Every week, FlagShark scans a curated list of public repos that use known feature flag SDKs. Sortable, filterable, and (if it's your repo) embarrassing. 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.
