Shopify app detector

Most Shopify apps add scripts, widgets or theme app extensions to the storefront. The detector loads the store's public homepage and looks for two kinds of evidence:

• Known app signatures: script and asset domains of popular apps, such as Judge.me, Klaviyo, Yotpo, Gorgias, Recharge and Rebuy.
• Theme app extensions: assets served from cdn.shopify.com/extensions/…, which carry the app's handle even for apps that aren't in our list.

It covers more than 45 widely used apps and tags across reviews, email and SMS, chat, subscriptions, loyalty, upsells, page builders, search, translation, payments, analytics and ad pixels.

Detection is based on the homepage only, so be aware of its limits:

• Apps that only load on product, cart or checkout pages may not appear.
• Back-office apps (inventory, accounting, fulfilment) leave no trace on the storefront.
• Apps loaded through a tag manager after consent may be invisible until a visitor accepts cookies.

Treat the result as “apps we can prove are running on the storefront”, not as a complete list.

Open the page source (Ctrl+U or Cmd+Option+U) and search for cdn.shopify.com/extensions. Each match includes the app handle. Then search for vendor domains such as klaviyo, judge.me or yotpo. In the browser's Network tab, filter by JS to see every third-party script.

Knowing a competitor's reviews, upsell and email stack tells you how they convert. Pair it with their catalog: the Shopify scraper exports prices, variants and images to CSV, with a free 25-product preview. To see their design base, run the Shopify theme detector.
