Top 6 CMS For Core Web Vitals

Core Web Vitals Technology Report names which CMS have the best CWV performance. Number 1 crushes the competition

Best CMS CWV Performance

HTTPArchive has published latest rankings for the top performing content management systems (CMS). We review the rankings of six popular CMS and discover that the best performing CMS outpaces their competitors by huge margins.

We continue to review data related to the United States geographic region, as before.

The global data is slightly different from the United States data, but not to a degree that it changes the ranking position of any of the CMS under review.

How Core Web Vitals CMS Rankings are Determined

The HTTPArchive uses two datasets in order to arrive at the core web vitals rankings of all content management systems.

The datasets used by HTTPArchive are:

  1. CRuX dataset
  2. Lab dataset

CRuX Dataset

The CRuX dataset comes from actual website visits by real people who have opted into anonymously allowing Core Web Vitals data to be collected from the websites they visit.

Lab Dataset

The lab dataset comes from a crawler that collects data from millions of websites. The lab data simulates mobile device and mobile connectivity to arrive at the ranking scores.

These two datasets are used to determine the core web vitals scores for all of the CMS and published for review.

#1 Core Web Vitals Champion: Duda

Duda is a Professional Website Builder platform that allows businesses to get online fast without having to think about the underlying technology.

The goal is to give customers the ability to focus on their business while Duda takes care of the technology. That’s an approach that’s shared by other companies like Wix and Squarespace.

Out of those three website builder platforms it’s Duda that continues to lead.

The last time we reviewed the HTTPArchive technology report data, Duda was leading the pack by a significant margin.

This trend continues with the latest performance data that is published, which is from February 2022.

The percentage of websites built with Duda that had good core web vitals performance was a stunning 77.3%.

Back in October 2021 the percentage of good performing websites was 69.3%.

Duda’s performance benchmark improved by 8%.

A comparison of the three website building platforms in this review stacks up like this:

Comparison of SaaS Website Builders CWV Scores

  • Duda 77.3%
  • Wix 54.0%
  • Squarespace 42.8%

Duda isn’t just leading the competition, they’re outpacing them by exceptionally wide margins.

Wix, the second place website builder competitor is trailing behind Duda by over 23 percentage points.

In a way this shouldn’t be surprising because the last time we spoke to Duda they indicated that website performance was an important goal for them.

They shared that took a data-driven approach to identifying areas of improvements then rolling out updates to customer websites so that they could enjoy better and faster performance.

A spokesperson from Duda had shared:

“Using this data driven approach we were able to identify opportunities for improvements.

We implemented those improvements and checked the improvement again using our BI tool.

This was a successful iterative approach that helped us to increase scores over time.”

#2 Core Web Vitals Champion: Drupal

The second place CWV champion is the open source CMS Drupal, overtaking the second spot which was previously held by Wix.

In the past survey the percentage of Drupal sites with a good core web vitals score was 50.2%.

This year Drupal races past Wix with a score of 58.2%, with Wix trailing behind by four percentage points, with a score of 54.0%.

#3 Core Web Vitals Champion: Wix

This time around, rather than improve performance, the percentage of sites with a passing core web vitals actually fell.

This contributed to Wix dropping from position #2 to trailing behind Wix at position #3.

In the last survey Wix performance was at 55.3% of sites built with Wix enjoying a passing core web vitals score.

This year Wix performance actually dropped to 54.0%.

#4 Core Web Vitals Champion: Squarespace

Squarespace is leaping ahead with a strong improvement to the performance of its platform.

In the previous survey, Squarespace was ranked at 31.45% of sites passing CWV. This time 42.84% of Squarespace sites have a passing CWV score.

#5 Core Web Vitals Champion: WordPress

WordPress is holding on to the #5 spot, which is the same position it was ranked in back in October.

WordPress performance increased from 31% to a whopping 37.4%.

That’s a significant amount of improvement that may reflect the fine work of the WordPress performance team that is working within WordPress to improve how fast WordPress performs.

The WordPress performance team recently released an experimental performance plugin as part of their effort to try out performance improvements before they make it into the main WordPress core.

The next versions of WordPress may see more improvements.

#6 Core Web Vitals Champion: Joomla

Joomla didn’t make it into the rankings last time we surveyed the HTTPArchive results.

According to the HTTPArchive Joomla had a score of 30.5% back in September 2021, which is the date of the results reported in October.

This time around Joomla jumps right up behind WordPress with a score of 35%, a mere two percentage points behind WordPress.

These are the top ranked CMS by measured Core Web Vitals performance:

Duda’s score of 77.3% is more than twice as good than fifth place WordPress, which is currently the most popular CMS in the world.

Clearly, if web performance is important to a business, there are other CMS beyond WordPress to choose from.

But don’t count WordPress out yet because their performance team is fast catching up.
