Price Mantis is an automated Amazon tracking platform built to uncover fake discounts. Track full price history across direct Amazon, third-party new, and used listings. Unlike trackers that stripped out data, Price Mantis monitors sales rank (BSR) velocity and review score changes to help you spot quality drops or artificial review surges. Set instant price drop alerts, sync your Amazon wishlists, and view charts on product pages with a clean, privacy-first browser extension.
