Tools for creating Class Diagrams [closed]

Answer 1

Some time ago I used DIA - free and platform-independent. It was ok. Now I use Enterprise Architect but it's not free.

Answer 2

Just discovered GenMyModel, an awesome UML modeler to design class diagram online

Answer 3

I have used both Poseidon UML and Enterprise Architect and must say that I prefer Poseidon but wasn't fully satisfied with any of them.

Answer 4

I use GenMyModel, first released in 2013. It's a real UML modeler, not a drawing tool. Your diagrams are UML-compliant, generate code and can be exported as UML/XMI files. It's web-based and free so it matches your criteria.

Answer 5

Since all these tools lack a validation function their outcomes are just drawings and no better tool for creating nice drawings is a piece of paper and pen. Afterwards you can scan your diagrams and insert them into your team's wiki.

Answer 6

I used Poseidon UML Community Edition, it's platform independent and makes fine and clean diagrams. There are some screenshots here.
