Sift: Facebook Marketplace Smart Filters, Deal Alerts, Price Tracker & More

The smarter way to shop local. Sift is a free extension that cleans up Facebook Marketplace and Kijiji, flags likely scams, shows you which prices are fair, and alerts you the moment something new is listed. No account, no ads, no tracking. Install it, open a search and Sift gets to work. ✓ Alerts the moment a new listing matches your search ✓ Every price drop, with the full price history ✓ Fair-price check: below, at or above typical for your search ✓ Likely scams flagged in plain words, before you message ✓ Sponsored posts, dealers, wanted ads and junk hidden ✓ Filters for words, price, listing age and distance ✓ Built-in checks for cars, bikes, phones, LEGO and trading cards BE FIRST TO THE BEST DEALS • New-listing alerts: watch up to 10 searches and get a notification as soon as a matching listing goes up, even with the tab closed. • Price drops: Sift remembers what every listing cost, marks each drop and shows the full price history on hover. • Fair price: each listing is compared with similar ones in your search and marked Below typical, Typical or Above typical. • Motivated sellers: see how long a listing has been up and whether it was reposted. SPOT A BAD DEAL BEFORE YOU MESSAGE • Scam flags in plain words: asks for money before you see it, wants to talk off the site, priced far below typical, ships only on something people buy in person. • Every listing gets a short "check this" list and one-click links to eBay sold prices and image search. SEE ONLY WHAT YOU'D ACTUALLY BUY • Hide sponsored posts, Kijiji Top Ads, dealers, wanted ads and shipped-only listings. • Block words like "financing" or "rent to own", or require the words you want. • Set a price range, a maximum listing age and a distance limit from your home. • Dim, hide or outline what you've already seen, and open every search newest first. CHECKS FOR BIG PURCHASES • Cars: model-year and mileage limits, salvage and rebuilt titles hidden (Quebec wording too), dealers tagged or hidden. • Bikes: a frame-size filter and a stolen-bike check on Bike Index. • Phones: activation-lock, blacklist and financing warnings, plus an IMEI check. • LEGO: set numbers read from the title, the BrickLink price guide and knock-off warnings. • Trading cards: PriceCharting and TCGplayer prices in one click. SET UP IN A MINUTE Start a search for a car, bike, LEGO, trading cards or a phone and Sift sets the right filters for you. Save any setup as a preset and switch from the toolbar.
