Structurizr

The Structurizr DSL (as mentioned on the ThoughtWorks Tech Radar) enables you to create software architecture models based upon the C4 model, using a textual domain specific language (DSL). The DSL allows you to create multiple diagrams in multiple output formats, from a single DSL source file.

This is a demo page, and some features are unavailable (!include, !docs, !adrs, element style icons, branding logo). The Structurizr DSL is designed to be used in conjunction with the Structurizr CLI.
