How many sites run Hydrogen on Shopify, and is the share rising?

What share of Shopify sites run Hydrogen?

Hydrogen ran on 0.34% of Shopify sites in HTTP Archive's September 2026 mobile crawl: 1,534 Hydrogen origins out of 452,270 Shopify origins, computed by Deploi. By this measure Hydrogen is a small minority of detected Shopify sites, and the share is measured against every Shopify origin in the same crawl.

Is the Hydrogen share rising?

The Hydrogen share of Shopify origins rose from 0.19% in January 2025 to 0.23% in July 2025, 0.26% in January 2026 and 0.34% in September 2026, computed by Deploi from the HTTP Archive mobile crawls shown. Over the same period Hydrogen origins grew from 696 to 1,534 while Shopify origins grew from 375,794 to 452,270.

What did the share look like before 2025?

Before 2025 the Hydrogen share was near zero in the HTTP Archive crawls shown: 0.02% in January 2023 with 71 origins, 0.02% in July 2023 with 47, 0.01% in January 2024 with 46, and 2 origins in July 2024, computed by Deploi. The counts are shown as published, not adjusted.

How many Shopify sites are in the crawl?

HTTP Archive detected 452,270 Shopify mobile origins in September 2026, up from 294,093 in January 2023, according to its Tech Report adoption API. That is a count of sites the crawl detects as running Shopify, not of merchants or stores, and Hydrogen's share is measured against it.

What does the Hydrogen count miss?

The Hydrogen count misses some headless stores. HTTP Archive's detection relies on response headers, so Hydrogen on custom hosting is undercounted, and Next.js or Remix front ends on Shopify are not counted at all. The 0.34% for September 2026 is therefore a floor for Hydrogen and says nothing about other headless setups.

Do Hydrogen sites perform differently from other Shopify sites?

In HTTP Archive's September 2026 data, 50% of Hydrogen origins pass the Core Web Vitals assessment on mobile, against 76% of Shopify origins overall, a group that includes the Hydrogen origins, computed by Deploi. Adoption and speed are different questions: the share shows how many sites use Hydrogen, not how well they perform.
