## Description

Paste a store URL to get its theme with version, price and demo link, and the apps visible in its public code. Theme speed comes from Google's field data. Each scan is set against its dataset of 3.5M+ stores, 33,518+ apps and 9,959+ themes, by its own count. So it shows how common a theme or app is. Scans now also list each app's price and an estimate of the store's monthly app spend. There are statistics pages and a Chrome extension, in six languages.

## Watch for

Built for merchants copying a competitor's store, not for app vendors. It answers what one store runs, not which stores run an app. Some of its links are affiliate links, including a Shopify sign-up banner, which it says keeps the site free. The dataset figures are its own, and the monthly app spend is an estimate.
