Grabbit

Grabbit aggregates listings from multiple second‑hand platforms—including Facebook Marketplace, Craigslist, OfferUp, Depop, and Mercari—into a single search interface. Users enter a query once and the service retrieves real‑time results from all supported marketplaces, displaying them side by side with filters for price, distance, and condition. Selecting a result redirects the buyer to the original site for purchase.

The tool also provides a “GrabScore” that evaluates each listing against similar items across the included marketplaces, offering a confidence‑rated estimate of whether the price is a good deal. Scores are shown with a value range and a verdict, helping users gauge price fairness without manually comparing listings.

A free account lets users save searches and receive notifications when new items match their criteria, while the site also features category browsing and a “trending near you” view of popular local listings. No account is required for basic searches.
