Look4Sat vs Nightwatch
Two tools side by side on stored numbers and facts. No verdict of ours: every number (stars, gains, last commit, contributors) carries the time it was checked, licence and platform are copied from each entry, and a missing value reads [unconfirmed].
AI chooses the lists under the owner’s delegation. No human review is running in September 2026. Total stars, increases, cross-source signals, last updates and licences are shown as evidence. How ranks work →

Star totals are the last GitHub check plus increases observed via GH Archive since; the 7- and 30-day gains are GH Archive observations to the reference time. The same snapshot as the rankings — a comparison, not a recommendation.
WHICH FOR WHOM
The roles are copied from each entry’s "who uses it" lines. Nothing here is a new judgement.
