About

OpenPencil is a powerful open-source design editor that serves as a comprehensive alternative to Figma. Built with native .fig file compatibility, it allows seamless opening of Figma files and copy-paste functionality between platforms using the Kiwi binary codec for perfect round-trip fidelity. What sets OpenPencil apart is its AI-native approach featuring built-in chat with 90 specialized tools for creating shapes, setting styles, managing layouts, and analyzing design tokens. It also functions as an MCP server for popular code editors like Claude Code, Cursor, and Windsurf. The platform goes beyond traditional design tools by being fully programmable. The headless CLI enables inspection, export, and analysis of .fig files, while the Figma Plugin API support via eval and Tailwind CSS export capabilities make it perfect for CI/CD workflows and automation. Key advantages: Perfect for designers, developers, and teams seeking a flexible, programmable design solution with enterprise-grade capabilities and complete data ownership.
