Structurizr

Structurizr is a modeling tool that allows software architects and developers to visualize, document, and explore their software systems. It uses a "code as data" approach, where models are defined in code and rendered as diagrams. It's primarily used by software architects, developers, and technical teams to communicate and understand the structure of their systems.
