But in this case the no-cost value is exactly zero, nada, zilch! Please, guys, be honest and admit that you want to make money and don't try to pretend you care about the community. Registration at the website is required in order to get a licence key file.
So far I haven't found any defects or usability issues. It is actually a pleasure to work with this tool, even when it comes to fiddling with relationship labels and lines. Negative remarks: The limitation of the community edition is that you can only create one diagram per diagram type per project. As soon as you create a second class diagram, for instance, all exported images are severely watermarked to the effect that they become almost unreadable.
Verdict: Perfect, except for the crippling just-one-diagram-per-type limitation. UMLet Version tested: Relationship labels roles, multiplicity are automatically placed and cannot be manually moved. In mild cases the result is visually unappealing, but often a label becomes partially obscured because the relationship line goes right through it. Supports diagram types other than class and sequence diagrams: Yes activity, deployment, use case and others Mac OS X: Yes, is a Java app.
Is also available as an Eclipse plugin. Runs as non-privileged user: Yes English UI: Yes Positive remarks: UMLet is very unorthodox in that it uses a markup syntax to define the appearance of a shape: Instead of clicking through many GUI dialogs to change the various properties of a shape, the shape has only one property: The markup text. Changing the markup immediately changes the shape's appearance.
At first I found this approach very disconcerting, but to my astonishment I got quite used to it after a few shapes. I guess that if you know the markup syntax in depth, working with UMLet will become a breeze. This becomes especially apparent after working with "large" products. Negative remarks: One diagram per file Verdict: Not too bad, despite its bare-bones GUI and the slightly weird markup approach.
I prefer UMLet over Dia. Modelio Version tested: 2. Modeliosoft, the company behind this tool, sells commercial add-on functionality plugins. Rearrange diagrams: Not too bad Customize relationship appearance: Poor. Customizing where relationship endpoints and labels are drawn is very tedious Supports diagram types other than class and sequence diagrams: Yes activity, deployment, use case and others Mac OS X: No Runs as non-privileged user: Yes English UI: Yes Positive remarks: No apparent limitations: If a feature is there, it is not crippled at all.
Eclipse-based GUI, which is a plus if you are familiar with Eclipse. Negative remarks: Sequence diagram: Execution specifications on the same lifeline do not overlap. Usability and workflow in general could be improved.
For instance, creating a new class or operation in a class diagram should let me name that class or operation immediately. Another one is that adding a new message should let me choose from existing operations immediately. In these examples, instead of helping me with the logical next step in the workflow, Modelio forces me to manually initiate the next step, and usually I need the mouse for this.
This makes working with Modelio much less enjoyable than it could be. Verdict: Not too bad, feature-wise, because this is a real modeling tool with no crippling limitations and an attractive-looking GUI. The main problem of this tool are its usability issues! Open ModelSphere Version tested: 3.

So if you need it for commercial purposes and your employer won't spring for that then I'd really be looking for a new job really quickly.
The only thing we haven't looked into yet is multi-developer support, which all the expensive tools are able to do. But from the web-site it seems like they support it. I use a licensed version of Visual Paradigm at work. There is a free community edition that should be able to handle most of your basic UML needs.
