Modelio

Modelio provides an extensible environment for creating and managing models that conform to a variety of industry standards, including UML, BPMN, ArchiMate, SysML, and TOGAF. It offers diagram editors, consistency checking, and the ability to link elements across different model types, enabling analysts, developers, and architects to capture software, systems, and business‑process designs in a unified workspace.

The tool supports ArchiMate 3.2 with updated iconography and a downloadable extension, allowing users to represent enterprise‑architecture elements such as communication networks and facilities according to the latest specification. BPMN modeling is integrated and can be connected to UML diagrams, facilitating the inclusion of workflow definitions within broader architectural contexts. Additional features include formatted text and custom images in diagrams, as well as a traceability function that reveals all elements related to those already displayed.

Modelio is distributed as open‑source software, runs on macOS, and is positioned for stable, production‑grade use by teams that need a flexible, standards‑compliant modeling platform.
