GrailHound: Marketplace Alerts

GrailHound scans eBay, Facebook Marketplace, Mercari, Vinted, Grailed and dozens more resale marketplaces around the clock, so you don't have to. We alert you when a new listing matches your search: on your phone, your browser or via email. Your first tracker is free.

GLOBAL COVERAGE
eBay · Facebook Marketplace · Craigslist · Mercari · Vinted · Grailed · Depop · Poshmark · OfferUp · Whatnot · Kijiji · Mercado Libre · Kleinanzeigen · Leboncoin · Wallapop · Marktplaats · Gumtree · Subito · Tradera · Willhaben · OLX · Yahoo Auctions Japan · Mercari Japan · Rakuten · Rakuma · Carousell · Tokopedia · Bunjang and more, across five continents.

HOW IT WORKS
1. Tell us what you're after: a keyword ("jordan 4 white cement", "canon ae-1", "vintage carhartt jacket") and pick your marketplaces.
2. We scan around the clock.
3. We deliver the listings to you: phone notifications, email, or save them in the in-app feed.

ONE FEED, 50+ MARKETPLACES
Matches from all your trackers land in one feed instead of twelve open tabs. A saved search on eBay only covers eBay; GrailHound runs your search across every marketplace at once.

ALERTS WORTH OPENING
Set a price cap and listings over your budget never reach you. Block words like "broken" or "for parts". For anything more specific, describe it in your own words ("original 2002 release only, no reissues") and the AI filters every listing for you.

LOCAL DEALS
Facebook Marketplace, OfferUp, Craigslist and more. We have your local deals covered.

BUILT FOR YOUR HUNT
Catch eBay auctions and Whatnot drops while the bidding is still quiet. Be first to underpriced listings on Mercari, OfferUp and Depop. Track Vinted, Grailed, Poshmark and Kleinanzeigen for vintage clothing, designer resale, thrift and secondhand finds.

MAINSTREAM TO NICHE
Furniture, car parts, cameras, kids' gear, tools, sneakers, trading cards, watches, vinyl records, vintage clothing, LEGO, games, advertising, memorabilia. If you can name it, you can track it with GrailHound.
