Both extensions add price history to Amazon product pages so you can tell whether a discount is real. Keepa layers in more detail, such as buy box and sales rank history, while Camelcamelcamel keeps its charts and alerts simple and easy to read at a glance.
Price history charts on Amazon
Both extensions overlay a price history chart directly on the Amazon product page, showing how the price has moved over time. Keepa's charts include more data series, such as buy box price and sales rank, while Camelcamelcamel focuses on a cleaner chart showing just the listed price over time.
Setting price drop alerts
Camelcamelcamel lets you set a target price and sends an alert when the product drops to or below it. Keepa offers similar price alerts plus more configuration, such as tracking percentage drops or specific sellers, which suits people who track many products closely.
Extra data for sellers and researchers
Keepa's additional charts, including sales rank and buy box history, are useful for sellers researching how a product performs over time, not just shoppers checking a price. Camelcamelcamel stays focused on price tracking for everyday shopping rather than seller research.
