Hey Tegan, are you looking for "pulse" that's more dev focused or ops focused?
There a few tools like Pluralsight Flow and Code Climate that focus on git specific metrics (e.g., time to merge, developer velocity, etc.)
On the ops side of things, if it's a bunch of repos feeding into a larger service, you may want to look at a service catalog offering. This kind of tooling shows what's running in production, who owns it, and how healthy it is. Open source offerings are Backstage (by Spotify) and Clutch (by Lyft). There are also SaaS options available like OpsLevel.
