StarUML is a cross-platform software modeler designed for visualizing system designs. It supports a variety of modeling languages, including UML 2, Entity-Relationship Diagrams (ERD), and the C4 Model, allowing users to maintain different architectural views in one project.
The tool is intended for architects and developers who require a structured approach to system design. It includes specialized diagrams and a JavaScript-based extensibility system that allows for the development of custom extensions.
Additionally, the software supports AI integration via an MCP server and provides extensions for code generation in languages such as Java, C#, C++, and Python. It also supports the use of Mermaid syntax for diagram generation.
Buyers should confirm whether they require the basic UML and ERD tools found in the Standard version or the advanced architecture and wireframing languages available in the Professional version.
Key Features
