Top Free & Open-Source diagrams Tools
7 distinct tools · sorted by coverage & stars
Notion and a whiteboard had one child, then let it keep files locally.
The same drawing engine, free: multiplayer, share links, libraries, local-first files, and end-to-end encrypted collaboration; cloud workspace management is leaner.
A persistent encrypted drive with collaborative whiteboards, folders, sharing, and access controls; less delightful drawing, stronger workspace bones.
A genuinely free hosted collaborative mind mapper with unlimited maps and useful imports and exports; tasks and presentation tricks are absent.
The obvious answer because it is the right one: broad diagramming, local ownership, imports, templates, and real-time collaboration through Google Drive or OneDrive.
A serious desktop mind mapper with outlines, formulas, attributes, filters, and local files; excellent depth, unmistakably utilitarian furniture.
Small, focused collaborative mind maps with a straightforward Docker install; public hosted maps expire, so permanence means self-hosting.
