ArgoUML

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

ArgoUML is an open-source UML modeling tool that enables software developers, architects, and designers to create detailed UML diagrams for various purposes, including software design, system analysis, and documentation.

Developed in Java, the app is cross-platform, making it compatible with Windows, macOS, and Linux operating systems.

The app is a pure Java open source UML CASE (Computer-Aided Software Engineering) tool that provides cognitive support for object-oriented design. The tool is written entirely in Java and uses the Java Foundation Classes.

ArgoUML is compliant with the OMG Standard for UML 1.4. The core model repository is an implementation of the Java Metadata Interface (JMI) which directly supports MOF and uses the machine-readable version of the UML 1.4 specification provided by the OMG.

Highlights

Standard UML Metamodel
The app is compliant with the OMG Standard for UML 1.4. The core model repository is an implementation of the Java Metadata Interface (JMI) which directly supports MOF and uses the machine-readable version of the UML 1.4 specification provided by the OMG.

UML Diagram Support
It uses GEF, the UCI Graph Editing Framework to edit UML diagrams.

XMI Support
XMI is an XML based exchange format between UML tools. Argo UML uses this as a standard saving mechanism so that easy interchange with other tools and compliance with open standards are secured. Additionally, exporting the model to XMI is possible.

Several diagram export formats
Diagrams can be saved as GIF, PNG, PostScript, Encapsulated PS, PGML, and SVG.

Others Features
Advanced diagram editing and Zoom, OCL Support, Forward Engineering, Reverse Engineering /Jar/ class file Import, Cognitive Support, Reflection-in-action, and many more.

Key Features

Diagram Types: It supports various UML diagram types, including class diagrams, use case diagrams, sequence diagrams, activity diagrams, and more. This versatility allows users to model different aspects of their software projects.

Code Generation: It offers code generation capabilities, allowing you to generate code from your UML diagrams in multiple programming languages, including Java, C++, and more. This streamlines the development process and ensures consistency between your design and code.

Reverse Engineering: It can also reverse engineer existing code into UML diagrams, helping you understand complex legacy systems and make improvements.

Collaboration: The software facilitates collaboration among team members by supporting version control systems like Git. Multiple users can work on the same project concurrently.

Extensibility: It supports plugins, allowing you to extend its functionality to suit your specific modeling requirements.

Rich Palette: The software provides a rich set of UML elements, such as classes, interfaces, associations, and more, that can be easily dragged and dropped onto your diagrams.

Documentation: You can generate documentation directly from your UML diagrams, helping in project communication and knowledge sharing.

User Interface

ArgoUML's user interface is functional but may appear somewhat dated to users accustomed to more modern design aesthetics.

The interface consists of a menu bar, toolbar, diagram workspace, and various panels for navigating your project.

While it may not win any design awards, it is efficient and straightforward to navigate once you become familiar with it. The focus is clearly on functionality rather than aesthetics.
