Questions
Can I build a Deno app with AI?
Yes. Pick one of 2 Deno templates — Deno HTTP servers — and describe what you want. The builder writes the code in a cloud sandbox with a live preview and a real terminal, using your own AI provider key.
Where can I deploy a Deno app built here?
Push to your GitHub repository and deploy to a host that runs Deno.
What happens when I press Start?
You sign up — or, if you are already signed in, go straight on — and the New Web App dialog opens with that template picked. Set the name, stack, design, model and MCP tools there, then press Create.
Do I own the code?
Yes. The project is pushed to your own GitHub repository, and you can open a terminal on it at any point.
