About Cacoo
Cacoo is a browser-based diagram editor made by Nulab, the Japanese company behind the Backlog project tool. It covers flowcharts, wireframes, network and cloud diagrams, mind maps, org charts and similar business visuals, with real-time co-editing, comments and video chat on the canvas. Its selling point is price: the free plan allows unlimited users with a cap on the number of sheets, and paid Pro and Team plans are noticeably cheaper per user than Lucidchart. It connects to Backlog, Slack, Google Drive, Confluence, Microsoft Teams and others, and recent versions add AI helpers such as text-to-graph. Cacoo is web-only, the shape libraries are smaller than the big players, and advanced features like data linking are thin. It suits small teams and schools that want straightforward shared diagrams at a modest cost, especially ones already using Nulab's other tools.
Best for: Small teams and classrooms wanting cheap, shared online diagrams.
