How it works
Describe it
One sentence about the app you want. Plain language, no diagrams.
It gets built
The agent writes the code, sets up the database and wires the pages.
Publish it
One click puts it on a live URL. Connect your own domain when ready.
What you can build

A full-stack app with a database, pages and hosting.
