Limits of the measurement
- Only apps visible on the home page are counted. An app that works in the admin (invoices, packing slips, product import, inventory) leaves no trace on the storefront and does not appear here.
- An uninstalled app can still be detected if it left code in the theme.
- The sample is worldwide and limited to sites with enough traffic to appear in Chrome’s data. Shares are reliable. Absolute numbers understate the real installed base.
- Each domain counts as one store. A merchant running three stores on three domains counts three times.
Method
BigQuery query on the httparchive.crawl.pages table, crawl of August 1, 2026, mobile, home pages only. A store counts as Shopify when HTTP Archive’s Wappalyzer detection finds Shopify on it. Apps are those the same detection identifies on those pages.
