What it is

Cacoo is a diagramming and visual collaboration tool for teams creating flowcharts, wireframes, mind maps, workflows and technical diagrams.

It supports network, organizational, BPMN, component, deployment and AWS architecture diagrams. Users can share diagrams by public URL or shared folder, present them, embed them in websites and wikis, and protect them with passwords. Cacoo imports Microsoft Visio files and CSV. The Free plan supports PNG exports; paid plans add SVG, PDF, PS and PPT. Free includes unlimited users and six sheets, but limits exports and activity history.
