The best online auction site besides eBay depends on what you want to buy or sell. For live auctions and marketplace sales, consider Whatnot; for special objects that go through expert review, consider Catawiki. They serve different needs, and available evidence does not establish a universal winner or an exhaustive ranking.
Which auction site fits your needs?
Start with the item and the way you want to transact—not a claim that one site is best for everyone. Before bidding or listing, compare category fit, whether the platform serves your location, the auction format, all buyer or seller fees, shipping or pickup arrangements, and the relevant policies. Platform terms can change, so check the current listing and checkout information.
| Platform | Worth considering for | Format and selection | Costs to check |
|---|---|---|---|
| Whatnot | People interested in live selling or bidding, as well as marketplace sales in supported categories | Live show sales and non-live marketplace sales | Commission by category, market, and sales tier; separate payment processing; taxes and shipping |
| Catawiki | Special objects and collectors comfortable with expert selection | Experts review submissions and select objects for auction | Seller success fee and any applicable VAT; buyer protection fee; shipping and possible import VAT |
This is a use-case comparison, not a head-to-head endorsement. The available information does not provide common measures for comparing inventory depth, buyer protection, or total cost across the two platforms.
Whatnot: live auctions and marketplace sales
Whatnot supports sales through live shows and a non-live marketplace. Its seller fees depend on category, market, and sales tier, so a rate quoted for one seller or location may not apply to another.

Whatnot’s seller-fees page, dated October 1, 2026, says its new commission structure took effect for existing sellers on September 21, 2026. It describes a four-week sales window: sales during that period determine the commission tier for the next period. Commission is calculated on the item’s sale price. Payment processing is separate and is calculated on the buyer’s total order value, including shipping and taxes, plus a fixed fee. Check the rate card and applicable rules for your market before listing; the policy does not establish one global rate. Whatnot seller fees and the fee calculation details explain the policy.
Catawiki: expert-reviewed auctions for special objects
Catawiki describes itself as a marketplace for special objects. Experts review submissions and select objects that meet its standards for auction. It says submitting an object is free; a seller success fee applies if the object sells, and VAT may be added where applicable. The stated fee terms apply to objects submitted on or after August 17, 2026. Review the current seller terms for the fee that would apply to your item. Catawiki’s seller information gives its submission and selling details.
Catawiki’s Help Centre states that its buyer protection fee is 9% of the final bid plus €3. The calculation excludes shipping. Shipping and, where relevant, import VAT can raise the amount due, so use the checkout total rather than the bid alone to decide what you can afford. Catawiki’s buyer protection fee explanation describes the charge.
Catawiki’s seller page also reports more than 10 million buyers, more than 240 experts across over 22 categories, and coverage in 60 countries and 17 languages. These are company-reported figures, not independently audited audience or reach statistics. They are not a guarantee that a particular item will be accepted or sell.

A headline fee rarely tells you the total. For a seller, distinguish the fee charged on the item price from charges calculated on the order total. For a buyer, add the buyer fee, shipping, taxes, and any import charges to the bid. These examples show why the calculation base matters; they do not establish which platform is cheaper overall.
- Whatnot sellers: Verify the category and market rate, how the four-week tier is determined, the separate payment-processing charge, and any taxes or shipping obligations.
- Catawiki sellers: Check the success fee for the submission date and whether VAT applies. A free submission does not mean a sale is fee-free.
- Catawiki buyers: Include the 9% of final bid plus €3 buyer protection fee, then add shipping and any applicable import VAT shown at checkout.
Pre-bid and pre-listing checklist
- Geography: Confirm that the platform supports your country and that the specific listing can be bought or shipped to your location.
- Final amount: Calculate fees using the platform’s stated base, then check the checkout or seller terms for taxes, processing charges, and other costs.
- Delivery: Confirm shipping cost, delivery restrictions, estimated arrangements, and whether local pickup is available before bidding.
- Payment and policies: Review payment deadlines, cancellation and return rules, dispute procedures, and the platform’s buyer or seller protections.
- Item details: Read the condition description and inspect available photos. For a seller, confirm that the item fits the platform’s category and selection requirements.
What about other auction sites?
HiBid, ShopGoodwill, Heritage Auctions, and auction-house aggregators may be relevant depending on the item, but current official details were not established here for a reliable comparison of their fees, protections, shipping, and geographic availability. Treat them as options to investigate, not as ranked recommendations: verify those details directly on the relevant site before bidding or listing.
