The best Amazon price tracker, ranked by the kind of shopper you are

The best Amazon price tracker for most people is AyeWatch, because it watches Amazon and every other shop you buy from, takes its instructions as a sentence and pings your phone. If all you want is a long price chart on Amazon listings, Keepa and CamelCamelCamel are the specialists, and both are covered below.

Tech Twitter has a habit of posting deal screenshots ten minutes after the deal ends. Here is how to be the person who saw it first.

1. AyeWatch: best overall

AyeWatch is an AI monitor for web pages. You hand it a product URL and a rule such as "alert me when this monitor drops under $300 or a lightning deal appears", and it checks the page on a schedule. When something matches, you get a push notification with a short written summary of the change.

Why it ranks first:

• Not tied to one store. The same rule works on Amazon, a manufacturer's own shop or a niche hardware retailer.
• Plain English instead of thresholds. You can ask for things a price field alone cannot express, like a restock in one colour.
• Alerts where you already are. Push and the in-app feed on every plan; email, Slack, Discord and webhooks on paid plans. There is also a REST API on paid plans if you want to pipe alerts into your own scripts.
• Phone first. Apps for iOS and Android, plus the web.

Cost: a free preview with no card, then paid plans from $9 a month, billed in monitoring credits.

The catch: there is no price history graph. You learn when the price moves, not what it did last spring.

2. Keepa: best for Amazon price history

Keepa describes itself as an Amazon price tracker that provides price history charts and price drop alerts. Its browser add-on draws the chart right on the Amazon product page, can alert you when an item falls below your target or comes back in stock, tracks Lightning Deals and lets you compare prices across Amazon's regional stores. It lists support for eleven Amazon domains, including .com, .co.uk, .de, .co.jp and .in, and you do not need an account to start.

Pick it if you live on Amazon and want data before you buy.

3. CamelCamelCamel: best simple Amazon watcher

CamelCamelCamel bills itself as a free Amazon price tracker with price history, price watches and drop alerts. Its add-on, The Camelizer, puts a history chart on Amazon pages; you type the price you would pay and it emails you when the item gets there. The add-on listing names Amazon in the US, Canada, Australia and most of Europe.

Pick it if you want a quiet email and nothing else.

Side by side

How we ranked them

We weighted three things: how many stores a tool covers, how much effort a single alert takes to set up, and where the alert reaches you. AyeWatch wins on all three. The Amazon specialists win on one thing it does not do, the history chart, and that is a real reason to keep one installed alongside it.

Getting started

The quickest test is to paste one product link into AyeWatch and write the price you are waiting for. If you also want the chart, install Keepa or The Camelizer next to it; they do not conflict.
