Designful is an open-source, Figma-style canvas SDK for developers. Ships snapping, alignment guides, history, layering, export and auto-layout out of the box, with plugin support for teams building their own custom design-editor tools.
Open source and free to use as an SDK.
Developers building a custom in-house design or canvas editor who don't want to build precision drawing tools (snapping, guides, layering) from scratch.
This is a developer SDK, not an end-user design app: relevant only to teams building their own design tool, not to designers looking for a Figma-style app to use directly.
Free design tool with no ads, no signup, and privacy first.
