Price Mantis is an Amazon price-tracking platform that helps shoppers assess product value and find better times to buy. Focused on the Amazon US store, it provides price history charts showing maximum, minimum, and recent prices, helping users identify genuine bargains and spot inflated sale discounts. Shoppers can also monitor review counts and scores over time, check rating trends for possible quality changes or unusual review activity, and view Best Sellers Rank data to gauge demand and sales velocity.

To get started, users search by Amazon product link or ASIN, review the product’s tracking profile, and add items to a watchlist. Price Mantis can then send notifications when prices drop. Its browser extensions for Chrome, Firefox, and Edge bring tracking tools into the shopping experience; the company says they use minimal required permissions and do not secretly scrape Amazon in the background. International tracking support is planned, while current coverage is limited to Amazon US. Price Mantis also participates in Amazon’s affiliate program, earning advertising fees through qualifying links.
