How this list is ranked. By total GitHub stars at the last daily refresh — a popularity signal, not a measure of quality, fit or safety. Star counts in the AI category are known to be inflated by fake-star campaigns, so each row leads with push activity and license instead. No commit in this collection has completed security review yet, so treat every entry as unreviewed discovery metadata.
