I know you store activities, so tracking anonymous metrics is not ideal in your data model but hear me out: There is no good solution at all anywhere on the web to easily track and analyze:
- GH downloads
- GH traffic stats
- GH registry image pulls
- Docker Hub image pulls
And I bet people would pay for someone to scrape these metrics, store them and make them analyzable. Because unlike GH stars, these metrics show real project signals and adoption. I think these metrics would be very powerful on your reports combined with other user-focused metrics.
