What it is
Cacoo is a web-based diagramming and visual collaboration tool for building flowcharts, wireframes, mind maps, workflows, and technical diagrams. It supports real-time editing and diagram types such as network diagrams, organizational charts, BPMN, component and deployment diagrams, and AWS architecture diagrams. Its workspace includes templates, shapes, sticky notes, a media library, an infinite canvas, tables, and dynamic charts. Diagrams can be shared through public URLs or shared folders, presented, embedded in websites and wikis, or password-protected. Cacoo imports Microsoft Visio files and CSV. The free plan allows unlimited users and six sheets, with PNG export; Pro and Team are $6 per user per month, billed monthly, and paid plans offer a 14-day trial without a credit card. Paid exports include PNG, SVG, PDF, PS, and PPT. Cacoo also offers API access, integrations, enterprise security controls, and private-server hosting. Enterprise private-server licensing is $1,500 a year for 10 users.
