FlagShark scans a curated list of public repos that use known feature flag SDKs. Sortable, filterable, and (if it's your repo) embarrassing. One caveat up front: these counts include flag references in test fixtures and example code, so the raw totals overstate genuine production debt. Public MIT/Apache repos only, no opt-in required. If you're a maintainer and want off the list, email us and we remove within 24 hours, no questions asked.

Honest about the limits. If you're a maintainer of a listed repo and find a finding incorrect, every row has a "report" link, or you can ask us to remove the repo entirely.
