A blank canvas, an existing screenshot, or a text prompt describing what you want.
Drag, drop, and edit with real components — what you see is actual code underneath.
Generate layouts from screenshots or prompts, then refine by hand where it matters.
Ship clean React/Tailwind/CSS you can actually maintain, not a dead mockup.
Design directly on the canvas with real components and styles.
Screenshot-to-code and prompt-to-UI that produce editable results.
Exports are maintainable codebases, not locked-in proprietary files.
Multiplayer editing and commenting for teams.
Your design files live on your infrastructure.
No proprietary lock-in on your own work.
