Keepa Amazon price tracker: a setup guide, and when to add a second tool
How to set up Keepa's charts and price watches, how it compares with camelcamelcamel, and why AyeWatch covers the pages Amazon trackers cannot see.

Keepa is an Amazon price tracker that draws price history charts onto Amazon product pages and alerts you when an item falls below your target price or comes back in stock. You can have the Keepa Amazon price tracker running in a few minutes from the browser add-on or the iPhone app; for the product pages it cannot see, add AyeWatch, which watches any public store page and can hand its alert to a webhook.
What Keepa covers
Keepa's Firefox add-on listing, published by Keepa.com and updated in late October 2026, lists these features:
- Interactive price history charts on the Amazon product page itself
- Price watches that fire on a drop below your target or a return to stock, including Lightning Deals
- Price comparison across Amazon locales
- Hover previews of the history when you point at a product link
- Eleven marketplaces: .com, .co.uk, .de, .fr, .co.jp, .ca, .it, .es, .in, .com.mx and .com.br
You do not need an account to start. The iPhone app, from Keepa GmbH and free to download, adds sales rank, Buy Box history and offer counts, plus a barcode scanner for checking online prices while you stand in a shop.
Set it up in four steps
- Install it. Add the extension to your browser, or the app to your phone. The Firefox build needs Firefox 140 or later.
- Open an Amazon product. The chart appears on the page, so you can see how the price has moved before you decide.
- Create a price watch. Enter the price you would pay, or ask to be told when the item is back in stock.
- Check the alert before you buy. Prices move, so confirm on the product page when the notice arrives.
For developers, one detail on the Firefox listing is worth reading: the add-on only runs on keepa.com and the Amazon domains it supports, and it sends the product's ASIN to Keepa to draw the chart.
Keepa or camelcamelcamel
Both are Amazon trackers with history and alerts. The difference is depth.
| Keepa | camelcamelcamel | |
|---|---|---|
| Amazon stores | 11 marketplaces | US, Canada, Europe, Australia |
| History | Price, plus sales rank and Buy Box in the app | Price history |
| Alerts | Price drop or back in stock | Email when a watched price drops |
| Where | Extension and iPhone app | Website and The Camelizer extension |
If you only want to know whether a deal is real, camelcamelcamel is enough. If you sell on Amazon or study a listing's competition, Keepa's extra data is the reason to use it.
Where an Amazon tracker stops
Keepa and camelcamelcamel both end at Amazon's borders. The keyboard you want might be cheaper on the maker's own shop, the GPU might restock at another retailer first, and the SaaS tool you pay for might change its pricing page. None of that shows up in an Amazon chart.
Add AyeWatch for every other page
AyeWatch watches a web page you paste and alerts you when it changes in the way you described in plain English, such as "tell me if this drops under $120 or the 75% layout is back in stock". It replies with a short summary instead of a raw diff.
The part developers tend to like is where the alert goes. Push and the in-app feed are on every plan. Paid plans, from $9 a month as of November 2026, add email, Slack, Discord, webhooks and a REST API, so a price alert can land in a channel or trigger a script you already run. There is a Free Preview with no card if you want to try one page first.
AyeWatch has no price history chart and no Amazon sales data, so it does not replace Keepa. Run Keepa for Amazon, and AyeWatch for everything Keepa cannot reach.
