About Keepa
Keepa gives you the most detailed Amazon price history you can get in a browser. The chart on the product page tells you quickly whether a deal is real. It also has the most privacy history to worry about, so read the last paragraph before you install.
Keepa GmbH, a German company, adds a chart of new, used and warehouse prices, with alerts for a target price or a restock. Its listing says it also tracks Lightning Deals and compares prices across ten Amazon countries. It is free, needs no account to start tracking according to the listing, and works in Chrome, Firefox and Edge.
Keepa is not an affiliate coupon tool, but it does collect data. Its Chrome listing says it handles personally identifiable information and that this is not sold, and that clicks on eBay links in the Keepa Box go through the eBay affiliate program. In 2021 researcher Wladimir Palant found a persistent identifier, reporting of the Amazon pages you viewed and background loading of other Amazon pages. Later notes suggest some of that continued, and we could not confirm what has changed. If you only want a chart now and then, The Camelizer asks for much less.
