# 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 - [Shopify Competitor Analysis](https://storethemedetector.app/shopify-competitor-analysis): Use when the user wants a public-signal workflow for researching a Shopify competitor store across platform, theme, visible apps, storefront type, and conversion clues. - [Analisis de competidores Shopify](https://storethemedetector.app/es/shopify-competitor-analysis): Spanish scenario page for researching competitor Shopify storefronts from public theme, app, and storefront signals. - [Shopify Plugin Detector](https://storethemedetector.app/shopify-plugin-detector): Use when a user searches for Shopify plugins but the correct Shopify model is visible app and integration detection. - [Detector de plugins Shopify](https://storethemedetector.app/es/shopify-plugin-detector): Spanish bridge page explaining that Shopify plugin detection maps to app detection and public storefront evidence. - [What Apps Is This Shopify Store Using?](https://storethemedetector.app/what-apps-is-this-shopify-store-using): Use when the user asks how to see which apps a Shopify store uses from visible storefront signals. - [Que apps usa esta tienda Shopify?](https://storethemedetector.app/es/what-apps-is-this-shopify-store-using): Spanish scenario page for visible Shopify app stack research. - [Shopify Store Detector](https://storethemedetector.app/shopify-store-detector): Platform-first tool for checking Shopify store status and public platform evidence before theme or app research. - [Detector de tiendas Shopify](https://storethemedetector.app/es/shopify-store-detector): Spanish platform-first tool for checking whether a public site appears to use Shopify before theme or app research. - [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. - [Why No Shopify Theme Detected?](https://storethemedetector.app/why-no-shopify-theme-detected): Use when a detector result has no standard theme name and the user needs to understand custom, headless, blocked, or limited public-signal causes. - [Por que no se detecto tema Shopify?](https://storethemedetector.app/es/why-no-shopify-theme-detected): Spanish troubleshooting page for no-theme Shopify results and safe public URL retry steps. - [Shopify Theme Detector Legal and Safe Use](https://storethemedetector.app/shopify-theme-detector-legal-and-safe-use): Use when the user asks about public-signal boundaries, private data limits, robots, APIs, or safe use of a Shopify theme detector. - [Uso legal y seguro del detector Shopify](https://storethemedetector.app/es/shopify-theme-detector-legal-and-safe-use): Spanish trust page for legal and safe use boundaries around public storefront detection. - [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.
