StarUML


StarUML is a UML tool by MKLab. The software was licensed under a modified version of GNU GPL until 2014, when a rewritten version 2.0.0 was released for beta testing under a proprietary license.
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
The stated goal of the project was to replace larger, commercial applications such as Rational Rose and Borland Together.
StarUML supports most of the diagram types specified in UML 2.0. It is currently missing timing and interaction overview diagrams.
StarUML was written in Delphi, which is one of the reasons why it was abandoned for a long time. Since December 2005 StarUML was not updated anymore, although some external modules were updated
Currently the newest version of StarUML by the original authors is available for download under the handle "StarUML 2". The public beta is available, although not under the GPL license. Final price and new license type yet remains unknown. This version has been completely rewritten from scratch and includes among many features: support for extensions, OS X compatibility and a new graphical user interface.
