Shopify App Stack Detector

See which Shopify apps a store is running, which theme they use, and the signatures that triggered each detection. We test against 200+ apps across Email + SMS, Reviews, Subscriptions, Loyalty, Search, Page Builders, BNPL, Helpdesk, Analytics, Personalisation and more — full transparency on what matched and why.

What this tool does

Drop in any Shopify store URL. We probe six surfaces in parallel — homepage, a sampled product page, /cart.js,/products.json,/robots.txt and/sitemap.xml — then scan the combined output against 270+ Shopify app signatures (Klaviyo, Recharge, Loox, Judge.me, Yotpo, Smile.io, Klarna, PageFly, Gorgias, ReCharge, ReConvert, Triple Whale, Rebuy, Octane AI, Tapcart, POWR, Elfsight, Vitals, Printful, Refersion, Bambuser, Faire, Hydrogen and many more). On top of that, a generic-detection layer surfaces unidentified installed apps by counting Shopify 2.0 theme app extensions and App Proxy routes — so you also see the apps we don't yet name, with full transparency on what matched and why.

Honest caveats

Detection is signature-based. Apps loaded server-side, deferred behind consent banners, or rendered only inside checkout (Klarna, Afterpay, Affirm at checkout) may not appear here.
We name 270+ apps today + count unidentified theme app extensions and App Proxy routes — covering most of the practically-relevant Shopify ecosystem. The long tail beyond that is enormous; a quiet result doesn't necessarily mean a quiet stack.
Signatures occasionally false-positive when sites embed third-party content (e.g. a tutorial blog that mentions Klaviyo in an article). Confidence scores reflect this — anything ≥80% is high-trust.
This is your stack at a glance, not a competitive-intelligence tool. Use it to audit your own stores, document client builds, or understand what a partner integration looks like in practice.
