Popular UML Modeling Tools

Vote for your favorite UML modeling tool. There is no "best UML modeling tool". The best tool for project A is another than the best tool for project B. It depends on the different requirements of the projects. This list shows not the best, but the most popular tools if you vote for them. I've added all UML modeling tools I know and a short description taken from the tool vendor web sites. Please let me know if you want to add another one. See for a more detailed list.

Popular UML Modeling Tools | Poseidon for UML

Now Poseidon for UML is based on our Poseidon for DSLs platform. It is a great UML tool with a complete set of diagrams (class, package, use case, state, component, activity and sequence diagrams) and excellent user interface. We provide magnificent improvements in stability, scalability, performance, reliability and customization. We believe this tool has the best user interface in the industry. At the same time, it is an example of what is possible with our DSL platform. UML now is just one of the conceivable DSLs possible with the Poseidon for DSLs platform. A considerable part of the tool is generated from a handfull of models (MDSD). You, as the author of a DSL can simply change these models and by that create your own DSL modeling tool that shares the same user interface and performance characteristics as Poseidon for UML 8.0. Read on for our guiding principles.

EclipseUML architecture is composed of a live MOF to UML synchronization. Traditional UML Eclipse tools require 4 different stages which add unnecessary complexity. A sophisticated UMLproject developed with EclipseUML requires only a few hours before being able to produce advanced Java code, whereas over 3 months would be needed to produce beginner level java code using Eclipse modeling set of open source plugins. The new revolutionary Omondo architecture is built on the top of MOF and uses Ecore as opposed to traditional tools which use transformation layers.
