Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.
