Cairn

Diagram-as-code CLI for generating logical, application, and infrastructure architecture views.

Desktopfreeglobal

Cairn is a free, open-source diagram-as-code tool specialized in generating logical, application, and infrastructure architecture views from code, with a CLI, a browser playground, and export to SVG or PNG. It's aimed at software architects who want their architecture diagrams version-controlled and code-generated rather than manually drawn and maintained in a separate tool.
