Smarter search, filters, deal tracking and alerts for Facebook Marketplace. Find the listings you actually care about. MarketScout improves Facebook Marketplace with smarter filtering, faster deal discovery, saved searches, listing history and optional new-match alerts — directly inside Marketplace. KEY FEATURES • Smarter keyword search Type a single keyword such as Toyota and MarketScout can narrow Facebook's own Marketplace search automatically, instead of waiting for hundreds of unrelated listings to load. • Advanced filters Filter loaded Marketplace results by price, keywords, vehicle year, mileage and location. Exclude unwanted words and optionally hide listings where important details cannot be detected. • Deal Feed See matching listings in a focused feed and sort them by newest seen, cheapest price, highest price, newest vehicle year, lowest mileage or biggest detected price drop. • Saved searches Save your filter settings together with the Marketplace search URL so you can return to useful searches quickly. • New-listing alerts While a Marketplace tab is open, MarketScout can notify you when a new matching listing appears. • Price history MarketScout remembers when it first saw a listing and can highlight detected price drops. • Relist detection High-confidence relist detection can flag listings that appear to be the same item posted again with a different listing ID. • Hide the noise Hide rejected listings, duplicates and promoted/advertising cards. • Light and dark themes Use System, Light or Dark mode. PRIVACY FIRST MarketScout processes Marketplace listing information locally in Chrome. Saved searches, listing history and preferences are stored locally on your device. MarketScout does not send your Marketplace data or usage activity to the developer, does not sell user data and does not use personalized advertising. IMPORTANT MarketScout works with information Facebook has loaded into the browser. Facebook may change Marketplace's interface or available listing information at any time. MarketScout is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Meta or Facebook. Facebook and Facebook Marketplace are trademarks/services of Meta Platforms, Inc.
