Describe the product and Zone51 builds the SaaS: customers sign up as their own company workspace, invite their team with roles, and only ever see their own data. Connect your own Stripe account when you're ready to charge.

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 the product
Who your customers are, what their teams do in it, and what they'd pay for. Plain English is fine.
02
It builds the SaaS
Workspaces, roles, sign-in, the database and every screen are built and checked, with a live preview you can sign in to.
03
Launch and own it
Publish on your own link in one click, add your own domain, and export the whole codebase 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 SaaS builder
The AI SaaS builder for software you can sell.
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.

More you can build
Everything a SaaS needs before its first customer.
The parts that turn an app into a product other companies pay for. Zone51 builds them in from the first version, so you aren't bolting them on later.
Workspaces
Every company in its own space
Customers sign up as a company and invite their people. Each record belongs to one company, and the server checks that inside the database query itself, so one customer can never list or open another's data.
Roles
Owners, admins and members
Roles are checked on the server on every change, new people get the least power by default, only owners and admins change who's in, and the last owner can never be removed.
Payments
Checkout through your own Stripe
Add your Stripe keys in the Backend panel and the app can send customers to Stripe Checkout and confirm payments with signed webhooks. The keys stay on the server.
Tested
Attacked on purpose
In Zone51's own security testing, a multi-company project manager it built was hit with 16 attempts to reach another company's records. It refused every one.
Included automatically
The multi-company plumbing, done properly.
▦
Company workspaces
Every record belongs to one customer company, and lists and searches only ever return that company's rows.
⚿
Roles and invites
Owner, admin and member roles, checked on the server on every change.
⛁
Sign-in and a database
Email and password accounts and a Postgres database, designed from your description.
◇
Payments with your keys
Stripe Checkout and signed webhooks, using keys you add in the Backend panel.
✓
Checks before going live
A security scan runs before every publish and stops it if it finds a critical problem.
↗
It's your code
Export the whole codebase whenever you like and run it anywhere. Exporting isn't a paid extra.
FAQ
Questions, answered.
What is an AI SaaS builder?
+
A tool that builds software-as-a-service from a description: one app that many customer companies sign up for, each with its own private data. Zone51 builds the screens, the database, the sign-in and the rules that keep customers apart.
How does it keep each customer's data separate?
+
Every record belongs to a person or a company, and the server checks that on every read and write, inside the database query itself. Someone from another company asking for a record gets the same answer as if it didn't exist.
Can my SaaS take payments?
+
Yes, through your own Stripe account. Add your Stripe keys in the Backend panel and ask for checkout. The keys are stored encrypted, stay on the server and are never sent to the AI model.
Is the AI SaaS builder free to try?
+
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. A SaaS with workspaces and roles is a bigger build than a one-page site, so it uses more of them.
Can I put my SaaS on my own domain?
+
Yes. Every app goes live on its own zone51.app link, and you can add your own domain once you prove you own it with a DNS record. You can also export the code and host it anywhere.
