Keepa Amazon Price Tracker

Last updated: 12 October 2026

What the Keepa Amazon price tracker does

Keepa records Amazon prices over time. With the extension installed, its chart appears on the Amazon product page itself, just below the main listing. You see what the product has cost before, and its lowest price, without opening another site.

That is most useful in a sale. A big "was" price only means something if Amazon actually charged it recently, and the chart shows whether it did.

What the Keepa chart shows

• Amazon's own price: what Amazon charged when it was the seller.
• New and used offers: the cheapest prices from other sellers on Amazon.
• The Buy Box price: the offer Amazon features next to the Add to Basket button.
• Sales rank: a rough measure of how well the product sells in its category.

You can switch each line on or off, and change the time span from a day to the full history.

Keepa price alerts

Price alerts are the other half of the Keepa Amazon price tracker. Pick a target price on any product and Keepa tells you when the price falls to it. It can also alert you when an out-of-stock item becomes available again. Alerts arrive by email, browser push notification, Telegram or an RSS feed, or through the Keepa app.

Where it works

Keepa covers Amazon in 11 countries, including the UK. The browser extension is available for Chrome, Edge, Firefox and Opera.

On a phone, use the Keepa app for iPhone or its Android app. The app can scan a product's barcode in a shop and show you its Amazon price history on the spot. It also has a search box for any product's history.

Keepa or camelcamelcamel?

Both are free Amazon price trackers with price-drop alerts. The difference is in how you use them.

Keepa shows its chart on the Amazon page automatically, and it carries more data on each one, including sales rank and the Buy Box. It also has phone apps with a barcode scanner. camelcamelcamel is simpler: its chart shows the Amazon price on its own by default, and you set email alerts from its website. Its extension only shows a chart when you click its button, and it has no app.

Neither one checks for made-up brand names. The Knockoff Amazon brand filter does that job in your Amazon search results.

Keepa Pro, and who it is for

Keepa also sells a paid Pro subscription for €29 a month, or €290 a year. It adds sales rank and stock history back to 2011, estimates of units bought each month, Buy Box statistics and a product finder.

Those tools are built for people who sell on Amazon, to judge demand before they buy stock. A shopper watching the price of things to buy does not need it, because the history chart and the alerts are free.

The limits

Keepa only tracks Amazon. To see whether another UK shop is cheaper, you still need to look elsewhere.

The chart carries a lot of lines, which takes a minute to read the first time. For a quick check, start with the Amazon line and the lowest price.

Finally, the extension only adds a chart on desktop. On a phone you look the product up in the Keepa app instead of seeing the chart on Amazon.

Fake discounts and UK law

Misleading price-reduction claims are banned under UK consumer law. The Competition and Markets Authority explains the rules in its unfair commercial practices guidance. A Keepa chart is the quickest way to check a discount for yourself, because it shows the price Amazon charged before the sale.

You can start with the website, the extension or the app, and the Keepa Amazon price tracker is free on all three.
