You're in charge
You decide what makes it in.
Qyant shows you a clean, side-by-side view of everything it wants to change. Read it, keep what you love, set aside what you don't — file by file. Nothing lands in your project until you say yes. And if you ever change your mind, your full history is right there to roll back to.

The whole thing
Real full-stack apps.
From your very first prompt, Qyant builds a complete app — the interface, the logic behind it, and a real PostgreSQL database — all running live in its own space. What you see in the preview is the real app working, ready to grow with you.
Interface, backend, and database together.
A real Postgres database for every project.
A live preview that's the actual app.

Built like infrastructure
Serious enough for the apps you actually rely on.
Generated code runs somewhere. Here, it runs in isolation, against its own database, behind previews only you can open — and every line lands in a repo you own.
Kernel-isolated sandboxes
Every project runs in its own container under gVisor — a user-space kernel between generated code and the host. Capabilities dropped, hard CPU, memory and process limits, no privilege escalation.
A private Postgres per app
Each project gets its own database and its own credentials, provisioned automatically and wired into the app's .env. One app can never read another's data.
Previews only you can open
preview--your-app.apps.qyant.dev answers to the project owner alone. Secrets in .env are never shown to the model and never pushed to GitHub.
Every change reviewed, every version kept
The model proposes; you accept or reject file by file, with a real diff. Each accepted change is a version you can roll back to at any time.
Your repo, your code
One-click sync to a GitHub repository you own. Export everything, any time — there is no lock-in in the way the code is written.
Deploy to your own URL
Ship to your-app.apps.qyant.dev over HTTPS in one click, with the same isolation as the preview and the database that goes with it.
How it works
Three steps to a live app.
The same loop every time, whether it's the first prompt or the five-hundredth.

Describe it.
Say what you want to build, in your own words. Qyant reads your whole project first, then plans the change — schema, routes, UI — before it writes a line.
Build an invoicing app for my agency: clients, invoices with line items, PDF export, and a dashboard of what's overdue.

Review it.
Every change arrives as a diff, file by file, with the live preview already running the new code. Keep what you like, reject the rest. Nothing lands without you.
