Gaphor

Simple UML and SysML modeling tool

Gaphor is a UML, SysML, RAAML, and C4 modeling application. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool. You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models.

Gaphor provides four modeling languages: UML, SysML, RAAML and C4 and makes them accessible to beginners.
