Visit pencil.dev.yoohoo.cn ↗What is OpenPencil?
OpenPencil is a design editor built on an open-source engine supporting `.fig` and `.pen` file formats, CanvasKit rendering, and a programmable SceneGraph. This fork by Yoohoo adds a React application shell, cloud document storage, and backend integration for business deployment. The repository describes it as an open-source Figma alternative.
The editor runs as a static web app with an optional Java backend for cloud features and OSS storage. It supports components, instances, layout systems, and can be self-hosted via Docker Compose. Development uses Bun, React, and TypeScript, with the core engine shared from upstream OpenPencil.
