Beacon Commerce has not shipped a slow release in 6 months.
Beacon Commerce operates a headless commerce platform serving 12 million monthly shoppers. Every 100ms of LCP regression translated to measurable revenue loss. PagePulse's deployment impact diffing now blocks any release that regresses Core Web Vitals.
