We looked at every app, pixel and payment tool on 589,683 Shopify storefronts, every store in our catalog that the HTTP Archive crawled in September 2026. The typical store runs 6 apps, and the software a store adds as it grows says a lot about its size.
Shopify stores we estimate under $100K a year run an average of 5.6 apps; stores estimated at $10M+ a year run 11.8 — 2.1× as many.
The count rises with every revenue band we measured. More revenue, more software: a store's app count is one of the clearest size tells on its storefront.

Google Analytics is the most common install, on 72.9% of stores, followed by Meta Pixel (64.4%) and PayPal (54.5%). Measurement and advertising are table stakes.
Klaviyo runs on 24.3% of all stores — and on 62.8% of stores that run any email platform.
The chart shows the top 20 apps as shares of all 589,683 storefronts.
Among stores that run any software in a category, this is the share running its most common app.
Comparing stores estimated at $10M+ a year with $1M–$10M stores, the biggest gap is in A/B testing (17.7% vs 11.7%, 1.5×).
Adoption of SMS marketing (8.2% vs 7.2%), email marketing (62.2% vs 63.6%) and product reviews (62.9% vs 65.3%) is about the same in both groups: stores take them on early, whatever their size.
Some run the other way: subscriptions (3.8% vs 6.2%) is more common among $1M–$10M stores than among $10M+ ones.
Share of $10M+ stores running each app, against its share across all stores. When you see these, you're more likely looking at a scaled brand:
Apps shown run on at least 590 stores, 11 of them $10M+.
64.3% of storefronts run both an analytics tool and an advertising pixel — 379,178 of 589,683 stores.
Across five core categories (ads, analytics, email, payments and reviews) the most common full combination is Ads + Analytics + Email + Payments + Reviews, on 14.7% of stores.
United States accounts for 41.1% of stores with a known country.

Every live Shopify storefront in Undercart's catalog that the HTTP Archive crawled (September 2026 crawl): 589,683 stores, 576,105 of them with at least one detected app. Stores flagged as non-stores, deleted, or redirecting to another store are excluded.
From the HTTP Archive's crawl of each store's homepage: the technologies it identifies and the third-party requests the page makes, matched to Undercart's app catalog. Every store is measured the same way. Apps that leave no trace on a homepage are undercounted, so shares are a floor.
Each store's band is Undercart's preliminary revenue estimate from its traffic rank (Tranco and the Chrome UX Report), the same method for every store. It places stores in bands, not exact figures: under $100K, $100K–$1M, $1M–$10M and $10M+ a year.
Recomputed every quarter from the latest crawl. This version was computed on October 15, 2026. The first edition (July 2026) covered 1,041 stores Undercart had fully profiled; this one covers the whole catalog, so its shares are not comparable with that edition's.
Undercart maintains an index of Shopify merchants — revenue estimates, full tech stacks, ad signals and social reach. The numbers in this report come straight out of it. If you want this depth on a specific store, a competitor set or the whole market, that's the product.
