What is Cacoo?

Cacoo is a browser-based diagramming tool from Nulab, the company behind the Backlog and Typetalk collaboration products. It covers flowcharts, wireframes, UML, network topology and org charts through a large template library, and collaboration is the point: several people edit the same sheet at once, comment on shapes, leave sticky notes and follow a revision history. Diagrams live in shared folders with permissions, and integrations reach Google Drive, Confluence, Slack and other tools where diagrams are usually referenced. Its AI layer is thin, so treat it as a shared canvas for teams documenting systems and processes together.

FAQ

Do several people really edit at once?

Yes, the canvas is collaborative in the same way a shared document is. You see other cursors, can comment on a specific shape, and the revision history records who changed what and when.

Is there a diagram type it cannot handle?

Most standard business and technical diagram types are covered by templates. Highly specialised notations may need the shape library built by hand, or a tool dedicated to that notation.

Is Cacoo useful without a team?

It works as a single-user diagramming tool, but the free plan limits how many sheets you keep. Individuals usually compare it with draw.io or Figma before paying for seats.
