Papyrus UMLLight

Papyrus UMLLight is a simplified UML modeling tool based on Papyrus that exposes only the most common concepts and diagram types of UML.


  • Streamlined user interfaces for creating, viewing, and editing UML Use Case Diagrams, Activity Diagrams, Class Diagrams, State Machines, Package Diagrams, and Sequence Diagrams.
  • Simplified subset of UML including only the most common modeling concepts of UML, largely following OMG's foundational level of a certified UML Professional 2 (OCUP 2)
