## Methodology

Shoplist crawls Shopify storefronts to detect which apps each store runs, and reads each app’s Shopify App Store listing for reviews, pricing, features and integrations. Store counts for Klaviyo and Stream are as of Nov 9, 2026. “Not detectable from storefronts” means an app leaves no storefront trace, so Shoplist can’t count its stores. A row names who is ahead only when every app has a measured, unestimated figure. See [data methodology](https://shoplist.co/data-methodology.md).
