Local browser
Watch your app get built. Your AI writes it, and a real browser next to it shows every change as it happens. The AI checks its own work there, before you have to.
Build your app on your own computer. Own every part of it.
Cloud builders rent you their AI and keep your app on their servers. GPrint runs on your Mac or Windows PC with the AI you already pay for, and the app it builds is yours: a folder, your data, your own address online. No coding.

What you get
Everything your AI needs to build you a real app.
Local database
See everything your app knows. Customers, orders, bookings, in a plain list on your computer. Sort it, search it, and switch to what real customers are putting in.
Local. Dev. Live.
Put it online with one button. Local is your computer. Dev is a private copy to check. Live is for customers. Nothing goes live half-done.
How it works
Three things to do.
GPrint ticks each one when it can see it is done.
- 1Open a folderNew, or the app you already have. Nothing is installed without asking you.
- 2Talk to your AIPick the one you already use. It runs here, on your own account.
- 3Follow the stepsSay what the app is for, build the first screen, run it, then send it online.
Security
Enterprise-grade security. Everything runs on your computer.
GPrint has no server holding your work. Your app, your data and your AI stay on your computer, and what goes online goes to accounts you own.
Your AI, your sign-in
Your AI runs under your own login and plan. GPrint never sees it and never pays for it.
A normal folder
Your app lives on your computer. Open it in anything, hand it to a developer, or leave.
No GPrint server
No copy of your app, data or prompts on our side. Test data on your computer is never sent online.
Keys locked by your computer
GitHub and Railway sign-ins are encrypted by your computer — the keychain on a Mac, Windows' own data protection on a PC — and never sent to us.
A walled-off preview
Your app runs in a sandboxed browser, cut off from your files and your keys.
Signed on Mac. Unsigned beta on Windows.
On a Mac, every download and update is signed by us and notarised by Apple. The Windows version is a beta and not signed yet, so Windows asks you once before it runs.
What leaves your computer: crash reports (scrubbed, and off with one switch), a licence and update check, and the accounts you connect. Every detail.
GPrint Academy
Learn to build real apps with the AI you already have.
Short videos that show every step, and the decision behind each one. New ones as they come out.

Questions people ask
Do I need to know how to code?
No. You describe what you want in plain words. Your AI writes the code, and GPrint shows you what it built.
Which AI do I need?
Claude Code, Codex or Gemini, on the plan you already have. If you use something else, you can type its command.
Where is my app and its data?
On your computer, in a folder, until you choose to put it online. Online, it runs on your own Railway account.
Can I leave?
Yes. Your app is a normal folder. Nothing is locked inside GPrint.
Windows or Linux?
Windows, yes: Windows 10 and 11, as a beta for now. Linux comes later.
I lost my key.
