Keepa is an advanced Amazon price tracking tool used by frequent Amazon shoppers, resellers, and data-driven consumers around the world on web browsers and as a browser extension. It provides detailed price history charts, multi-variant price drop alerts, sales rank tracking, Buy Box history, international Amazon marketplace support, and product watchlists, all integrated directly into the Amazon product page experience. This review takes a neutral and practical look at what the app does well, where it performs consistently, and who is most likely to find it useful.

Keepa is purpose-built for Amazon and does not attempt to cover other retailers. Its strength lies in the depth of data it provides for Amazon listings specifically: rather than showing only the current price, it records and displays the full price history for a product going back years, covering Amazon’s own price, third-party new and used seller prices, Warehouse deals, and Lightning Deal history across multiple Amazon regions. For shoppers who want to verify whether a current Amazon price is genuinely a good deal relative to long-term historical pricing, Keepa provides more comprehensive data than most general-purpose price trackers.

The tool is available in both a free tier and a paid subscription. The free version covers core price history and basic alerts, while the subscription unlocks additional data layers including sales rank history and Buy Box tracking that are particularly useful for resellers and more analytical shoppers.

This review covers the key features, performance, and typical use cases for Keepa, based on hands-on testing using the browser extension and web dashboard.

What Is Keepa

Keepa is a Germany-based Amazon price tracking service that has been operating since 2013. It is available as a browser extension for Chrome, Firefox, Edge, Opera, and Safari, and as a web-based dashboard at keepa.com. A mobile app is also available for iOS and Android.

The service records price data from Amazon product listings continuously and stores that data in a searchable database, allowing users to view how a product’s price has changed over any period since Keepa began tracking it. This can include years of historical data for well-established products, which is significantly more extensive than the 30 to 120-day windows provided by most competing tools.

Keepa covers nearly all global Amazon marketplaces including the US, UK, Germany, France, Italy, Spain, Japan, Canada, Australia, India, and others. Free users can access basic price history charts and set a limited number of price drop alerts. The paid subscription unlocks full data layers including sales rank history, Buy Box price tracking, and extended alert capacity, and is billed on a monthly basis.

Key Features

Detailed Price History Charts Keepa embeds an interactive price history chart directly on Amazon product pages via the browser extension. The chart displays price over time for multiple data types simultaneously, including Amazon’s price, third-party new seller prices, used seller prices, and Warehouse deals. In tested scenarios, the chart loaded reliably on Amazon product pages and clearly displayed long-term price trends, making it straightforward to identify whether a current price was at a historical low, high, or somewhere in between.

Multi-Variant Price Tracking Unlike basic price trackers that follow only the listed price, Keepa tracks several price variants for each product: Amazon’s direct price, the Buy Box price, third-party new and used prices, and Amazon Warehouse deals. In tested scenarios, toggling between these data layers on the chart provided a more complete picture of the actual purchase options available for a given product over time.

Price Drop Alerts Users can set target prices for specific products and receive notifications when the price drops to or below the threshold. Alerts can be delivered by email, browser notification, or mobile push notification depending on the user’s settings. Free users have a limited number of active alerts; the paid subscription removes this cap. In tested scenarios, alerts were delivered promptly after a tracked item’s price changed to meet the set condition.

Sales Rank and Buy Box History (Subscription) The paid subscription unlocks sales rank history charts, which show how frequently a product has sold over time — a feature particularly useful for resellers evaluating whether a product has consistent demand. Buy Box history shows which sellers have held the featured offer position over time and at what prices. In tested scenarios, these additional data layers loaded correctly alongside the standard price history charts on Amazon product pages.

International Amazon Marketplace Support Keepa covers nearly all Amazon regional marketplaces, and users can switch between regions on the web dashboard to compare pricing history across different countries. In tested scenarios, switching between marketplace regions returned accurate historical data for the selected region, which is useful for shoppers or sellers who operate across multiple Amazon locales.

Product Tracking Lists Users can maintain watchlists of tracked products through the Keepa web dashboard, organized by category or custom list. In tested scenarios, adding products to tracking lists from the browser extension was straightforward, and the dashboard provided a clear overview of all tracked items and their current status relative to set alert thresholds.

Browser Extension Integration The Keepa browser extension integrates directly into Amazon product pages, adding the price history chart below the standard product information without requiring the user to navigate away from Amazon. In tested scenarios, the extension loaded charts reliably on Amazon product pages across the regions tested and had no noticeable negative impact on browser performance.

Performance Review

Price History Chart Accuracy and Depth In tested scenarios, Keepa’s price history charts displayed accurate historical data for Amazon product listings, including multi-year history for established products. The ability to view long-term trends — rather than just the past 30 to 120 days available in most other tools — was the most practically useful aspect of the service for evaluating whether a promotional price represented a genuine historical low. Data coverage was consistent across the major product categories tested.

Alert Reliability In tested scenarios, price drop alerts delivered correctly and promptly when a tracked product’s price moved to meet the set condition. Email alerts included clear product information, the triggering price, and a direct link to the Amazon listing. No missed or delayed alerts were observed for items that experienced price changes during the testing period.

Browser Extension Performance In tested scenarios, the Keepa browser extension loaded price history charts consistently on Amazon product pages without causing noticeable slowdowns or page rendering issues. The extension handled product pages with complex layouts and multiple seller listings without instability. Chart rendering remained smooth even for products with extensive historical data spanning several years.

Web Dashboard Usability In tested scenarios, the Keepa web dashboard loaded tracking lists, product search results, and historical data accurately. Navigating between tracked items, setting alert thresholds, and switching between Amazon marketplace regions worked reliably. The dashboard’s data density is higher than most comparable tools, which suits analytical users but may require a short adjustment period for users accustomed to simpler interfaces.

Pricing & Plans

Keepa offers a free tier alongside a paid monthly subscription.

Free Plan The free plan provides access to basic price history charts via the browser extension and web dashboard, covering Amazon’s price and third-party seller prices over the full available history. A limited number of price drop alerts can be set. This tier suits casual Amazon shoppers who primarily want to check price history before making a purchase decision without needing the additional data layers.

Keepa Subscription The paid subscription unlocks the full set of data layers including sales rank history, Buy Box price tracking, extended product data, and an increased number of active price alerts. It is billed monthly with no long-term commitment required. This tier is most relevant for frequent Amazon shoppers who want to track large numbers of products simultaneously, resellers who need sales rank data to evaluate product demand, and analytical users who want the complete data picture for each listing.

The subscription price is modest compared to the depth of data it provides, and users who make regular higher-value purchases on Amazon may find the additional data layers justify the cost relative to the potential savings from better-timed purchases.

Use Cases

Verifying Whether an Amazon Sale Price Is Genuine Keepa’s most common use case for regular shoppers is checking whether an Amazon sale or promotional price is actually lower than the product’s historical typical price. The long-term price history chart makes it immediately clear whether a claimed discount is meaningful or whether the item frequently sells at the same price.

Timing Purchases for Long-Term Price Lows For planned non-urgent purchases, the price history chart helps users identify seasonal patterns or recurring low-price periods for a specific product. Setting a target alert at or near a historical low allows users to wait for a confirmed price drop rather than purchasing at a potentially inflated price.

Reseller and Amazon Seller Research Keepa’s subscription-tier sales rank history and Buy Box tracking are particularly valuable for Amazon resellers and sellers evaluating product viability. Sales rank history provides an indication of consistent demand over time, and Buy Box history shows competitive pricing patterns for a listing.

Tracking Multiple Products Simultaneously The product watchlist feature and the increased alert capacity on the paid tier make Keepa practical for users who want to monitor a large number of items at once — such as shoppers building a wishlist for a future event or resellers tracking inventory pricing across multiple categories.

International Price Comparison Across Amazon Regions For users who shop or sell across multiple Amazon marketplaces, the ability to view and compare price history across different regional stores provides useful context that single-region trackers cannot offer.

Pros and Cons

Pros:

  • Extensive price history going back years for established Amazon products, far beyond the 30–120 day windows of most competing tools
  • Tracks multiple price variants simultaneously including Amazon’s price, third-party sellers, used listings, and Warehouse deals
  • Covers nearly all global Amazon regional marketplaces
  • Free tier provides meaningful access to core price history charts without a subscription
  • Browser extension integrates directly into Amazon product pages without requiring a separate visit to a tracking site

Cons:

  • Exclusively Amazon-focused; does not cover other retailers
  • Full feature set including sales rank and Buy Box history requires a paid subscription
  • The data-rich interface has a steeper learning curve than simpler price tracking tools
  • Free tier limits the number of active price alerts
  • Mobile app experience is more limited than the desktop browser extension

Who Should Consider This App

Keepa is a practical option for frequent Amazon shoppers who want detailed, long-term price history data to make more informed purchasing decisions, resellers and Amazon sellers who need sales rank and Buy Box data to evaluate product demand and competition, and analytical users who want the most comprehensive price tracking data available for the Amazon marketplace specifically.

It is less suited for users who shop across multiple retailers and want a single cross-platform tool, casual shoppers who only occasionally check prices and do not need years of historical data, or users who find data-dense interfaces less approachable. For cross-retailer price comparison, a tool like Price.com or InvisibleHand would cover a broader range of stores.

For Amazon-focused shoppers and resellers who want the most detailed and historically extensive price tracking data available for the platform, Keepa is the most capable dedicated tool in its category.

Final Verdict

Keepa is the most data-comprehensive Amazon price tracking tool available for general consumer use. Its combination of multi-year price history, multi-variant price tracking, international marketplace support, and reliable alert delivery gives it a depth that no comparable free or low-cost tool matches for Amazon-specific research.

The Amazon-only focus and the steeper interface learning curve compared to simpler trackers mean it is not the right fit for every user. For shoppers and resellers who regularly make purchasing decisions based on Amazon pricing and want the most complete historical picture available, however, Keepa is an exceptionally capable and reliable tool that delivers consistent value at every tier.

For serious Amazon shoppers and resellers looking for a dependable, data-rich price tracking tool with extensive historical coverage, Keepa is the most thorough option available.
