StarUML Download – Free UML Diagram Tool 4.0.1.0
146 MB (Safe & Secure)
StarUML free UML diagram tool is an open-source project to develop a fast, flexible, extensible, full-featured, and freely-available UML/MDA platform running on a Win32 platform. The goal is a compelling replacement of commercial UML tools such as rational rose, It is a software modeling platform that supports UML (Unified Modeling Language). It is based on UML version 1.4 and provides eleven different types of diagrams, and it accepts UML 2.0 notation. It actively supports the MDA (Model Driven Architecture) approach by supporting the UML profile concept. StarUML excels in customizability to the user’s environment and has high extensibility in its functionality. Using StarUML, one of the top leading software modeling tools will guarantee to maximize the productivity and quality of your software projects.
StarUML is one of the programs that was created to provide all the necessary components and functions for creating and editing projects that support the Unified Modeling Language (UML) standards and, consequently, are compatible with the Model-Driven Architecture (MDA) specifications.
After being abandoned for some time, the project had a revival to move from Delphi to Java/Eclipse and then stopped again. In 2014, a rewritten version was released as proprietary software. However, the open-source version’s community is still active and Many topics are discussed on the forums.

StarUML Diagrams Software FAQs
Is StarUML open source?
No. StarUML V1 was an open source project under GPL License. However, current StarUML (after V2) is not open source any more. Many users have been expected that the project is being continued, developed and maintained. But, we couldn’t find any sponsors so we can’t avoid to commercialize this product in order to keep developing and supporting users.

Can I still use StarUML V1?
Yes. you can use StarUML V1 for any purpose. However, don’t forget that the StarUML V1 is no more maintained and cannot be supported.

License is perpetual, so you can use forever with the purchased version. However, you need to pay to upgrade to new major versions.

What is the difference between evaluation and purchased license?
In evaluation mode, there will be watermarks in the exported diagram images. There is no time limit for evaluation, but it is only allowed for evaluation purpose. If you want to use for other purposes including educational, personal, or commercial purpose, you need to purchase licenses.

Conclusion
StarUML has many powerful features and is certainly more than a “simple” diagramming tool. With its support of MDA (Model Driven Architecture), it is more aimed at people using UML in an intensive way and with some code generation objectives than simply drawing diagrams to document requirements. However, using StarUML just as a diagramming tool works fine, especially on Windows as the tool is built with Delphi and might execute faster than the Java-based tools.
