Overview
Real sold comps, scam flags, and a buy/skip/negotiate verdict for every listing on Facebook Marketplace, Craigslist, and OfferUp.
FairShake is a "should I buy it?" tool for used marketplaces. Open any listing on Facebook Marketplace, Craigslist, or OfferUp and one click gives you real sold comps — the actual prices the same item recently sold for, not asking prices — plus a clear buy, skip, or negotiate verdict with the math shown, and scam flags for seller red flags, photo issues, and identity mismatches. The verdict appears in a side panel without leaving the marketplace, so you know what something is really worth before you message a seller or drive across town. Built for buyers who don't want to overpay and resellers who need to move fast. FairShake is free during public beta — just sign in with your email at fairshake.app to get started.
