Share: of the stores running the picked app, the share that also run each app. Lift: that share divided by the app's share of all Shopify stores we scan, so 3.0x means three times more likely than average. Click a row to build the list behind it.

Read straight from live storefronts
Alert scans Shopify storefronts and detects each installed app from what it loads on the live store. Every share here is a share of stores we have scanned, refreshed monthly.
Share answers "how many of this app's merchants run that one". Lift answers "is that more than you would expect", by dividing by the partner app's share of all stores.
Apps by the same developer, pairings above 25x (one vendor's shared code), partners under 1% of stores, Shopify-built apps, ad-channel apps, and backend-only apps with no storefront trace.
Questions about the data
What does the App Overlap Finder show?
Pick a Shopify app and it lists the other apps its merchants also run. For each one you see the share of the picked app's stores that run it, and the lift: how many times more likely those stores are to run it than the average Shopify store Alert scans.
Where does the data come from?
Alert's own scan of Shopify storefronts. Each store's installed apps are detected from what the app loads on the live store. The page refreshes monthly; the date at the top of the results is the snapshot.
Which apps are included?
Apps our detection measures reliably and that run on at least a few hundred stores we scan. Backend-only apps that leave no trace on the storefront, Shopify-built apps and the ad-channel apps of Meta, Google, TikTok, Pinterest, Snapchat and Microsoft are left out.
Why are there no store counts?
Shares and lifts compare like with like across the stores we scan, so they hold steady as the scan grows. Counts would only tell you how much of Shopify we had scanned that week.
Why are some pairings missing?
Apps from the same developer are left out of each other's lists, because a vendor promoting its own apps is not a shared buying choice. Pairings above 25x are dropped for the same reason, and a partner needs at least 1% of the picked app's stores.
How do I get the stores behind a pairing?
Start an Alert trial. Alert lists every store running the partner app but not yours, with the decision-maker, their full app stack, Plus status, and alerts when they install or remove an app.
Turn a pairing into a pipeline.
