Cacoo

Cacoo is a cloud‑based diagramming and collaboration platform that helps teams create flowcharts, wireframes, mind maps, network diagrams, and UML models. It enables real‑time collaboration, allowing multiple users to edit diagrams simultaneously, leave comments, and track changes.

It offers drag‑and‑drop diagramming, templates, revision history, and integrations with Slack, Google Drive, Confluence, and Dropbox. Cacoo also supports export options (PNG, PDF, SVG), presentation mode, and enterprise‑grade security, helping organizations visualize ideas, streamline workflows, and improve team communication.

And the best part? Cacoo is freemium — it offers a free tier with limited diagrams and collaboration features, while paid subscription plans unlock unlimited diagrams, advanced integrations, and team management tools. The entry paid plan starts at $6/month per user.
