A simple editor for PlantUML. Requires PlantUML (and its dependencies, java and graphviz/dot).

Some features:

  • update the diagram while editing
  • code assistant to insert ready-made code snipets
  • written in Qt, so it should run on all platforms supported by Qt and PlantUML
  • option to cache the PlantUML output to speed redo, undo and loading from disk
  • can be used as a PlantUML viewer (see the wiki for more info)
