LikeC4

What is LikeC4? Why "like"?

LikeC4 is a modeling language for describing software architecture, and tools to generate diagrams from the model.
Inspired by C4 Model and Structurizr DSL, but with some flexibility.

You define your own notation, custom element types and any number of nested levels in architecture model.
Perfectly tailored to your needs.
