koqi.

Every used item worth buying. One place.

Koqi gathers every legitimate used listing in America — from every marketplace, dealer and auction — into one honest search. If it's for sale, you can find it here. If it's here, it's actually for sale.

Every listing. Every marketplace. One search.

Each category lives on its own specialist site — that is where the listings are, and where they are canonical. Koqi is the front door to all of them.

Why Koqi

Marketplaces show you only their own listings, and half of them are already sold. Koqi is built on four commitments instead:

Completeness

Every source in one search — not just one marketplace's own listings. eBay, Facebook, Craigslist, dealers and auctions, gathered together.

Honesty

Listings are verified live, and dead ones are closed quickly. What you see on Koqi is actually still for sale.

Real prices

Sold-price history sits next to asking prices, so you can see what things really sell for — not just what sellers hope for.

Straight to the seller

Every listing links back to its seller. Koqi never inserts itself into the deal — you talk to the seller, always.

How it works

STEP 1

We gather

Every marketplace, dealer site and auction we cover is read continuously — new listings land fast.

STEP 2

We verify

Each listing is checked against its source. Prices and availability are re-read, and listings that die at the source close here too.

STEP 3

We dedupe

The same item listed in three places becomes one page with every sighting joined — never three copies competing with each other.

STEP 4

You go to the seller

Every page links straight back to the original listing. Set an alert and we email you the moment a match appears.
