes.
DatabasePostgres with real tables, designed from what you describe.
SecurityProtections that fit your data, and a scan before every publish.
HostingOne click puts it live on its own link. Your own domain works too.
Code exportThe whole codebase as a .tar.gz, ready to run anywhere.
Full apps get all five. A website or game that needs no accounts skips sign-in and the database.
AI game builder
The AI game builder for games you can play.
Built by Zone51 and running right now: real apps it made from a description and published. What you see is footage of the live app, not a mockup. Open any of them and try it.
A team workspace where each company is kept separate, with members, roles, usage and billing screens.

FAQ
Questions, answered.
Can I make a game with AI for free?
+
New accounts get free starter credits once: 300,000 AI credits and an hour of preview time, and sign-up doesn't ask for a card. Credits follow how much AI work a change takes, so a bigger game uses more of them than a small one.
Can it make 3D games?
+
Yes. 3D games use three.js with Rapier physics, for things like driving, flying and 3D runners. 2D action games use Phaser 4, and card, board and idle games run in the page without an engine.
Do the games work on phones?
+
Yes. Every game gets on-screen touch controls on phones, a fullscreen button, and keyboard and gamepad support on a computer.
Can it make Roblox or Unreal games?
+
No. Zone51 makes games that run in a web browser, so anyone can play them from a link without installing anything.
Who owns the game?
+
You do. You can export the whole codebase, and the bundled game art is CC0, which means it's free to use, including commercially.
