Shopify Theme Detector

Looking for a practical way to analyze Shopify store themes inside DevTools? Shopify Theme Detector is a DevTools extension that analyzes Shopify stores using client-side browser metrics. It detects whether a site is built on Shopify and provides insights such as load time, HTML size, DOM node count, DOM depth, and repeated sections to help evaluate theme structure and complexity.
