Shopify App Detector

How the Shopify app detector works

Most Shopify apps that change the storefront add code to it: a script from the app's own server, a widget, or an app block from the Shopify theme editor. The detector loads the public page you enter, the same way a browser does, and checks the code for two things:

• Known signatures for about 80 apps and tags, such as the script domains used by Klaviyo, Judge.me, Recharge, Rebuy and Gorgias.
• App embed paths on Shopify's CDN (cdn.shopify.com/extensions/…). These carry each app's extension handle, so apps outside the list still show up by name.

It also reads the theme name from the store's settings. For more detail on themes, use the Shopify theme detector.

How to use it

1. Paste the store's domain or its .myshopify.com address and select Detect Apps.
2. Read the results by category: reviews, email and SMS, upsell, subscriptions, support, tracking.
3. If the homepage shows few apps, run a product page URL too. Some apps only load where they are used.

What it can't see

Apps that work only inside the Shopify admin, such as inventory, accounting or fulfilment apps, add nothing to the storefront, so no detector can find them from outside. Stores that block automated requests may return an error. A match means the code is on the page, not that the store still pays for the app: leftover code from uninstalled apps can stay in a theme.

Who it's for

Agencies scoping a new Shopify client, freelancers quoting a build or a speed audit, and brands looking at what competitors run. Before a pitch, a scan shows which email platform, review app and tracking setup the store already has, so the audit starts from what's installed.
