About

I build small Chrome extensions that each do one job. There are three so far, all for Amazon: expanding search suggestions into a keyword list, showing Best Sellers Rank on search results, and exporting order history to CSV. I keep the permission list short and don't send data to a server. If something breaks on your marketplace, I'd like to hear about it.

BSR Overlay for Amazon - The rank Amazon doesn't show on its search results

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.
