The CrUX dataset on BigQuery is updated on the second Tuesday of every month. Each release is numbered according to the year and calendar month of the data collection period, for example 201912 corresponds to the UX data collected during December 2019 and would be released on the second Tuesday of January 2020 after the data collection period has ended.
In the following list, we've curated some release notes for each monthly dataset. Subscribe to our CrUX Announce mailing list or follow @ChromeUXReport on Twitter for release Announcements.

June 2026
Publication date

May 2026
Publication date
- June 09, 2026
What's new
- We see a regression in pass rates this month, mostly on Android. We have a few suspicions as to why this might be but nothing definitive to share yet.
- We had a slight delay to yesterday's weekly release to the CrUX History API and CrUX Vis. This is now resolved. It was unrelated to today's monthly release.

January 2026
Publication date
- February 10, 2026
What's new
- As noted last month, there is always a high variability in December data for seasonal reasons so we included the comparison to November data this month as well, where we see a reversion to form with a good increase over the two months in INP, CLS, and particularly overall pass rates and a slightly lesser change in LCP.
Notable stats
- 18,412,653 origins (↑ 6.9%) (↓ 0.1% from Nov data)
- 68.3% of origins (↑ 1.1%) had good LCP (↑ 0.4% from Nov data)

- 55.7% of origins (↑ 2.3%) have good Core Web Vitals (↑ 2.0% from Nov data)
December 2025
Publication date
- January 13, 2026
What's new
- We usually see a high variability with the December data—we have seen the same every year since CrUX launched. Given the high variability it's difficult to attribute any of these moves to any particular causes and we expect most numbers to revert back next month (again as they mostly have in previous years). Therefore, we won't try to explain these movements this month.
Notable stats
- 17,288,655 origins (↓ 6.5%)
- 67.6% of origins (↓ 0.5%) had good LCP
- 80.3% of origins (↑ 0.1%) had good CLS
- 85.6% of origins (↓ 0.6%) had good INP
- 54.4% of origins (↓ 0.4%) had good Core Web Vitals
November 2025
Publication date
- December 9, 2025
What's new
- A final reminder that we've deprecated the CrUX Dashboard at the end of November. It has not been updated for this month and we will shut down the connector soon.
Notable stats
- 18,426,351 origins (↓ 0.1%)
- 68.0% of origins (↑ 0.3%) had good LCP
- 80.2% of origins (↓ 0.1%) had good CLS
- 86.2% of origins (↑ 0.3%) had good INP
- 54.6% of origins (↑ 0.5%) had good Core Web Vitals
October 2025
Publication date
- November 11, 2025
What's new
- A reminder that we are deprecating the CrUX Dashboard at the end of November. As the October dataset is the last month before that data, we are now stopping updating the data in the CrUX Connector that powers this dashboard and any similar dashboards you may have created based on this. The November data (released in December) won't be included. And we will shut down the connector soon.
Notable stats
- 18,438,315 origins (↓ 1.4%)
- 67.7% of origins (↑ 0.2%) had good LCP
- 80.3% of origins (↑ 0.2%) had good CLS
- 85.9% of origins (↓ 0.1%) had good INP
