Shopify Theme Detector & Apps - Stackpeek

Use this Shopify theme detector to see any store's theme, apps and trackers: an app detector and pixel checker with CSV export.

🔍 Stackpeek is a Shopify theme detector extension and app detector in your side panel. Open a shop, click the icon, and in about a second you see what it is built on: theme, apps, tracking pixels, catalogue and top sellers, without leaving the tab. 🚀 Quick start 1️⃣ Open any online shop you are curious about. 2️⃣ Click the Stackpeek icon in the toolbar. 3️⃣ Read the answer in the panel beside the page. 🧭 Why this extension ➤ One click instead of digging through page source to see which apps run and what the site tracks. ➤ A theme checker, an app detector and a pixel checker in one panel, so you stop switching between tabs. ➤ Alt+Shift+S opens it from the keyboard. No account, no sign-up, no email. 🧩 What each scan shows - Theme: name, version, creator and price, paid ones included. It also tells the original from a customized fork, a bespoke build or a headless storefront. - Apps: every one it can fingerprint, grouped by job: page builders, email, reviews, upsell, subscriptions, loyalty, shipping and more. - Trackers: each advertising and analytics pixel, named rather than counted. - Shopify tech stack: CDN, payment, consent and search services. - Products: catalogue size, price range and variant count. - Top sellers: the shop's own top products, in order. ⚡ Auto-scan, if you want it ▸ Switch it on and the panel scans each tab you open, no click needed. ▸ A dot on the icon marks each store on the platform, checked on your device. ▸ It asks for access to all sites, so it is off until you turn it on. 📦 Export the catalogue • Every public product and variant, up to 10,000, as a CSV in the platform's own import format. • Titles, descriptions, prices, compare-at prices, SKUs, weights, options, tags and image URLs. • It does the job of a Shopify scraper, with no code to write. • The file is built in your browser and never sent to Stackpeek. • Scan results: copy them as Markdown, or save them as CSV or JSON. 🎯 Results you can check ◆ Weak app matches stay in the list, flagged as unverified next to the strong ones. ◆ Top sellers come only from the shop's own sort order, and only once it is verified. ◆ A site that is not on the platform is reported as such, never guessed. 🕵️ Who uses it 1. Merchants: the apps and pixels behind the shops you admire. 2. Agencies: a website technology checker for pitches, audits and migrations. 3. Marketers: ecommerce competitor analysis of a rival's pixels, apps and offers. 4. Dropshippers: a product research tool for catalogue size, prices and top sellers. 5. Developers: a quick competitor analysis tool before you quote the job. 🔒 Private by design ✔️ No browsing history is kept. The extension reads technical signals from the page you scan and sends them for matching. ✔️ Nothing is kept about pages that are not shops; for a store, the record attaches to it, not to you. ✔️ Four permissions: activeTab, scripting, sidePanel, and storage for one anonymous install ID. Access to all sites only if you turn on auto-scan. ✔️ Open source under the MIT license: https://github.com/tonic20/stackpeek-extension ✔️ Privacy policy: https://stackpeek.app/privacy ❓ Questions and answers 📌 What Shopify theme is this shop using? 💡 Click the icon on the page. The panel names the theme, with its version and price. 📌 What theme is this, if the merchant renamed it? 💡 The theme checker traces a renamed copy back to the original by the catalogue ID it keeps, and marks an edited one as a customized fork. 📌 Why an extension and not a website? 💡 An online Shopify theme detector fetches pages from its own server, and many shops block that. The extension reads the page you already have open. 📌 What is this website built with, if it is not a shop? 💡 Stackpeek reads one platform only, as a website theme detector for its storefronts. Other sites get a clear answer instead of a guess. 📌 Which browsers and languages? 💡 Chrome on Windows, Mac, Linux and Chromebook, plus a Firefox version. The panel speaks 15 languages. ℹ️ An independent extension, not affiliated with Shopify Inc. Product names belong to their owners. ✅ Add Stackpeek to Chrome and open the next shop you wonder about.
