BEACON opens a daily dataset of browser performance measurements

Cloudflare’s BEACON dataset makes aggregated browser-performance measurements available through BigQuery. It covers ten thousand large Cloudflare websites and includes loading, responsiveness and layout-stability metrics across browsers and devices. Daily updates and example queries let engineers investigate differences between groups, while removing site names and paths protects against exposing individual websites in the published data.

Why it matters

Web teams gain a public dataset for checking performance assumptions across environments.

More context

Try an example query for the browser and country mix relevant to your users. Review BigQuery’s query estimate before execution. The data normalises website volume and suppresses small groups.

Keep in mind

The selected Cloudflare sites are not a census of the web. Aggregated differences do not establish their causes, and they cannot replace measurements from your own application.
