> Describe an app and AI builds it, hosts it and gives you a link to share. Use our agent or your own: Claude Code, Codex, Cursor. Free, no sign-up.

An app is a snippet of C# whose GenHTTP handler is served at a public HTTPS address. An agent creates, changes and deploys it through the MCP server or the REST API below.
