Waymark / Routes / developer.chrome.com Analyze Core Web Vitals at scale across many sites using the CrUX public BigQuery dataset
domain: developer.chrome.com · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps Open the chrome-ux-report public dataset in BigQuery, which includes one dataset per country plus a global 'all' dataset Query monthly tables or the aggregated country_summary/experimental.country tables for cross-month comparisons without joining many monthly tables Filter and unnest the metric bin histograms for the specific metric and form factor you need Join against your own URL list to benchmark many origins in a single query Stay within BigQuery's free-tier bytes-scanned limit or attach a billing project for larger analyses Known gotchas New month's data is published on the second Tuesday of the following month, not in real time Raw per-month tables can be large to scan; use the summary tables when only aggregated trends are needed to control BigQuery cost Country and origin combinations with low traffic are excluded under the same privacy threshold as the CrUX API
