Keepa does not work on Shopify. It does not work on Best Buy, Nike, Target, Walmart's own storefront, or any other non-Amazon retailer. Keepa is built entirely around Amazon's product catalog, and products that aren't on Amazon simply don't exist in its database.
This isn't a limitation Keepa is planning to fix. It's a deliberate architectural decision that follows from how Keepa was built. Understanding why helps you pick the right tool for where you actually shop.
Why Keepa is Amazon-only
Keepa's data model is built around a single identifier: the ASIN (Amazon Standard Identification Number). Every product in Keepa's database has an ASIN because every product in Keepa's database is an Amazon product. Keepa tracks prices by pulling from Amazon's product feeds, monitoring Amazon listing pages, and aggregating data from third-party sellers operating within Amazon's marketplace.
A hoodie on Gymshark's Shopify store has no ASIN. A graphics card listed on Best Buy's website carries Best Buy's own SKU, not an Amazon ASIN. A jacket on Patagonia's storefront exists entirely outside Amazon's catalog. For Keepa, these products simply don't exist. There is no workaround, no manual lookup, no way to paste a Shopify URL and get a price history chart.
Again: this is not a criticism of Keepa. Within Amazon, it's one of the best tools available, and we'll say so plainly later in this post. But the question "does Keepa work on Shopify" has a clean answer: no.
Specific stores Keepa cannot track
To make this concrete, here is a short list of storefronts where Keepa has no coverage:
Shopify-powered brands: Allbirds, Gymshark, SKIMS, Bombas, Patagonia, Chubbies, Brooklinen, and tens of thousands of independent DTC brands all run on Shopify. Keepa cannot track any of them.
Best Buy: One of the largest US electronics retailers has its own pricing and inventory system. Keepa doesn't index it.
Nike and Adidas: Both run their own storefronts with independent pricing, regional differences, and restock cycles. Keepa has no data on either.
Target: Target sells some products that are also available on Amazon, but Target's pricing is independent. Keepa tracks the Amazon listing price, not what Target charges on target.com.
Walmart.com: Despite being one of Amazon's main competitors, walmart.com pricing is not in Keepa's database.
Regional retailers and DTC brands: Any store outside Amazon's ecosystem, from European fashion brands to independent outdoor gear shops, is outside Keepa's scope.
This is a meaningful portion of where people actually spend money online. If any of these stores are in your regular shopping rotation, Keepa cannot help you there.
What Keepa does work on
To be precise about the scope: Keepa tracks products on Amazon.com (US) and on Amazon's regional marketplaces including Amazon.co.uk, .de, .fr, .it, .es, .co.jp, .ca, and .com.au, among a few others.
Within that scope, Keepa is excellent. It maintains years of price history per product, plots accurate charts directly on Amazon listing pages via a browser extension, tracks sales rank, monitors third-party seller prices on the same listing, and flags coupons and Subscribe-and-Save discounts. If you are a heavy Amazon shopper, Keepa earns its reputation.
The point here isn't that Keepa is bad. The point is that its excellent coverage stops at Amazon's borders.
Does the Keepa browser extension work on Shopify?
The Keepa browser extension is installed by millions of users and is one of the most popular shopping tools in Chrome's extension library. It works by detecting when you're on an Amazon product page (using the URL pattern) and injecting a price history chart below the product title.
When you visit a Shopify store, Gymshark's website for example, the Keepa extension is present in your browser but completely inactive. It has no data to display for that product and no mechanism to collect any. The extension's trigger logic is looking for Amazon URLs; on any non-Amazon site, it does nothing at all.
Some people install Keepa hoping it extends to other stores because the extension is always installed in their browser. It does not extend. The extension is only useful on Amazon.
CamelCamelCamel has the same limitation
CamelCamelCamel, the other widely used free Amazon price tracker, is also Amazon-only. It tracks Amazon product URLs and nothing else. Like Keepa, it is built on Amazon's ASIN system and has no way to represent a product that isn't in Amazon's catalog.
CamelCamelCamel's interface is simpler than Keepa's and it doesn't have a browser extension, but the constraint is identical. Both tools have been around for over a decade, both are genuinely useful for Amazon, and neither was ever designed to track prices elsewhere.
Why screenshot tools are a poor substitute
When people discover that Keepa and CamelCamelCamel don't cover non-Amazon stores, some turn to visual-diffing tools like Visualping. These services take a periodic screenshot of a page and alert you when any pixels change.
The problem is noise. A new promotional banner, a "3 left in stock" badge appearing, a cookie consent dialog shifting position, an A/B test rotating a headline image. Any of these will trigger a "change detected" alert. You end up receiving alerts for things that have nothing to do with price changes and missing the actual price change you cared about because it arrived alongside five false positives.
Visualping's paid plans start around $13 per month. That is a significant premium for a tool that doesn't specifically understand prices and generates considerable noise. Price-specific tools solve this more cleanly.
What actually works on Shopify and non-Amazon stores
To track prices on Shopify stores and other non-Amazon retailers, you need a tool that:
- Does not rely on Amazon's ASIN system.
- Extracts prices from product pages across different platforms and understands price fields (not just pixel changes).
- Sends targeted alerts when the price drops.
PricePing is built for exactly this. When you paste a Shopify product URL, PricePing's extraction pipeline checks for Shopify's public product JSON endpoint (every Shopify store exposes product data at /products/[handle].json). This gives exact numeric prices from structured data rather than scraped HTML. The result is fast and reliable: no pixel comparison, no false positives from page layout changes.
For stores not on Shopify, PricePing falls through a four-layer extraction pipeline: Shopify JSON first, then structured data (JSON-LD and schema.org Offer), then DOM heuristics, then a GPT-4o AI fallback for complex pages. This four-layer approach is why PricePing works across roughly 12,800 retailers including major chains, regional stores, and niche DTC brands.
The full breakdown of what PricePing does versus what Keepa does is in the PricePing vs Keepa comparison. The short version: Keepa wins on Amazon-specific depth (years of history, browser graph overlay, sales rank); PricePing wins on coverage beyond Amazon.
How to decide which tool to use
Here's a practical framework:
Use Keepa if: You buy almost exclusively on Amazon, you want a browser extension that overlays charts on Amazon listing pages, and you want deep Amazon price history going back years. Keepa's free tier is generous and it's the right tool for this use case.
Use PricePing if: Your shopping includes Shopify brands, Best Buy, Nike, or any non-Amazon retailer, or if you want one tool that covers everything including Amazon. PricePing's free plan covers 10 tracked products across any store.
Use both if: You're a heavy Amazon shopper who also buys from Shopify stores and other retailers. Keepa handles Amazon with more historical depth; PricePing handles everything else. They don't overlap in a way that causes problems.
