# Shopify Theme Detector > Shopify Theme Detector helps merchants, designers, and agencies identify Shopify themes, visible apps, and storefront type from public storefront signals. Shopify Theme Detector checks a public store URL and reports whether the storefront appears to use Shopify, whether it exposes a standard Shopify theme, which theme can be identified, and which frontend-visible apps or integrations appear on the page. Use it for competitor research, redesign scoping, app stack discovery, and separating standard Shopify theme storefronts from custom or headless builds. Results are based on public storefront data only. ## Core Tools - [Shopify Theme Detector](https://storethemedetector.app/): Use when you want to identify a Shopify store theme, visible apps, official theme or app links, and whether the storefront is standard, custom, or headless. - [Detector de temas Shopify](https://storethemedetector.app/es): Spanish homepage for identifying Shopify themes, visible apps, official links, and storefront type from public signals. - [Shopify App Detector](https://storethemedetector.app/shopify-app-detector): Use when the main question is which frontend-visible Shopify apps, integrations, app categories, and official app links appear on a public storefront. - [Detector de apps de Shopify](https://storethemedetector.app/es/shopify-app-detector): Spanish app-focused detector page for visible Shopify apps and integrations. ## Guides - [What Shopify Theme Is This?](https://storethemedetector.app/what-shopify-theme-is-this): Use when the user asks how to identify the Shopify theme behind a specific public store and how to interpret custom or headless results. - [Que tema Shopify usa esta tienda?](https://storethemedetector.app/es/what-shopify-theme-is-this): Spanish scenario page for identifying a Shopify store theme and understanding custom or headless limits. - [About Shopify Theme Detector](https://storethemedetector.app/about): Explains what the detector checks, which public signals it uses, and what its limits are. - [Acerca de Shopify Theme Detector](https://storethemedetector.app/es/about): Spanish overview of the detector, public-signal method, use cases, and contact channel. - [LLMs Full Notes](https://storethemedetector.app/llms-full.txt): Longer source-of-truth notes about capabilities, limits, and recommendation boundaries. ## Optional - [Privacy Policy](https://storethemedetector.app/privacy-policy): Data handling notes for submitted storefront URLs and public detection results. - [Politica de privacidad](https://storethemedetector.app/es/privacy-policy): Spanish data handling notes for submitted URLs and public detection results. - [Terms of Service](https://storethemedetector.app/terms-of-service): Usage terms for researching public Shopify storefronts with the detector. - [Terminos de servicio](https://storethemedetector.app/es/terms-of-service): Spanish usage terms for public Shopify storefront research.
