LikeC4 is a modeling language for describing software architecture and tools to generate diagrams from the model.
LikeC4 is inspired by C4 Model and Structurizr DSL, but provides some flexibility.
You customize or define your own notation, element types, and any number of nested levels in architecture model.
Perfectly tailored to your needs.
