Yup. Or a web app that I can point to an open-source repo.

Regarding C4, I'm no expert. I know the guys at IcePanel, an earlier YC-cohort company (https://news.ycombinator.com/item?id=34338995) that specializes in C4 diagrams, and they're very friendly, so if you haven't yet, they'll be much more equipped to chime in on C4 stuff.
