This web site presents a list of free, open source and commercial Unified Modeling Language (UML) tools, that can be used to model systems and software architecture using the UML diagrams: Activity diagram, Class diagram, Communication diagram, Component diagram, Composite structure diagram, Deployment diagram, Interaction overview diagram, Object diagram, Package diagram, Sequence diagram, State diagram, Timing diagram, UML state machine, Use case diagram. Some of the tools presented here are independent UML tools that can be used on a desktop computer or online, other are UML plugins that should be used with an IDE like Eclipse. The Unified Modeling Language (UML) is a modeling language for system definition standardized by the Object Management Group (OMG). It is used mainly for requirements, architecture and design software development activities. The UML has been created by Grady Booch, Yvar Jacobson and and James Rumbaugh in the 90s combining existing techniques and models from data modeling, business modeling, object modeling and component modeling.
