BSR Spy for Amazon

Researching products on Amazon means opening listing after listing just to check how well each one sells and how new it is. BSR Spy for Amazon puts both facts under every product’s picture as you scroll a search: its Best Sellers Rank (BSR) and the date it was first available. Spot proven sellers, newer listings with early traction and crowded niches at a glance, without clicking into a single product. Free, no account needed. It works in your own browser on amazon.com search pages and collects and sends nothing. BSR Spy is independent and is not affiliated with Amazon.
