OpenPencil.dev

OpenPencil is a design editor that works directly with Figma files. You can open .fig files natively, copy and paste elements between Figma and OpenPencil, and edit your designs locally on your computer. It's built to be a practical alternative that doesn't lock you into a cloud service or require an account to get started.

What makes OpenPencil stand out is its dual nature. It's a fully-featured editor you can use right away, but it's also a toolkit for developers. The app includes a headless command-line interface for inspecting and exporting design files, a Vue SDK for building custom editors, and a built-in AI chat with over 90 tools for tasks like creating shapes or managing styles. It also supports real-time, peer-to-peer collaboration via WebRTC, so you can share a link and edit with others without a central server.

This tool is a great fit for designers who want more control over their tools and data, or who need to work offline. It's also useful for developers who need to automate design tasks, embed an editor into another product, or build a custom workflow around a design file format. Since it's open-source under the MIT license, teams can modify it to fit their specific needs without vendor lock-in.
