What is LikeC4? Why “like”?
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.

@XAMTO_AI: Developers who write code will inevitably have to draw architecture diagrams. The most annoying part is manually dragging boxes and connecting lines — revising a version can make you question your life. LikeC4 generates software architecture diagrams directly from code; when the code changes, the diagram updates too, no more spending ages in Figma. It's based on the C4 Model and Structurizr DSL design…
