The 202503 dataset is live

Hi CrUX users,

This is your monthly announcement that the latest dataset has been published to BigQuery.

The 202503 (March 2025) dataset is now available and it covers 18,473,760 origins, a decrease of 1.2% over last month.

Here's a look at origins' Core Web Vitals performance this month:

• 67.9% of origins (↑ 1.8%) had good LCP

• 78.2% of origins (↑ 0.5%) had good CLS

• 85.8% of origins (~ 0.0%) had good INP

• 52.8% of origins (↑ 2.1%) had good LCP, CLS and INP

We noticed good improvements to LCP and overall good origins this month, which look to be down to improved bfcache eligibility thanks to some fixes by the Chrome team to make more APIs compatible with the bfcache.

In other CrUX news, the Chrome DevTools team has been busy adding CrUX field data to the Performance panel in the live metrics view and in the trace view including the LCP subparts. We hope that makes it easier to understand the performance issues experienced by your users in context of your local debugging.

Last year, we launched CrUX Vis as an experimental new tool to visualise CrUX Data and potentially replace the CrUX Dashboard. This has been received very well and we’re removing the experimental status of this tool over the coming months and also coming up with a plan to deprecate and eventually remove the CrUX Dashboard. As many of you are aware, the dashboard has suffered from stability issues as CrUX usage of it has scaled. We’d ask you to continue to provide CrUX Vis feedback using the CrUX Vis survey or the CrUX discussion group and we’ll share CrUX Dashboard deprecation timelines soon.

Finally, the community shout out this month goes to Calibre who, along with upgrading their free CrUX tool, also created Website Speed Performance Leaderboards for various industries based on CrUX data. How does your company or brand compare stack up?

Cheers,

Barry
