Diagramming needs vary by the kinds of visuals you make and how you prefer to edit them. Compared on diagram types, import/export formats, offline editing, real-time collaboration, desktop apps, editor seat limit, free plan, and paid from, the entries give you practical points for assessing individual or team use. EdrawMax, Creately, and draw.io are among the options shown, alongside Ilograph and Cacoo. Consider which diagram types and file formats matter to your work, then weigh offline access and collaboration against seat limits, desktop availability, and pricing.
45 diagramming software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
