We maintained a c4 model of our systems built for importing and displaying on structurizr.com and tbh, it wasn't fun. You don't get the same intuitive understanding and overview from the code that you get from a diagram and there was no fast local preview. You had to upload your code to the server. Even worse was the fact that adding a new box usually meant realigning all arrows. As a consequence the diagrams were never kept up to date on a continuous basis.

I had a better experience using plantML for sequence diagrams. The task is easier so the output of the interpreter is typically useful without manual interventions.
