Prowl by Owl & Twig is a search tool for vintage collectors and resellers. Type a piece once and it builds that search for every major vintage marketplace on one screen, including ShopGoodwill, Facebook Marketplace and Craigslist. It is built by Matt at Owl & Twig Vintage, a family vintage shop in Michigan.

Which marketplaces does Prowl search?

eBay, Etsy, Mercari, Mercari Japan, Poshmark, Depop, Grailed, Ruby Lane, Chairish, 1stDibs, Reverb, Whatnot, Vinted, Shop, Bonanza, eCrater, AbeBooks, AptDeco, OfferUp, Facebook Marketplace, ShopGoodwill, Salvation Army, EstateSales.net, HiBid, LiveAuctioneers, CTBids, Heritage Auctions, Invaluable, Craigslist and eBay Sold, for what pieces actually sold for. ShopGoodwill, eBay, Etsy, Chairish, Poshmark, Vinted, Grailed and Salvation Army results show right on the page; the rest open in their own tab. Instagram sits beside them as a hashtag search.

How do I find antique shops and estate sales near me?

Tap Near me at the foot of the page. Around you lists the shops near you, and under More ways to look you can tap a store type, like antique stores, thrift stores, estate sales or flea markets, and a map search opens around you in Google Maps or Apple Maps. Save your city there too, and Craigslist and Facebook search that area.

Yes. Searching is free: 3 searches to try it, then a free sign-in with your email (a 6-digit code, no password) to keep going. Your Den keeps 5 hunts of your own for free, or up to 100 with Prowl Pro. Email alerts are optional: free for 5 hunts, as often as you like, or up to 100 hunts with Prowl Pro.

Does it work on my phone?

Yes. Built mobile-first. Add it to your home screen, and allow pop-ups if you use Open all. On a phone, Facebook opens in your browser so the search sticks, so log in to Facebook there once.

How does Price Check work?

One tap opens eBay's sold listings for your term — actual sale prices from the last 90 days, the most accurate read on what a piece is worth right now. Asking prices lie; sold prices don't.

What if nothing sold in 90 days?

That happens with genuinely rare pieces. Price Check has a second button for three years of deep comps via eBay's Terapeak research — free with any eBay account. Open it in your browser rather than the eBay app, or the date range gets dropped.
