## Description

A Chrome and Firefox extension. Open a Shopify store and click the icon. A side panel names the theme and its version, the apps grouped by type, and the tracking pixels. It counts 885 apps and 329 themes in its database. It also exports the store's public product catalog to CSV in Shopify's import format, up to 10,000 products. The export is built in the browser. The extension's code is on GitHub under the MIT license.

## Watch for

New, with 32 Chrome users at version 0.7.2 when checked, and its own site says so. Only the extension is open source. Each scan sends the store's address and page signals to its server, and the database there is not published. A paid tier is announced. No company or person is named, only registration in Andorra. Like every detector, it only sees apps with code on the storefront.
