StarUML – The Open Source UML/MDA Platform

StarUML is an open source project to develop a fast, flexible, extensible, full-featured, and freely-available UML 2.0/MDA platform running on the Win32 platform. The goal of the StarUML project is building a software modeling tool and platform that’s a compelling replacement for commercial UML tools, such as Rational Rose, Together, and so on.

MDA (Model Driven Architecture) is a new technology introduced by the Object Management Group (OMG). To get the advantages of MDA, a software modeling tool should support many customization variables. StarUML supports MDA, and provides numerous customization variables.

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.

Visual Paradigm for UML

Visual Paradigm for UML (VP-UML) is a UML design tool and UML CASE tool designed to aid software development. VP-UML supports key industry standards such as Unified Modeling Language (UML), SysML, BPMN, XMI, etc. It offers complete toolset software development teams need for requirements capturing, software planning, test planning, class modeling, data modeling, and etc.

Module: UML Designer

UML Designer is the easiest UML2 tool to make nice-looking diagrams. It’s integrated into Eclipse, opensource, and supports all the diagrams of UML2 standard.
As it is based on Obeo Designer, it provides an easy way to combine UML with domain specific modelling. You can extend the provided diagram definitions and seamlessly work on both UML and DSL models at the same time.


ArgoUML is the leading open source UML modeling tool and includes support for all standard UML 1.4 diagrams. It runs on any Java platform and is available in ten languages.


MetaEdit+ enables companies to radically improve development productivity and quality by generating full code directly from models. First you design the modeling language with MetaEdit+ Workbench and then other developers model with the language in MetaEdit+ Modeler.

Altova UModel

Altova UModel® 2013 is the starting point for successful software development. Visually design application models in UML and generate Java, C#, or Visual Basic .NET code and project documentation. Or, reverse engineer existing programs into UML 2 diagrams, then fine tune your designs and complete the round trip by regenerating code.

AnyLogic is the only simulation tool that supports all the most common simulation methodologies in place today: System Dynamics, Process-centric (AKA Discrete Event), and Agent Basedmodeling.


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.
