Shopify App Stack Detector
Paste any Shopify store URL - we'll detect which apps it has installed across 18+ categories. Public data, fingerprint-based, no scraping behind login.
What this tool does
See exactly which Shopify apps any storefront has installed
This tool fingerprints any Shopify storefront against a database of 50+ known Shopify apps across 18 categories - reviews, email, loyalty, subscriptions, search, page builders, live chat, mobile apps, and more. We scan the home page and one product page, look for known signatures (script URLs, CSS classes, window globals), and return a categorized list with confidence ratings. Public data only, no login required.
How to use it
Detect any Shopify store's app stack
- 1
Paste the storefront URL (yours or a competitor's). Custom domain or .myshopify.com both work.
- 2
Click Detect apps. The tool fetches the home page and one product page and runs them through our fingerprint database in 3-5 seconds.
- 3
Read the categorized results. Apps are grouped by category (Reviews, Email/SMS, Loyalty, etc.) and rated by confidence: high (multiple strong signals), medium (single strong signal), low (weak hints only).
- 4
Click any app's link to visit its marketplace page if you want to evaluate it for your own store.
Merchant tips
How merchants actually use this
Competitive research: map your top 5 category competitors' app stacks. Patterns emerge fast - common apps often correlate with category-leading retention or conversion.
App vetting: before paying for a $40-200/mo app, see how many real, established Shopify stores actually run it. Empty market share = either niche or abandoned.
Migration planning: when a brand moves to Shopify, app-stack visibility on their old + new storefronts shows what they're keeping vs replacing.
Agency proposals: confirm a prospect's current stack before scoping integration work. Don't quote a Klaviyo migration if they already moved to Postscript.
