What is Designful?
Designful is an open-source, canvas-first SDK designed for teams that need to build serious design editors without rebuilding the canvas stack. It provides a Figma-style experience with features like auto layout, variables, snapping, and export, all powered by a modular and extensible architecture.
Built with TypeScript and Konva, Designful offers pixel-accurate snapping, alignment guides, and rulers that behave at any zoom. It includes production-ready capabilities such as history, storage, export, and performant rendering. The SDK is plugin-ready, allowing teams to extend behavior and integrate custom workflows seamlessly.
