Describe the app you want. An AI agent builds it — full-stack, running, and previewed live in a sandboxed environment.
Plain-text prompts become complete applications — frontend, backend, and database — generated end to end.
Watch your app run in real time with a file explorer, command logs, and error monitoring as it builds.
Every turn is routed to the most cost-effective model that clears the quality bar — frontier answers without frontier bills.
