Amazon's product pages show the current price only, not whether it is actually a good deal compared to history. Keepa fills that gap directly on the page, showing months of price movement so shoppers and sellers can judge whether a listed price or a claimed discount is genuine.
See a product's price history at a glance
Keepa adds a chart under the buy box on Amazon product pages showing how the price has moved over time, which reveals whether a current "deal" is actually lower than recent prices or just back to normal. This helps shoppers avoid buying during a temporary price bump disguised as a discount.
Get alerted when a price drops
You can set a target price on any product and Keepa will track it, useful for big-ticket items you are willing to wait on. This suits shoppers timing a purchase around sales events and sellers monitoring competitor pricing on similar products.
What Amazon sellers use extensions for
Sellers use price history data to judge how competitors price similar products and how demand shifts around seasonal events. Keepa's data is public and price-focused; it does not show private seller metrics such as margins, inventory levels or supplier costs, which still require Amazon's own Seller Central tools.
