When redesigning my university’s 1,200+ page website Cacoo really came in handy for developing our site map. For a site of that size it was difficult to find a diagramming tool which would easily adapt to an evolving information architecture. We’re an all-Mac shop so that ruled out some options early on.
I found Cacoo’s drawing tools easy to use. It also has some pretty nice collaboration features so members of our team can contribute. Each map has a url that we were able to use to share with our vice presidents and various vendors involved in our redesign project.
The pricing structure is very generous. I was surprised by how much I could do with the free account. The Cacoo team upgraded our account for a year-long .edu free trial. I can definitely find more uses for this.
