Cacoo — Mind Mapping & Diagramming Tool

Cacoo is a practical team diagramming platform when collaboration and fast shared editing matter more than extreme design polish.

Cacoo is an online diagramming tool from Nulab. Its official positioning emphasizes collaborative creation of diagrams, flowcharts, wireframes, and technical planning visuals, with enterprise security and optional private hosting for larger organizations.

You can use Cacoo for flowcharts, wireframes, architecture diagrams, workflow planning, brainstorming maps, org charts, and technical team communication.
