Instant Club: a public leaderboard for fast websites

Field notes

The page combines an individual URL check with a public performance index organized around a 1.5-second phone LCP cutoff. It reports 42 club members out of 166 measured sites, publishes percentile context including a 2.1-second median and 7.7-second p99, and separates contenders from pages with large transfer sizes. The interface also records weekly movement, including 39 joiners and no sites kicked out since Monday.
