Overview

Product summary

Review the store description, core capabilities, and common use cases.

Buying or selling on Facebook Marketplace, Craigslist, or OfferUp? Marketplace Guardian helps you stay safe and save time — completely free, no account needed.

🛡️ SCAM CHECK

Highlight any listing or message and right-click "Check this for scams," or paste it into the popup. You get a clear risk score and the exact red flags — verification-code tricks, off-platform payment (Zelle / Cash App / wire / gift cards), fake shipping on a local pickup, deposit-to-hold scams, and more. It even weighs how long the seller has had their account and their star rating.

✍️ LISTING WRITER

Describe your item in a sentence and get a ready-to-post title, description, and a sensible suggested price.
