Welcome to ZenUML™

Developers don't like drawing diagrams, what's the alternative?

There is already Visio, why do we bother to create ZenUML. Well, because I feel more comfortable with textual languages than with graphical ones.

With ZenUML, you can draw a perfect sequence diagram in less than 10 minutes. The diagram is stored in the cloud if you choose to log in. Otherwise, it is stored within your browser's storage.
