The Auctioneer brings auction sessions and lots from public platforms and jurisdictions into one searchable index, updated throughout the day. Its agents remember what you're looking for and tell you when something is worth your attention. You decide, and you complete the purchase on the platform.
Search across every auction house in the index to find a lot and others like it. Tell it what you're looking for in plain language and get a ranked list with estimates and closing times.
Add lots to your watchlist and get updates on new bids, estimate changes, withdrawn lots and changes to auction dates.
Set your price and let The Auctioneer watch the bidding. Get notified when the current bid crosses it, so you can decide at the moment it matters.
On the roadmap. Tell it what you want and the most you would pay, and it prepares everything you need to bid: comparable sales, where the lot is likely to close and your limit. You place the bid on the platform.
Whether you buy at auction for work or as a hobby, there are plenty of platforms to choose from. We took the five that buyers ask us about most, compared them using the same five questions, and put The Auctioneer through the same test.
An online marketplace for fine art, antiques and collectibles, with timed and live sales from thousands of auction houses and bidding in the browser. Its sold-price archive is free to search.
Best for: buying art and antiques from houses that list on it.
Similar to LiveAuctioneers, with a strong range of European auction houses. Twelve months of past results are free with an account; the longer archive is paid.
Best for: European auctions and extensive historical sales prices.
The UK's main bidding platform for regional auction houses, covering everything from country house sales to trade clearances. It offers broad coverage across the UK, with fewer auctions elsewhere. You can leave a max bid and it bids for you, up to that amount, on that lot.
Best for: UK regional houses in one place.
With around a billion past sale prices from eBay and auction houses, it's a useful reference for checking what similar items sold for.
Best for: checking a price before you bid.
A search engine for art, design and collectibles across more than 3,000 auction houses and galleries, with links to bid directly with each house. Its database of realized prices is free.
Best for: discovering what is coming up across art houses.
We index auction sessions and lots across 57 platforms, alongside government surplus, vehicles, machinery and trade sales that art and antiques sites do not cover. We are not a marketplace and we do not bid: you place the bid on the platform.
Best for: anyone who buys across more than one platform or category and wants to spend minutes a week on it, not hours a day.
Where we are weaker: we do not host bidding, so you complete your purchase on the original platform. Our sales price history starts in 2026, so other platforms offer more historical data for art and antiques.
Marketplaces are good at covering the auctions they host, but leave you to check other platforms yourself. Price databases show what sold in the past, but not what's closing tonight. Alert services keep watch, but you still need to know where to look.
None of the others puts art, vehicles, machinery and government surplus in one plain-language search. That is the gap The Auctioneer is built to fill: one index, one search, and comparable sales with an indicative margin before you bid.
Assessments reflect each product's public pages in October 2026. Coverage figures for The Auctioneer are from the 27 August 2026 production snapshot. Names are the property of their owners.
BlueMesa Systems builds AI and software for physical markets where information is scattered across platforms and buying still takes too much manual work. We bring that information into one structured index, make it searchable in plain language, and build agents that remember what you want and tell you when it matters. Auctions come first. We do not bid, buy or trade on anyone's behalf, take positions or hold assets: the user decides and completes every purchase on the platform.
