Core Web Vitals Technology Report
The latest Core Web Vitals Technology Report unveils the premier content management systems (CMS) ranked by Core Web Vitals (CWV) metrics for June, as July’s statistics are not yet available. Notably, an e-commerce platform has emerged as a surprising frontrunner this year. This accomplishment is significant, given that e-commerce sites often falter in performance due to the myriad of JavaScript and image loads integral to their functionalities.
This analysis also encompasses Interaction to Next Paint (INP) scores, which diverge from the traditional CWV metrics. INP specifically gauges the speed at which a website visually responds following user interaction. The term “next paint” symbolizes the instance when the browser autonomously refreshes the page’s visual output in reaction to a user’s command.
A subpar INP score can precipitate user dissatisfaction, as it may lead to the perception of a sluggish or unresponsive site. Conversely, a commendable INP score is indicative of enhanced user experience owing to rapid site performance.
Data Sources Integrated in the CWV Technology Report
The report amalgamates two prominent public datasets:
- Chrome User Experience Report (CrUX)
- HTTP Archive
1. Chrome User Experience Report (CrUX)
CrUX compiles data from Chrome users voluntarily participating in usage statistics reporting while navigating over 8 million websites. This information incorporates performance metrics related to Core Web Vitals, aggregated into monthly datasets.
2. HTTP Archive
HTTP Archive leverages lab tests conducted by tools like WebPageTest and Lighthouse to evaluate how websites are constructed and whether they adhere to optimal performance standards. The union of these datasets illustrates the operational efficacy of websites and the technological frameworks underpinning them.
The CWV Technology Report fuses data emanating from HTTP Archive—utilizing laboratory-based crawling and evaluation—with CrUX, which collates genuine user performance metrics from Chrome browsers. This intersection forms the basis for the Core Web Vitals performance outcomes of various content management systems.
The Pinnacle of Core Web Vitals Performers
Currently reigning as the top-performing content management system is Duda, with an impressive 83.63% of its websites achieving commendable CWV scores. Duda has consistently secured the #1 position, continuing this trend into the current month.
When assessed for Interaction to Next Paint scores, however, Duda slips to second place.
Second Place in CWV: Shopify
Occupying the subsequent rank is Shopify, with 75.22% of its websites receiving favorable CWV scores. This is particularly striking, as online shopping platforms are commonly encumbered by the hefty JavaScript demands necessary for features such as product filters, sliders, image effects, and other utilities that facilitate purchasing decisions. Nevertheless, Shopify appears to have adeptly navigated these challenges, consistently outpacing competitors like Wix and WordPress.
In terms of INP rankings, Shopify claims the third position, residing at the upper tier of performance.
Third Place For CWV: Wix
Wix ranks third, closely trailing Shopify, with 70.76% of its websites garnering good CWV scores. Notably, 86.82% of Wix sites achieved commendable INP scores, positioning them fourth for this specific metric.
Fourth Place: Squarespace
With 67.66% of Squarespace websites receiving favorable CWV scores, the platform finds itself in the fourth slot, merely a few percentage points behind Wix. Remarkably, Squarespace excels in INP performance, achieving the highest score of 95.85% of its sites reflecting good responsiveness, signifying a superior user experience.
Fifth Place: Drupal
Drupal occupies the fifth position, with 59.07% of its sites achieving commendable CWV scores. While this figure falls short of Duda’s impressive 83.63%, it surpasses that of WordPress.
However, in terms of INP ratings, Drupal languishes at the bottom, with only 85.5% scoring well in that regard.
Sixth Place: WordPress
With a mere 43.44% of WordPress sites attaining satisfactory CWV scores, the platform trails significantly behind Drupal by over fifteen percentage points. Thus, WordPress is not only last in CWV performance, but it does so with a marked margin.
The performance of WordPress has not exhibited improvement this year, commencing 2025 at 42.58%, only to inch upward to 44.93% in April before retreating to 43.44% by the end of June—frustratingly near its starting point.
For INP scores, WordPress finds itself in fifth place, with 85.89% of its sites achieving satisfactory metrics—merely 0.39 points above Drupal. It is worth noting that WordPress began the year with an INP score of 86.05%, yet concluded June with a minor decline.
INP Rankings by CMS
Below are the rankings for INP performance, showcasing the percentage of sites exhibiting commendable INP scores adjacent to each CMS:
- Squarespace – 95.85%
- Duda – 93.35%
- Shopify – 89.07%
- Wix – 86.82%
- WordPress – 85.89%
- Drupal – 85.5%
Notably, the rankings for positions three through six are closely clustered within the eighty percent realm, indicating only a 3.57 percentage-point discrepancy separating the lowest-ranked Drupal and the third-positioned Shopify. This suggests that all mentioned content management systems are commendable performers regarding INP scores. Shopify, in particular, has achieved recognition for second place in CWV and third for INP—indicative of its robust performance.
