help Chrome UX Report (CrUX) FAQ
What is the difference between the Chrome UX Report and Lighthouse?
Lighthouse is a tool that simulates page load times in a controlled, laboratory environment using a single device profile. The Chrome UX Report (CrUX) is a public dataset that provides real-world metrics collected from millions of actual Google Chrome users. CrUX shows how real people on varying internet connections and devices actually experience a website.
What specific metrics are recorded in the Chrome UX Report?
The CrUX dataset primarily tracks Google's Core Web Vitals, which include Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID) or Interaction to Next Paint (INP). It also tracks standard page load metrics like First Contentful Paint (FCP). These metrics are recorded across desktop and mobile devices.
How often is the Chrome UX Report dataset updated?
The CrUX dataset is updated monthly, featuring data compiled over a trailing 28-day period. This lag ensures that sudden, temporary spikes in traffic or outages do not skew the overall historical performance. The data is available to query publicly via Google BigQuery or the PageSpeed Insights API.
Does the Chrome UX Report collect data from browsers other than Chrome?
No, as the name implies, the dataset only collects real-user metrics from the Google Chrome browser. It does not capture data from users visiting websites via Safari, Firefox, or Microsoft Edge. It also only gathers data from users who have opted-in to syncing their browsing history and usage statistics with Google.
