Pros

  • Native vector transfer to Figma via keyboard shortcuts without requiring plugins
  • Official MCP server support for generating and editing screens straight from AI coding IDEs
  • Exports clean, production-ready React, TypeScript, and Tailwind CSS code instead of static bitmaps
  • Flexible hybrid editing combining natural language chat tweaks with direct manual canvas controls

Cons

  • Copying to Figma relies on browser clipboard access and fails if you switch tabs while the asset is preparing
  • Batch generation and simultaneous prompt editing are capped at a maximum of 6 screens per request
  • Code export is limited to declarative UI markup without state management or backend business logic
