Description
OpenPencil is a lightweight, open-source design editor designed for UI/UX prototyping and team collaboration. Built for developers and designers who need a native alternative to Figma without proprietary lock-in, OpenPencil lets you open, edit, and collaborate on `.fig` files directly—no server required. Its AI-assisted tools streamline repetitive tasks like shape generation and layout management, while real-time WebRTC collaboration ensures seamless multi-user editing. Whether you’re refining wireframes, managing design tokens, or automating exports (e.g., to Tailwind CSS), OpenPencil’s headless CLI adds flexibility. Available as a desktop or web app, it’s ideal for freelancers, agencies, and teams prioritizing open-source transparency and offline workflows.
