Shopify Theme Detector & Apps — Stackpeek

Instantly see any Shopify store's theme, apps and trackers. Export to CSV. Fast, minimal-permission, never records your browsing.

Research any Shopify store without the manual detective work. In one click, Stackpeek turns the storefront you are viewing into a practical research brief: its theme, apps, trackers, infrastructure, public product catalogue and current best sellers — in about a second, without leaving the tab. Use it to compare competitors, shortlist tools, scope a client or prospect store, and plan your next build with less guesswork. No account. No sign-up. No email required. Free. 🔎 Research a store without the busywork - Compare the themes and apps behind stores you admire before choosing your own - Audit a merchant, client or prospect store without assembling the stack by hand - Understand how a store handles reviews, email, subscriptions, loyalty, search, payments and advertising - Compare catalogue size, pricing, variants and current best sellers - Take public product data into a spreadsheet or a Shopify import workflow 🧩 What you can learn Theme. Identify catalogue themes by name, version, creator and price, including paid themes. See whether a store uses the original theme, a customized fork or a bespoke build. As a Shopify theme checker, Stackpeek helps you trace the starting point behind a design instead of mistaking every modification for a completely custom theme. Apps. See the apps Stackpeek can fingerprint, grouped by purpose: page builders, email, reviews, upsell, subscriptions, loyalty, shipping and more. Use the Shopify app detector to compare how other stores solve a problem, build a shortlist for your own store, or review the tools already present in a client build. Trackers and infrastructure. See which advertising and analytics pixels a storefront loads, each one named in the panel rather than counted as a total. CDN, payment, consent and search services appear alongside the app stack, giving you a clearer picture of the systems supporting the storefront. Products. Review catalogue size, price range, variant count and the store's current best sellers from the same public sources any visitor can open. Use the overview to compare assortments, examine pricing and decide where deeper research is worthwhile. 📦 Export public products to Shopify-ready CSV Export products from a Shopify store to CSV in Shopify's own product-import format. Stackpeek includes every public product and variant, for the first 10,000 products, with titles, descriptions, prices, compare-at prices, SKUs, weights, options, tags and image URLs. Open the file in a spreadsheet for analysis or use it in a Shopify import workflow without rebuilding the catalogue row by row. The public feed does not expose everything. Stock levels and barcodes are left empty rather than invented. SEO titles and descriptions are filled only for storefronts read through Shopify's Storefront API, and only where the merchant published them; the public product feed most stores expose carries no SEO fields at all. Exports cover the first 10,000 products. The catalogue is assembled in your browser and is never sent to Stackpeek. 🎯 Evidence without false certainty Detection is not always absolute, so Stackpeek shows you where judgment is needed. Weaker app matches are marked "unverified" instead of being silently discarded. Unknown app hosts and trackers are counted, so gaps stay visible. A modified catalogue theme is marked "customized". A bespoke build is labelled "custom". A headless storefront is labelled "headless", because its theme cannot be detected from the page. A site that is not Shopify is reported as not Shopify. You see what Stackpeek knows, what it suspects and what it cannot tell. 🔓 Open source — read it before you install it Stackpeek asks to read the page you are looking at, so the extension's own source code is published in full under the MIT licence: https://github.com/tonic20/stackpeek-extension Everything below can be checked there rather than taken on trust: what is read from the page, what is sent, what is not, and the permission list itself. Every release is published with its tests and build passing. 🔒 Private by design Stackpeek runs only on the page you choose, when you click its icon. It asks for four permissions: - activeTab — read the page you are on after you click the icon - scripting — run the detector on that page - sidePanel — show the results beside the store - storage — remember one anonymous install ID Your browsing history is not collected. Telling a Shopify store from any other page means reading the page's technical signals and sending them for matching. If it is not a Shopify store, nothing about the page itself is stored — no URL, no domain, no record of the store. An anonymous counter of how many scans this install has run still ticks, and it knows nothing about what was scanned. When you run a scan, the store's URL (without query strings) and public technical signals are sent to our server for matching and to improve the fingerprint catalogue. The record is attached to the store, not to the install that reported it, so it cannot become a history of stores you viewed. Open any Shopify store, click Stackpeek, and turn what you find into your next decision.
