## What it is
Modelio is an open-source visual modeling environment supporting standards like UML, BPMN, ArchiMate, SysML, and TOGAF for enterprise architecture, software development, and systems engineering. It provides diagram editing, model consistency checking, and extensibility via downloadable modules, written in Java.

## Use cases
- draw UML class and sequence diagrams
- model business processes with BPMN
- create enterprise architecture diagrams with ArchiMate
- model systems with SysML
- check model consistency across diagrams
- generate documentation from models
- apply TOGAF to enterprise architecture work

## When to choose
- you need a free open-source tool supporting multiple modeling standards (UML, BPMN, ArchiMate, SysML)
- you want to link business process models with software architecture models
- you need model consistency checking and traceability in diagrams
- you want an extensible modeling environment with downloadable modules

## When to avoid
- you need lightweight text-based diagramming like PlantUML or Mermaid
- you require a web-based collaborative modeling tool
- you need commercial support or advanced proprietary features
- you only need simple flowcharts rather than standards-based modeling

## Facets
- artifact type: application
