Detect tech stacks, Shopify apps, themes, and export product catalogs from independent stores. Stop guessing what your competitors run. ShopStack shows you—in seconds. ShopStack is a free Chrome extension for anyone who researches e-commerce stores: Shopify sellers, agencies, developers, and product hunters. Visit any store, click the icon, and get a clear picture of the platform, apps, theme, and marketing stack—without logging into anyone's admin panel. WHAT SHOPSTACK DOES Instant tech stack detection • Identifies Shopify, WordPress, and 800+ other technologies (payments, analytics, email, reviews, BNPL, live chat, and more) • Shows confidence for each detection so you know what's solid vs. inferred • Works on the page you're already viewing—no setup, no account Built for Shopify research • Lists third-party Shopify apps (reviews, subscriptions, shipping, loyalty, search, and more) with category filters • Surfaces theme name, version, and Theme Store links when available • Highlights payment, checkout, and analytics tools in one summary Product catalog export • Open the side panel on a Shopify store to browse public product data • Sort by price, date, or bestseller collection rank • Export to CSV or Excel—selected products, a collection, or the full catalog • Save stores and revisit scan history from your browser Reference metrics (Shopify only) • Optional revenue range estimate and store score based on public signals • Clearly labeled as reference only—not real sales data WHY INSTALL SHOPSTACK? • See which apps a competitor uses — detected Shopify apps and marketing tools on their live storefront • Audit a client's or prospect's store — platform, theme, apps, and integrations in one view • Build a product research spreadsheet — export catalog data without copy-pasting from product pages • Compare stores over time — saved favorites and scan history stay in your browser • Research without touching admin — only public HTML, scripts, headers, and JSON; never store back office If you've ever opened DevTools or searched page source for "klaviyo" to guess a competitor's stack—ShopStack replaces that with one click. PRIVACY • Local analysis on pages you actively open • No account, no subscription, no cloud sync • No access to Shopify or any platform admin • Saved stores and history stay on your device only Privacy policy: https://shopstack.lilibu.com/privacy Free.
