OpenDesign vs Diagram Design
Bottom line
OpenDesign is a shared workspace where a brief becomes a prototype; diagram-design draws one diagram and stops.
Who it's for — Pick OpenDesign if several people review the same design system and refine a prototype together. Pick diagram-design if you want a single diagram as one file you can double-click, drawn in your brand colours and fonts.
Who it's NOT for — Skip OpenDesign if you only need one image; it expects a project and a design system. Skip diagram-design if you need motion, multi-screen flows or a coded interface.
One verifiable fact — 106,110 stars vs 65,287, both checked Nov 6, 2026 — about 1.6x.
Try / Skip — Try OpenDesign for team prototypes; try diagram-design for architecture, quadrants and sequence charts. Skip both if the deliverable is an app, not a visual.
