How can this tool help me?

We built Core Web Vitals Checker so you can see how people experience your website without setting up complex dashboards or processes.

Core Web Vitals Checker reports four site speed metrics based on real Google Chrome browsing data. Each metric focuses on a different aspect of user experience, such as loading, interactivity and visual stability, so you know where to focus your efforts.

Where does the data come from?

Your summary is generated based on Google’s Chrome User Experience Report (CrUX)—a public dataset of real user experiences for millions of websites. CrUX collects data only for Chrome browser users who opted in (excluding iOS).

Data is updated daily and aggregates the previous 28 days of data.
