OpenPencil

What is OpenPencil?

Design editor that opens Figma files, with an AI chat, a CLI and an MCP server for agents.

Who is OpenPencil best for?

OpenPencil is best for designers and design engineers who want to edit Figma files in a free app that agents can script.

• Teams leaving Figma

  It reads and writes native .fig files and lets you copy and paste nodes between OpenPencil and Figma.

• Design work driven by AI agents

  An MCP server, a headless CLI and guided setup for Claude Code, Codex and Gemini CLI let agents create and edit designs.

• Design system audits

  The CLI lints naming, layout and accessibility and pulls colors, type scale and spacing tokens out of a file.

• Handing designs to developers

  Selections export as Tailwind JSX, HTML or Storybook stories, as well as PNG, SVG and PDF.

How much does OpenPencil cost?

OpenPencil is free under the MIT licence, with desktop, web and CLI versions; its Cloud server is free to self-host, and the hosted Cloud service has only a waitlist so far.

There is no paid plan. A hosted OpenPencil Cloud takes waitlist sign-ups but has no published price. AI features use your own provider key or coding-agent subscription, and donations go through Ko-fi. Full pricing on github.com. We checked these prices on 8 Nov 2026.
