App Builder
Describe an app.
Get a running one.
Frosone scaffolds the project, writes the files, starts the server and checks the page in a real browser. Not a code snippet: a running app.
Three steps
Scaffold
frosone create shop --template fullstack
Build
frosone --workspace shop "add a cart"
Verify
The agent opens the page, clicks the flow, fixes what breaks.
frosone create my-app --template static|node|fullstack
frosone --workspace my-app "build the first feature"What it can build
Static web app
HTML/CSS/JS, no build step. Good for landing pages, tools, dashboards.
Node API
Zero dependencies, health endpoint, ready to extend.
Fullstack
API plus frontend in one process. Add auth, data and deploy.
FAQ
Does it deploy for me?
Not yet. It builds and runs locally, then gives you the commands to deploy.
Which stack?
The smallest one that works. Static by default, Node with no dependencies when you need a backend. It follows an existing repo instead of rewriting it.
Can I use it on an existing project?
Yes. Open the workspace and ask for a feature; the agent reads the existing conventions first.
