Cloudflare publishes BEACON data on real-world web experience
BEACON provides a view of Cloudflare's browser and network telemetry to show how people experience the web beyond high-end devices and fast connections. Engineers can use real-user data to ground performance priorities in conditions their own setups may miss.
- What
- Cloudflare's BEACON is an anonymized dataset of real-world web performance measurements across 10,000 large websites.
- How
- It reports Core Web Vitals as full histograms, covers major browser engines, and is updated daily in Google BigQuery.
- Why it matters
- Engineers can inspect performance percentiles and long-tail experience across browsers, devices, and countries rather than relying on averages.
