crystal-facet-uml is a desktop UML and SysML modeling application designed to document system and software architecture from multiple viewpoints.
It helps architects build a consistent set of diagrams by keeping element names, hierarchies, relationships, and shared model data aligned across the project, while storing that data in a JSON-based format that can be versioned alongside source code.
This is free and open source software.
Key Features
- Creates, modifies, and deletes UML and SysML diagrams, elements, and relationships.
- Maintains a shared meta-model so elements and relationships stay consistent across multiple diagrams.
- Supports part-automatic layout, with user control over messages and transitions in sequence and timing diagrams.
- Exports diagrams and models to SVG, PDF, PS, PNG, HTML, DocBook, JSON, and XMI formats.
- Offers both a graphical interface and command line operation for batch export, JSON import, and checking or repairing model files.
