PlantUML – draw UML diagrams

PlantUML creates diagrams from a concise textual description. This makes diagrams easy to keep alongside source code, documentation and other text-based project assets.

It covers the principal UML diagram types as well as many non-UML formats. PlantUML can be used from the command line, integrated into editors and documentation systems, or incorporated into automated workflows.

This is free and open source software.
