BuyHub

BuyHub is a search engine for collectors and resellers that covers more than 100 marketplaces worldwide, such as eBay, Vinted, Mercari, Facebook Marketplace, Yahoo Auctions, Kleinanzeigen and Xianyu. Features: - Search more than 100 marketplaces in 110 countries from a single interface. - Radars that keep searching for you around the clock and notify you the moment a matching item is listed, in your browser and on your phone. - Several search terms across several marketplaces at the same time, with duplicates dropped. - Every result translated into your language, with prices converted to your currency. - Filters the marketplaces do not offer: positive and negative keywords, seller country, listing date. - Saved searches you can open with one click. - Auction alarms that warn you hours or minutes before an auction ends. BuyHub works on the web, as a browser extension for Chrome and Firefox; apps for iPhone and Android are coming soon. The free plan includes eBay and Catawiki in full, one radar and auction alarms; paid plans unlock every marketplace, more radars and faster checks.

Collectors (retro games, trading cards, Lego, watches, sneakers, vintage clothing) who hunt items on second-hand marketplaces in many countries, and resellers who source stock below market price and need to know the moment a matching listing appears.
