Amazon hides Best Sellers Rank on search results, so you open listing after listing to see what sells. BSR Overlay puts the rank on each result card, colour-coded by thresholds you set. It loads ranks only for the cards you can see, and caches them, so scrolling back is instant. You choose how many requests run at once. One declared permission: storage, for your settings. It runs only on Amazon marketplace pages. No server, no analytics, no account. 21 marketplaces.
Hi Product Hunt 👋
Amazon search results don't show Best Sellers Rank. To size up a niche, you end up opening product page after product page just to read one number.
BSR Overlay puts that number on the result cards.
A few choices made on purpose:
• It only loads ranks for the cards you can actually see. Scroll, and the next ones fill in. Ranks are cached, so scrolling back is instant.
• You set how many requests run at once. Lower is gentler on Amazon.
• Green / amber / grey at a glance. Both cut-off points are yours to change.
• The declared permission list is one line: storage (for your settings). It runs only on Amazon marketplace pages. There is no server behind it, no analytics, no account.
All 21 marketplaces were checked on the live sites rather than assumed from a table. Rank formats differ by country (#94 / 1,466位 / Nr. 1.234 / 2.037. sırada) and all four are handled.
I'd like to hear where it breaks for you, which marketplace looks off, or what you'd want next.
