Keepa

Keepa is a comprehensive Amazon price tracking and product research tool designed to give users full visibility into historical and real-time pricing data. It aggregates detailed price history charts for millions of products across multiple Amazon marketplaces, helping users understand long-term trends rather than relying on current prices alone. Its primary purpose is to support more informed purchasing, repricing, and inventory decisions for both consumers and sellers.

Key features include granular price history charts that track Amazon, third-party new, used, and marketplace prices over time, along with sales rank history. Keepa offers price drop alerts and customizable price watches, notifying users via email, browser, or other channels when products reach target price thresholds. A browser extension overlays data directly on Amazon product pages, adding historical graphs, price statistics, and deal indicators without leaving the site. Additional capabilities include daily drop lists, product tracking across regions, and access to a powerful API for developers and advanced users.
