Change in data population

  • The total number of Shopify websites increased by 0.02% to 604,372 on mobile devices. On desktop devices, it increased by 0.02% to 301,144.
  • New themes added this month: Zenith, Force, Poco, Filo.
  • Themes dropped due to not enough data: Mosaic.
  • I now show 343 (up from 340) total themes. 235 have performance data for mobile devices and 202 for desktop devices.

Shopify overall performance changes

Here are the median, min, and max performance numbers on mobile for all the Shopify themes measured on mobile devices:

Websites passing All Core Web Vitals increased by 0.90 percentage points to 85.30% on mobile. On desktop devices, it increased by 0.50 percentage points to 85.60%.

For Largest Contentful Paint (LCP), mobile improved by 0.65 points and desktop stayed the same. For CLS, mobile devices decreased by 0.05 points while desktop finally improved some by 1.05 points. For INP, mobile improved by 0.2 points and desktop improved by 0.1 points bring it back up to 100%.

Number of themes with improved (and worsened) performance

This month, about 2/3 of the themes improved in performance on both mobile and desktop.

Update on new flagship Shopify theme Horizon

Horizon is still struggling with performance, but seems to be on a upward path.

As you may recall last month, Mateusz Krzeszowiak discovered a bug in Chrome that might explain a large portion of the performance issues. Chrome version 145 contained a fix that was released on 10 February 2026.

Desktop performance improved a bit by 1.1 points to 90.6% of sites having good performance. Mobile improved by 3.3 points to 72%. It's definitely an improvement albeit a bit slow.

A little less than 2/3 of the month had a fix, but rollout can take time across user devices.

The Shopify published data does not look as poor which could be due to:

  • Their data only shows the last 3 version releases, not all versions live on websites.
  • Our data includes only websites covered in the Chrome User Experience Report, about 600K, while theirs includes all sites using a custom domain (not using myshopify.com).
  • Similarly, our data only reports Chrome on Chromium. On mobile devices, this means mostly Android. The biggest difference is that their data includes iPhones which is a large chunk of US and Canadian shoppers.
  • Their data combines mobile and desktop so some of the nuance is lost in averaging.

Hopefully next month we'll see much more of a swing upward if the low performance is primarily due to the bug. As it stands, they are ranked 209th out of 235 themes on performance.

See full data on the Horizon theme page.

Most improved themes

For mobile devices, these themes had the most improvement in passing all Core Web Vitals:

  1. Lorenza: 14.0 points (55 origins)
  2. Tokyo: 10.0 points (59 origins)
  3. Infinity: 10.0 points (66 origins)
  4. Neat: 9.5 points (69 origins)
  5. Etheryx: 9.5 points (60 origins)

For desktop devices, these themes improved the most:

  1. Motto: 12.0 points (94 origins)
  2. Ultra: 8.2 points (95 origins)
  3. Aesthetic: 7.8 points (51 origins)
  4. Sitar: 6.8 points (63 origins)
  5. Boutique: 6.0 points (58 origins)

When themes on these lists have a small number of origins/market share, some of the improvements could be due to the underlying population of websites changing.

Highest market growth

As a reminder, the market share numbers calculated in Theme Vitals are not the same as number of installs. Here, we’re calculating market share based on the number of origins (websites/domains) in CrUX. CrUX only shares data for websites that reach a certain threshold of popularity. This threshold sometimes changes. To learn more, check out the methodology page for CrUX.

Growth in number of origins

The themes that already have the largest market shares usually have the highest growth in number of origins.

Mobile

  1. Horizon: 2192
  2. Dawn: 1497
  3. Tinker: 256
  4. Savor: 230
  5. Atelier: 211

Desktop

  1. Horizon: 645
  2. Dawn: 508
  3. Impact: 110
  4. Hyper: 109
  5. Tinker: 100

Percent growth in origins

Raw growth is interesting but usually focuses too much on the existing themes with high market share. Here, I show which themes are growing the fastest on a percentage basis.

Mobile

  1. Maximize: 34.7%
  2. Purity: 24.2%
  3. Horizon: 21.5%
  4. Etheryx: 20.0%
  5. Tinker: 19.3%

Desktop

  1. Purity: 25.0%
  2. Flawless: 23.2%
  3. Nordic: 22.2%
  4. Tinker: 21.4%
  5. Horizon: 20.4%
