Data origin and collection

Last updated Apr 17, 2026 Web Analytics relies on the performance.getEntriesByType('navigation') object to collect metrics about page load performance. If Navigation Timing Level 2 is not supported, then performance.timing (Level 1) ↗︎ is used.

Refer to the W3C Processing Model ↗︎ for a visual depiction of the sequence of timing events for web page loads.

Data collection and reporting

Web Analytics collects the minimum amount of information - timing metrics - to show customers how their websites perform. Cloudflare does not track individual end users across our customers’ Internet properties.

The Web Analytics performance beacon loads from https://static.cloudflareinsights.com/beacon.min.js. You may need to update your Content Security Policy (CSP) settings to load this script.

Beacon data is sent to https://<yourdomainname>/cdn-cgi/rum for sites proxied through Cloudflare or https://cloudflareinsights.com/cdn-cgi/rum for sites not proxied through Cloudflare. Core Web Vital metrics are reported when the visibilityState is hidden for the first time after the page load event is triggered.
