Keepa Review (2026): What It Does for eBay Dropshippers

You list products on eBay that you buy from Amazon when they sell, and you want to know whether a supplier's price will hold long enough to keep your margin. That is why most eBay sellers end up reading a keepa review. It is a popular free way to see an Amazon product's price and stock history. This review covers what it does, what it costs, how safe the extension is, and the step it leaves to you.

Quick answer: Keepa shows an Amazon product's price history and alerts you when the price drops or stock returns, which helps you judge a supplier before you list. It stops at the alert. Ecomli, a non-API Chrome extension for eBay dropshippers, then updates your eBay price and quantity with Stock Monitoring. In Ecomli's own comparison, Ecomli is our pick for that eBay side.

Ecomli makes Stock Monitoring; it is our pick for keeping eBay listings in line with Amazon and AliExpress suppliers. Ecomli does not sell Keepa. You can see how Stock Monitoring works or create your Ecomli account once you have read the comparison below.

• Keepa adds price history charts and price-drop and back-in-stock alerts to Amazon product pages on 10 Amazon domains, and you can start without an account.
• Keepa's Chrome Web Store listing shows 3.4 out of 5 from 5.2K ratings and 5,000,000 users, with no history of violations for the publisher.
• Keepa's paid subscription price is not shown on a public page, so this review does not quote one.
• Keepa never touches your eBay listing. Changing your eBay price or quantity after a supplier move is the step a seller still has to cover.

Keepa review: what the extension actually does

The extension is built for Amazon. Its Chrome Web Store listing describes it in one line: it "adds price history charts and the option to be alerted on price drops to all supported Amazon sites." The developer is Keepa GmbH, based in Kemnath, Germany, and the listing says it tracks prices on over 8 billion products.

For an eBay seller who sources from Amazon, four features matter most:

• Price history charts. An interactive chart sits on the Amazon product page itself, so you can see how far a price has moved before you pick that product as a supplier.
• Price drop and availability alerts. You set a price watch and the extension notifies you when the product falls below your target or returns to stock. The listing says Lightning Deals are tracked too.
• International price comparison. You can compare one product across Amazon locales.
• Marketplace coverage. The listing names amazon.com, .co.uk, .de, .co.jp, .fr, .ca, .it, .es, .in and .mx, so it works on Amazon USA as well as nine other Amazon sites.

The listing also says the extension reveals hidden minimum advertised prices and third-party merchant stock counts. For sourcing, the stock count is the useful part, because a product with one seller and thin stock is a weak supplier choice for a listing you plan to keep live for months.

For this keepa review, that is the whole job. The extension watches Amazon and tells you what happened there. It has no view of your eBay store, your sale price or your margin. If you research products this way, our guide to eBay product research tools shows where a price tracker fits next to tools that start from what sells on eBay.

Keepa free vs paid, and what we could not verify

The free side is clear from the store listing. You install the extension and the charts appear on Amazon product pages with no account required. Price watches and alerts are part of the same listing.

The paid side is harder to pin down. The company's site loads its subscription offer inside the app, after you open it, and in November 2026 we could not read a subscription price from any public page on its site. Rather than repeat a figure from a third-party blog, this review leaves the price out. If you are asking what Keepa costs per month or per year, open keepa.com, check the subscription page there, and note the date you saw it.

What Keepa does publish is how its data API is sold. Its site says every API plan includes every endpoint and marketplace, plans differ in request rate, and they are "billed monthly, cancel any time." The API is for developers and larger sellers who pull Keepa data into their own tools. A small eBay store rarely needs it.

The useful question for an eBay seller is what you pay for each tool and what each one covers. Ecomli includes unlimited active listings on every plan, so a store with 20,000 or 100,000 listings pays nothing extra for them: its $29, $99 or $199 plan is set by how many new products it imports each month, never by the listings it already has. Starter includes 1,000 monthly product imports, Pro 5,000 and Scale 10,000, all billed monthly in USD.

A Keepa subscription covers Amazon price data. Ecomli's covers listing creation and the eBay-side updates. They are different purchases, which is why the table further down compares jobs, not price tags. Full plan details are on the Ecomli pricing page.

Is the Keepa extension safe to install?

Nobody outside the developer can promise how an extension behaves, but the Chrome Web Store listing gives you the signals to check yourself. Here is what it showed when we read it this month:

• The listing says the publisher "has a good record with no history of violations" and that the extension "follows recommended practices for Chrome extensions."
• Version 5.79 was listed, with an update date of November 14, 2026, so the extension is maintained.
• The developer has identified itself as a trader under the European Union definition and lists a postal address, support email and phone number.
• The privacy section says Keepa handles personally identifiable information and declares that your data is not sold to third parties outside the approved use cases.
• The permissions cover keepa.com and Amazon domains, cookies (used to read merchant stock counts), local storage for settings and an optional context menu that is off by default.

One detail is easy to miss. The listing states that when you click an eBay link in the Keepa Box, the click is routed through the eBay affiliate program. That changes nothing in your account, but it is worth knowing if you use the extension to look up eBay prices.

The rating tells a mixed story: 3.4 out of 5 from 5.2K ratings, across 5,000,000 users. Read a page of recent reviews on the store listing before you subscribe.

Where Keepa stops for an eBay seller

A Keepa alert tells you a supplier price moved. Your eBay listing does not move with it. Between the alert and the fix there is a manual step, and on a store with a few hundred listings that step is where margins go.

Take a simple example. You list a kitchen gadget on eBay at $34.95 and buy it from Amazon at $20.00 when it sells. The Amazon price rises to $23.00.

The extension can alert you, but until you edit the eBay listing, every sale earns $3.00 less before eBay's fees. The eBay selling fees page lists the final value fee for each category, and that fee is charged on the full sale, so a supplier increase cuts straight into what you keep. Our eBay dropshipping profit margin guide walks through the full calculation.

Stock is the second gap. When an Amazon supplier sells out, the extension can tell you it is back later, but the eBay listing stays live in the meantime unless you set the quantity to zero or end it. eBay's own out-of-stock control keeps a zero-quantity listing alive until you restock, and that setting works best when something sets the quantity for you.

Ecomli covers this step. Stock Monitoring checks the Amazon or AliExpress supplier behind each of your Ecomli listings, then updates the eBay price with your markup and the quantity, or ends out-of-stock items, using the rules you set.

If Ecomli cannot read a supplier page, the listing is held unchanged instead of being ended, so a failed read does not take a good listing down. Checks run in your desktop Chrome browser while it is open; Ecomli does not promise a check interval. If you want to compare rule-based tools, our guide to configuring an eBay repricer explains what a price rule should follow.

Keepa vs Ecomli for supplier price watching

Here is how the two compare on the jobs an eBay seller cares about, as of Nov 2026. Ecomli includes unlimited active listings on every plan, and its plans are priced by monthly product imports. Where a Keepa detail was not on a page we could open, the cell says "not established."

Keepa is the better fit for one narrow job: checking an Amazon product's price history before you decide to list it. Ecomli is the better fit for everything after that decision, because it is the tool that changes your eBay listing.

Who Ecomli is for

Sellers who list products on eBay and source them from Amazon or AliExpress, and who want supplier price and stock changes reflected on eBay without editing each listing. It suits stores that are growing, since active listings never raise the plan price.

Who Ecomli is not for

Sellers who only want Amazon price history for their own shopping, sellers who sell on Amazon, and resellers who own their stock and never buy from an online supplier. Ecomli sells on eBay only and sources products from Amazon and AliExpress, so Keepa on its own is enough for those readers.

Our verdict

The short version of this keepa review: Keepa earns its place as a research aid. Its charts are the quickest way to see whether an Amazon supplier price swings, and the free version does that well. For running an eBay store, Ecomli is our pick, because a price chart does not keep your listing profitable. If you are looking for a Keepa alternative, our roundup of other Amazon price trackers for eBay sellers compares the options side by side.

How to do this in Ecomli

You can keep Keepa for research and let Ecomli handle the eBay side. The routine looks like this:

1. Research the product. Use Keepa's chart to check how stable the Amazon price has been, or use Ecomli's Product Hunting to start from products that already sell on eBay and match them to Amazon or AliExpress.
2. Create the listing in Ecomli. Create Listings reads the supplier product, prices it with your markup, writes an optional AI title and description from the supplier facts, and runs Safety Shield and duplicate checks before publishing to eBay from your signed-in browser.
3. Set your Stock Monitoring rules. Choose your markup, your out-of-stock rule (set quantity to 0 or end the listing), the quantity to restore when stock returns, and a price-change tolerance so small supplier moves are ignored.
4. Run Stock Monitoring. Ecomli checks each supplier's stock and price, updates the eBay price and quantity or ends out-of-stock items, and shows the results, including any supplier it could not read.
5. Review the results. Check listings that were held because a supplier page could not be read, and fix the supplier link if it has changed.

Listings you already have on eBay can come into Ecomli through Migration from an eBay CSV export, AutoDS or EcomSniper, so they can be monitored the same way. Listings without an Amazon or AliExpress supplier stay on eBay but are not monitored.

Keepa review FAQ

What is the Keepa app used for?

Keepa is used to see an Amazon product's price history and to get alerts when a price drops or an item returns to stock. Shoppers use it to judge whether a sale is real. eBay sellers who source from Amazon use it to check how stable a supplier price is before they list.

How does Keepa compare with CamelCamelCamel?

Both are Amazon price-history trackers with charts and price alerts. Keepa puts its chart directly on the Amazon product page through its extension, and its listing names stock alerts and international price comparison among its features. Our Keepa alternatives guide covers CamelCamelCamel and other trackers in more detail.

What does Keepa cost per month?

Keepa shows its subscription price inside its site rather than on a public page, and we could not read it in November 2026. Check keepa.com for the current monthly and yearly price. Its data API plans are billed monthly and differ by request rate.

Is Keepa free or paid?

Both. The extension is free to install, and price history charts work with no account. Keepa also sells a paid subscription and separate API plans for heavier data use.

Is Keepa trustworthy?

Its Chrome Web Store listing says the publisher has a good record with no history of violations, the extension follows recommended practices, and user data is not sold to third parties outside approved uses. It holds 3.4 out of 5 from 5.2K ratings. Read recent reviews before paying.

Does Keepa work on Amazon USA?

Yes. The listing names amazon.com first among the 10 Amazon domains it supports, along with the UK, Germany, Japan, France, Canada, Italy, Spain, India and Mexico sites.

Is this the Keepa magnetic clip review?

No. Keepa's site and its Chrome Web Store listing describe only the Amazon price tracker and its data services. A search for a Keepa magnetic clip review is looking for a different product, which this keepa review does not cover.
