EverBee

While you browse Etsy, it puts estimated monthly sales and revenue on other people's listings and shops, so you can see what actually sells.

EverBee is a US-built research tool for Etsy. It comes as a browser extension plus a web app; the extension runs only in Chrome and its relatives on a computer (Edge, Brave) — not on a phone and not in Firefox, and it is aimed at people who sell on Etsy or are thinking about starting — makers, sellers of digital files, and print-on-demand designers alike. The whole interface is in English — and one practical note that follows from that: Etsy shoppers search mostly in English, so keyword research is worth doing in English rather than your own language.
