Describe the software.
Own the software.
Zone51 is an AI app builder for real software: online stores, booking systems, finance apps, AI tools, with real sign-in and a real database. Say it in plain English and watch it come alive, piece by piece.
Describe it once,
watch it get built.
Every screen here is a real app Zone51 built from a description and published. Open any of them and try it.
What Zone51 is,
and what it does.
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.
Describe it
Say what you want, the way you'd explain it to a friend. Add a screenshot if you like.
It builds a real app
Zone51 writes the code, sets up the database and sign-in, and checks each layer right in front of you.
Publish & own the code
Go live on your own link in one click. Export the whole codebase whenever you want. It's yours.
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.
Every full app ships with
the hard parts done.
A real database
Postgres, with tables, relations and your data, set up for you.
Sign-in & accounts
Sign up, log in and private data per user, from the very first build.
Looks great everywhere
Polished, responsive screens on desktop, tablet and phone.
Live preview
Watch your app take shape and click through it while it builds.
Undo anything
Every change is a save point. Jump back to any version, instantly.
It's your code
A real Next.js codebase in git. Export it and run it anywhere, forever.
Apps, SaaS, websites
and games.

answered.
Can I build an app with AI without coding?
+
Yes. Describe the app in plain English, the way you'd explain it to a friend, and Zone51 writes the code, sets up the database and sign-in, checks the result, and shows it to you in a live preview. You change it the same way: by saying what you want.
Do I own the code?
+
Yes. Every app is a real Next.js and TypeScript codebase. Export code downloads all of it, including the database migrations, so you can run it anywhere or hand it to a developer. Exporting isn't a paid extra.
What's in a full-stack app →How much does it cost?
+
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. After that, credits are used according to how much AI work each change takes, not per click or per build. When you need more, there are monthly plans and one-off credit packs that never expire, on the Billing page. If a build fails because of our system, its credits are refunded automatically, up to a daily limit.
Is my app secure?
+
Zone51 works out what kind of information your app handles and adds the protections that fit: passwords stored properly, each person's data checked on the server, keys kept off the page, and security headers. It scans the app again before you publish and stops the publish if it finds a critical problem. No tool can make software perfectly secure, so have apps that handle health or financial data reviewed before real people use them.
What Zone51 protects automatically →Can it build games?
+
Yes. Ask for a game and Zone51 builds a browser game in 2D or 3D, with a title screen, pause, saved best score, sound and touch controls on phones. It plays the game itself before handing it over.
More about the AI game builder →Can I build a website instead of an app?
+
Yes. Choose Frontend only for landing pages, portfolios and product sites that don't need a database. Choose Full app when people should sign up, log in or save things.
More about the AI website builder →Does it make iPhone or Android apps?
+
Zone51 builds web apps. They run in any browser and are built to work at phone size, but they aren't App Store or Google Play apps.
