About this app
OpenPencil is a modern, open-source alternative to Figma and Pencil, built specifically for AI-native design-to-code workflows. Describe any UI in natural language and watch it appear on an infinite canvas in real-time.
Key Features:
-
Prompt to Canvas: Describe what you want, and multiple AI agents will work simultaneously on different sections (like hero, features, footer) to generate the UI.
-
Multi-Model Intelligence: Automatically adapts to Claude, GPT-4o, Gemini, DeepSeek, Qwen, and Llama.
-
Design-as-Code: Files are saved as JSON, making them Git-friendly and easily exportable to React, Vue, Svelte, Tailwind, Flutter, and HTML/CSS.
-
Built-in MCP Server: Connect it directly to your favorite terminal agents like Claude Code or Cursor.
