Core Web Vitals History
Core Web Vitals History provides a visual interface to analyze website performance trends by fetching historical data from Google's Chrome User Experience (CrUX) API. Unlike standard performance tools that show current metrics, this utility displays data from the past six months, enabling developers to correlate performance regressions or improvements with specific infrastructure or code changes. It relies on real-user metrics aggregated by Google for URLs with sufficient traffic.
