Store detectors

Store detectors

App and theme detector with a wide free tool set.

Watch for. Monetized through affiliate links and a Shopify referral offer, so the surrounding recommendations are not neutral.

Alternatives to ShopScan

Free, API paid

Store detectors

Extension-first store analysis, 7,548 apps and tools.

Watch for. Small and new, version 1.0.0 at time of checking. Like every detector, it only sees apps with a storefront presence.

Alternatives to WeLookup

Free

Store detectors

Paste a store URL and get its storefront apps, free and without an account.

Watch for. One store at a time and two pages deep. So it answers what a store runs, never which stores run your competitor. A run on allbirds.com returned five apps. No list of detectable apps is published. It exists to sell the Copyfy subscription to dropshippers. The 29,870+ sellers and 4.8 rating on the page are its own figures.

Alternatives to Copyfy Apps Detector

Free, no sign-up

Store detectors

A free theme and app detector for one store at a time, with usage counts across its scans.

Watch for. Built for merchants copying a competitor's store, not for app developers. It answers what one store runs, not which stores run an app. Some of its links are affiliate links, including a Shopify sign-up banner, which it says keeps the site free. The dataset figures are its own, and the monthly app spend is an estimate.

Store detectors

Chrome extension reading a store's apps, theme and estimated numbers.

Watch for. Monetized by affiliate links, to TikTok, Klaviyo, Zendrop, Printify and NordVPN among others. It also has an affiliate and an ambassador program of its own. So nothing it recommends around the data is neutral. No legal entity, country or person is named anywhere on the site. The sales and traffic figures are estimates published with no method attached. Use them to rank stores, not to quote one.

Store detectors

An ad and store research tool for ecommerce brands, with a free Shopify app detector.

Watch for. It is made for merchants who study what other stores sell, not for app developers. Its store filters are traffic, growth, creation date and theme. Nothing on the site says you can list the stores that run a given app, which is the search an app developer would pay for. Starter allows 5 store lookups a week. The operator is HVSCALE SERVICES FZCO, a Dubai free zone company named only in the terms of service. The 100,000+ users and 1 million stores are its own figures.

Store detectors

Free browser extension naming a store's theme, apps and trackers, with a catalog export.

Watch for. New, with 32 Chrome users at version 0.7.2 when checked, and its own site says so. Only the extension is open source. Each scan sends the store's address and page signals to its server, and the database there is not published. A paid tier is announced. No company or person is named, only registration in Andorra. Like every detector, it only sees apps with code on the storefront.

Alternatives to Stackpeek

Free, no account

Store detectors

Chrome extension listing a store's apps, theme and products.

Watch for. Built by ReConvert Ltd, which sells a post-purchase upsell app to Shopify merchants, now as Upsell.com. The listing says it "may get affiliate commission from installs initiated by the extension", so the apps it points you to can be paid placements. Its Chrome privacy disclosure lists personal, financial, authentication and communication data, with no reason given. No count of detectable apps is published. Like every detector, it only sees apps with code on the storefront.

Alternatives to Shoper Spy

Free to install, no paid plan statedby ReConvert Ltd

Store detectors

Chrome extension for store analysis: products, live sales, apps and theme.

Watch for. App detection is one feature of five, and no list of detectable apps is published. It is built for copying: the export and the review download are meant for importing a competitor's products and reviews into your own store. Same owner as SellerCenter, listed here, which has its own free app detector. The only contact is a Gmail address. Last updated April 2026.

Alternatives to Shopify Raise

Store detectors

Dropshipper spy tool, with a store explorer and an API behind it.

Watch for. It is not built for you, and it is listed for one part of it. Its own homepage says join 130,000+ merchants. The product, the price and the whole library around it are aimed at dropshippers choosing products. So the store explorer comes attached to something else and is priced with it. The order figures are AI predictions, not measured sales, and its own copy says so plainly. So they rank stores and do not report revenue. It names no company, entity or country anywhere on the site. It states that it issues no refunds.

Alternatives to PPSPY

Free plan, then $39 / $99 / $299 a month

Store detectors

Website technology stack analysis tool with technographic insights.

Watch for. The tool lacks independent customer reviews, making it hard to gauge user satisfaction. There's no transparency about the actual number of customers or companies using the service. Although a founding year is provided, other establishment details like funding or team size are absent. Pricing, while published, might not encompass all potential costs for Enterprise services since details require a sales conversation.

also in this category. Listed under App Store ASO

Category rankings and collections, with a free plan.

Watch for. Owned by OmegaTheme, which runs a large portfolio of Shopify apps. So the same conflict applies as with any tracker built by an app developer. Developer analytics sit behind a login, and the depth is unproven.

Alternatives to LetsMetrix

also in this category. Listed under Store databases

Lists of websites by the technology they run, Shopify stores included, from $29 a list.

Watch for. Built for any technology, not for Shopify apps. Its Shopify apps category lists 155 apps, a small part of the App Store, so most competitors you look up will not be detected. Its own Store Leads comparison says to stay on Store Leads for app and install depth. It is one founder's company in Mumbai, under Indian law. Its terms forbid using the data beyond your own business without a separate licence.

Alternatives to TechLeads

Free, then from $249/moby Mehboob Shaikhnot Shopify-only

also in this category. Listed under Store databases

Dropshipper research platform with a 2.4M-store Shopify database and a free app detector.

Watch for. It is not shown to answer the question this category exists for: which stores run my competitor. The app filter is a checkbox for whether a store has apps installed, not a choice of which app. The detector reads one store at a time, with no published method or app list. Every search shows at most 300 results on the free and Basic plans, and 1,000 on Expert. Free accounts cannot export. Sales and traffic are estimates with no method attached. It is built and priced for dropshippers. Refunds are limited to the first purchase within 24 hours.
