Structurizr is used for describing and visualizing architecture using the C4 model. One of the main selling points is the fact you can define an entire (IT) architecture model using text. A typical model consists of:

Recently been doing the same amongst our various teams since we have a mish-mash of Lucidchart, Miro, and other collaborative design tools.
One thing I was experimenting with (read: struggling with!) was a way to keep per-service (per-repo) architecture workspaces which are also synchronized on-commit to a central workspace and used !include to bind them together. The moving parts are not difficult - but writing your DSLs in a way that can handle this can be. This idea would let individual projects be self-sufficient and generate their own README doc diagrams as part of their own build process; but also have a central site which shows all the services as well as inter-service connectivity.
Did you ever consider https://github.com/avisi-cloud/structurizr-site-generatr to bring together your ADRs in with your architecture, or do you keep them separate?
