Review and UGC apps
Review widgets, star ratings, photo reviews and testimonial blocks often inject scripts, markup containers and third-party asset URLs. This makes them one of the easiest app families to detect on a storefront.
Upsell, popup and conversion apps
Upsell drawers, urgency widgets, announcement bars and email capture popups typically expose frontend code. These apps often render visible DOM elements or load assets from identifiable vendor domains.
Analytics and tracking tools
Analytics layers are among the most consistently detectable technologies because they rely on public script loading, tracking pixels and browser-side events.
Payment methods and wallets
Wallet buttons and checkout-related payment integrations may surface public scripts or storefront elements that a detector can group separately from general merchant apps.
What is harder to detect
Apps focused on order routing, admin workflow automation, supplier sync or back-office tasks may never touch the public storefront. Those apps are functionally important but often invisible to any public detector.
Test common app patterns live
Run the Shopify App Detector on a live store to see whether review apps, popups, analytics tools or payment methods leave visible evidence.
