About

BSRx shows you what Amazon products actually sell.

Visit any product page and BSRx instantly pulls the Best Sellers Rank and turns it into real numbers: estimated monthly sales, monthly revenue, price, reviews, and category rankings. It all shows up right on the page. No accounts, no API keys, nothing to configure.

On search results and bestseller pages you get a full comparison table so you can size up an entire niche at once.

Built for KDP authors picking their next book niche, FBA sellers hunting for products worth sourcing, and anyone who's ever looked at an Amazon listing and wondered "how many of these actually sell?"

BSRx runs 100% in your browser. Nothing is tracked, nothing is sent to a server. It reads the same public data Amazon shows on every product page and does the math locally.

Works on amazon.com, amazon.co.uk, and amazon.ca. Free, no limits.

BSRx uses Amazon affiliate links. When you click a product link through BSRx, we may earn a small commission at no extra cost to you. This helps support continued development of the extension.
