The world of online auctions has changed dramatically over the past few decades, driven by better technology and a generation of buyers and sellers who are completely comfortable transacting online.
Today there are dozens of bidding apps and websites to choose from, each with its own categories, fee models, and tools.
In this guide we break down the top 10 auction apps in 2026, compare the best DealDash alternatives, and explain the different auction models so you can pick the right platform, whether you want to bid or build.
We also cover the best free auction apps, live auction apps, penny auction sites and reverse auction platforms, plus what it costs to launch your own auction site and the best online auction software to do it.

The top 10 auction apps in 2026
1. eBay
eBay is still the most recognised and widely used auction site in the world. Founded in 1995, it paved the way for online auctions and built a loyal global following. Sellers can auction almost anything, from vintage collectibles and electronics to cars.

With well over 100 million active buyers worldwide, eBay’s strength is its sheer reach, diverse categories, and a polished mobile app with personalised recommendations and push notifications for auction updates. It remains the default starting point for most buyers and sellers.
2. Heritage Auctions
Heritage Auctions is the largest auction house in the United States, specialising in fine art, rare collectibles, coins, and luxury items. It’s a haven for serious collectors hunting pieces that are hard to find elsewhere, and its app makes it easy to join live auctions and bid from anywhere. Appraisal services and expert guidance make it especially popular with investors.
3. BiddingForGood
BiddingForGood is a charity-focused auction platform that lets nonprofits raise funds while buyers support causes they care about. Listings range from travel packages and event tickets to unique experiences, so bidders get to combine philanthropy with shopping, a combination that has earned it a devoted following.
4. Auction.com
Specialising in real estate, Auction.com is the leading auction app for residential and commercial property, including foreclosures and bank-owned homes that investors love for the discounts. Users can filter by location, budget, and property type, then bid directly in the app. Its huge listing volume and streamlined bidding have made it a favourite among real estate investors and house flippers.
5. Charitybuzz
Charitybuzz also blends auctions with philanthropy, but focuses on luxury experiences and celebrity interactions such as meet-and-greets, VIP event tickets and private dinners with industry leaders. By partnering with high-profile charities, it appeals to bidders chasing once-in-a-lifetime experiences for a good cause.
6. Tophatter
Known for fast-paced “lightning” auctions, Tophatter sells items in just a few minutes of bidding. Its catalogue spans gadgets, jewellery, beauty products, and household goods, and the app is built to be quick, interactive, and gamified. It suits users who want instant gratification and frequent bargains. Learn more about sites like tophatter
7. Sotheby’s
Sotheby’s is one of the oldest auction houses in the world, with an app for bidding on high-value items from fine art to vintage wine and luxury cars. It caters to affluent collectors and provides deep item detail, including provenance, artist information and historical context, in an elegant interface built for sophistication and exclusivity.
8. Catawiki
Catawiki is a European platform specialising in unique, hard-to-find items: classic cars, rare comics, antique furniture. Every auction is curated by expert auctioneers, so quality is consistent and niche collectors keep coming back. Ideal for buyers who value rarity and curation over volume.
9. DealDash
DealDash takes a different approach as a “pay-to-bid” (penny auction) site. Users buy bids in advance and spend them competing for electronics, appliances, and household goods. If they don’t win, they can buy the item outright at a “Buy It Now” price with the cost of their bids deducted. The model appeals to people who enjoy the thrill of bidding but want a safety net, and it’s known for daily deals and low winning prices. (Looking for sites like DealDash? See our dedicated DealDash alternatives section below.)
10. PoliceAuctions.com
PoliceAuctions.com sells government surplus and seized assets such as jewellery, electronics, collectibles and vehicles, often at a fraction of market value. Its penny-auction format makes it a go-to for bargain hunters who enjoy the competition and the chance to score quality items cheaply.
Best auction apps for mobile: iOS and Android compared
Most people searching for auction apps or bidding apps want something they can install on their phone and bid from, not just a website they open in a browser. There is a real difference between the two. Some platforms have a proper native app with push notifications for outbid alerts, which matters a lot when an auction closes while you are away from your desk. Others only have a mobile site, so you have to keep the tab open and refresh.
Here is how the top mobile auction apps compare on availability and what the app actually does well.
| Auction app | iOS | Android | Outbid push alerts | What the app is best at |
|---|---|---|---|---|
| eBay | Yes | Yes | Yes | Barcode listing, saved searches, full bidding |
| Whatnot | Yes | Yes | Yes | Livestream bidding, app-first experience |
| DealDash | Yes | Yes | Yes | Bid packs and BidBuddy auto-bidding |
| HiBid | Yes | Yes | Yes | Finding local auctions near you |
| Heritage Auctions | Yes | Yes | Yes | Joining live catalogue auctions |
| Catawiki | Yes | Yes | Yes | Browsing curated lots by category |
| Auction.com | Yes | Yes | Yes | Property search filters and bid tracking |
| Proxibid | Yes | Yes | Yes | Live equipment and industrial auctions |
| Sotheby’s | Yes | Yes | Yes | High-value lots with full provenance detail |
| Charitybuzz | Mobile web | Mobile web | Email only | Experiences and charity lots |
If you bid often, the two features worth checking before you commit to any bidding app are automatic (proxy) bidding and outbid notifications. Proxy bidding lets you set a maximum and walk away, and the app bids on your behalf up to that limit. Without it you are stuck watching a countdown. Both features are standard in any serious auction app, and they are also the first things we build into custom auction platforms for clients.
Best free auction apps and free bidding sites
Not every auction app is free. The distinction that trips people up is between free to join and free to bid. Penny auction sites like DealDash let you create an account for nothing, but you have to buy bid packs before you can place a single bid, and those bids are gone whether you win or lose.
These are the genuinely free auction apps where placing a bid costs you nothing:
- eBay is the biggest free bidding app. Bidding is free for buyers, and you only pay if you win. Sellers pay listing and final value fees.
- Tophatter is free to bid on and runs very short auctions, so you get a result in minutes rather than days.
- HiBid aggregates thousands of traditional auctioneers and is free to register and bid, though individual auction houses add a buyer’s premium.
- Catawiki is free to bid on curated lots, with a buyer’s fee applied on top of the winning bid.
- Whatnot is free to join and bid in live streams, with no bid packs to buy.
- Listia uses credits you earn by listing your own items, so you can win things without spending cash at all.
One thing to watch on any free auction site: free to bid does not mean free to win. Buyer’s premiums of 10 to 25 percent are normal at traditional auction houses and aggregators, and shipping is usually on you. Always check the total before you bid, not just the hammer price.
Best live auction apps and livestream bidding platforms
Live auction apps are a different experience from timed auctions. Instead of a listing that ends at a set time, an auctioneer runs the lots in real time and you bid against other people as it happens. Livestream shopping has pushed this format hard over the last few years, and it now covers everything from sports cards to farm equipment.
These are the best live auction apps right now:
- Whatnot is the biggest livestream auction app, built around sellers running live shows in categories like trading cards, sneakers, comics and collectibles. If you are looking for live auction apps like Whatnot, this is the benchmark everyone else is measured against.
- HiBid streams live auctions from thousands of independent auctioneers, which makes it the best option for estate sales, farm equipment and local auctions.
- Proxibid handles live industrial and heavy equipment auctions with proper bidding tools for professional buyers.
- Heritage Auctions runs live catalogue auctions for coins, comics and fine art, with the app letting you bid from anywhere.
- Sotheby’s streams its live sale room for high-value art and luxury lots.
- LiveAuctioneers connects you to live sales at auction houses worldwide, covering antiques, jewellery and art.
The main thing to understand about live auctions is pacing. A lot can open and close in under a minute, so you need to have decided your maximum before it comes up. Most live auction apps let you leave an absentee bid in advance if you cannot attend the stream, which is the safer way to do it.
If you want to run this kind of format yourself, live bidding needs real-time updates and a bidding engine that can handle a lot of people hitting the same lot at once. That is very different from a standard timed auction, and it is worth planning for before you pick your software.
Best penny auction sites in 2026
Penny auctions, also called pay-to-bid auctions, work differently from every other site on this list. You buy a pack of bids up front, and each bid you place raises the price by a small increment and adds a few seconds to the clock. The winner pays the final price, which is often a fraction of retail, but everyone who bid and lost has still spent money on their bids.
The best penny auction sites and pay-to-bid platforms are:
- DealDash is the largest and most established penny auction site. Its Buy It Now option lets losing bidders put the cost of their spent bids toward buying the item outright, which softens the risk considerably.
- QuiBids is the classic direct competitor to DealDash and runs a similar bid pack model.
- PoliceAuctions.com uses a penny format but stocks government surplus and seized property, so the inventory is completely different from the usual electronics and appliances.
- Tophatter is not strictly a penny auction, but the fast format scratches the same itch without you having to buy bids first.
Are penny auction sites legit?
The established ones are legitimate businesses that deliver the items people win. The complaints usually come down to a misunderstanding of the model rather than fraud. Because you pay per bid, the site makes money from every bid placed on a lot, not just the winner, which is exactly how an item can sell for far below retail and still be profitable for them.
The practical advice is simple. Set a hard budget for a bid pack, treat that money as spent the moment you buy it, and only bid on items where the Buy It Now fallback would still be an acceptable outcome for you. If a site does not offer a Buy It Now option, your downside is much bigger.
Best reverse auction sites and platforms
A reverse auction flips the usual model. Instead of buyers competing to bid the price up, sellers compete to bid the price down. A buyer posts what they need, suppliers submit competing offers, and the lowest qualifying bid usually wins. It is the standard approach in procurement, freight and B2B services, and it is also used on freelance and home services marketplaces.
Common types of reverse auction platforms:
- Procurement platforms such as SAP Ariba and Coupa, where large companies run sourcing events and suppliers bid down on a defined spec.
- Government e-procurement portals, which run reverse auctions for public contracts and are usually open to registered suppliers only.
- Freight and logistics platforms, where carriers bid down on a load or lane.
- Service marketplaces, where tradespeople or freelancers quote against a posted job. The mechanic is a reverse auction even when the site does not use the term.
Reverse auctions work well when what you are buying is clearly specified and largely interchangeable between suppliers. They work badly when quality varies a lot, because the lowest bid is not automatically the best outcome. Most serious reverse auction software handles this by pre-qualifying suppliers before they are allowed to bid.
If you want to run reverse auctions on your own site, our WordPress reverse auction theme supports both standard and reverse formats, so buyers can post requirements and sellers can bid down on them.
Best DealDash alternatives compared
DealDash’s pay-to-bid model isn’t for everyone. If you like the discount-auction concept but want different inventory, lower risk, or a free-to-bid option, these are the best sites like DealDash in 2026.
| DealDash alternative | How it’s different | Best for |
|---|---|---|
| Tophatter | Free to bid; ultra-fast 90-second auctions | Impulse deals without buying bids |
| eBay | Free standard auctions, far bigger catalogue | Buyers who want maximum choice |
| PoliceAuctions.com | Penny model but government surplus inventory | Unusual, seized, and surplus items |
| Listia | Earn and spend credits instead of cash | Trading and clearing out unused items |
| HiBid | Aggregates thousands of traditional auctions | Estate sales and local auctioneers |
| QuiBids | Classic penny-auction competitor to DealDash | Direct pay-to-bid comparison |
The right alternative depends on whether you prefer free bidding (Tophatter, eBay), penny auctions (QuiBids, PoliceAuctions.com), or credit-based trading (Listia).
Auction sites like Tophatter and HiBid
DealDash is not the only platform people look for alternatives to. Tophatter and HiBid both have a specific format, and the sites that work as replacements are different in each case. You can learn more about sites like hibid.
Sites like Tophatter
People looking for auction sites like Tophatter usually want the same thing: short auctions, low prices, no bid packs, and a browsing experience that feels more like scrolling a feed than researching a purchase.
- Whatnot is the closest match in spirit. Live shows move fast and lots close in under a minute.
- eBay covers the same product categories with a much bigger catalogue, though auctions run for days rather than minutes.
- Listia works for low-value items where you would rather trade than spend.
- DealDash is worth knowing about as a contrast, since it is the pay-to-bid version of the same discount-hunting idea.
Sites like HiBid
HiBid is an aggregator. It does not run auctions itself, it lists auctions from thousands of independent auctioneers. If you want sites like HiBid, you want other aggregators rather than individual marketplaces.
- Proxibid aggregates live and timed auctions with a lean toward equipment, vehicles and industrial lots.
- LiveAuctioneers aggregates auction houses worldwide, strongest in antiques, art and jewellery.
- Invaluable covers a similar catalogue of fine art and collectibles from established houses.
- AuctionZip is the go-to for finding local estate and farm auctions by area.
Online auction sites other than eBay
eBay is the default, but it is not the best answer for every category, and its fees and competition put a lot of sellers off. If you are looking for online auction sites other than eBay, pick by what you are buying or selling:
- Collectibles and trading cards: Whatnot and Heritage Auctions
- Antiques and fine art: Catawiki, LiveAuctioneers and Invaluable
- Estate sales and local lots: HiBid and AuctionZip
- Real estate: Auction.com
- Vehicles: Copart, Mecum and Bring a Trailer
- Heavy equipment: Proxibid
- Government surplus: PoliceAuctions.com and GovDeals
The pattern is worth noticing if you are thinking about building something. eBay wins on breadth, but almost every profitable auction site launched in the last decade won by going narrow on a single category and serving it better.
Which online auction sites offer the widest range of categories?
eBay has the widest range of categories of any auction site, covering everything from electronics and clothing to vehicles, industrial equipment and property. Nothing else comes close on breadth.
After eBay, the broadest options are HiBid, which aggregates auctions across estate, farm, business liquidation and collectibles, and Proxibid, which spans equipment, vehicles, firearms, art and real estate. Catawiki is narrower but still covers a wide spread of collectible categories under expert curation.
If category breadth is what you care about, start with eBay and use the specialists as a second stop for anything eBay handles poorly, which is mainly high-value art, real estate and industrial equipment.
Other auction apps worth mentioning
Beyond the top 10, a few specialist platforms stand out for specific categories.
Proxibid
Proxibid connects buyers and sellers through live and timed auctions, plus buy-now and make-offer options. It specialises in heavy equipment, real estate, fine art, and collectibles, with robust technology, advanced bidding tools, and strong support for auctioneers. Its global reach makes it a trusted choice for professionals seeking specialised equipment.
Mecum Auctions
Mecum Auctions is one of the world’s largest collector-car auction companies, specialising in vintage and classic automobiles, motorcycles, and memorabilia. Founded in 1988, it’s a household name among enthusiasts, known for live bidding, TV broadcasts, and a high-energy atmosphere that draws both serious collectors and casual buyers.

Understanding the main auction models
Before you bid, or build, it helps to know how these platforms actually work, because the model determines the fees, the risk, and how the site makes money.
Standard (English) auctions are the eBay model: highest bid at close wins, and bidding is free. Penny / pay-to-bid auctions like DealDash and QuiBids charge for each bid placed, which is how they can sell items far below retail. Timed and live auctions (Heritage, Sotheby’s, Proxibid) mirror traditional auction houses, often with reserve prices. Reverse auctions flip the model so sellers compete to offer the lowest price, which is common in procurement and supported by our own reverse auction theme.
Which auction app is the most popular?
eBay remains the most popular auction platform worldwide. Its broad appeal, vast user base, and enormous range of categories keep it the top choice for buyers and sellers alike, backed by a reliable, user-friendly interface and strong buyer protections that make online bidding safe and enjoyable.

How much does it cost to build your own auction website?
If browsing these platforms has you thinking about launching your own, the good news is it’s far cheaper than it used to be. Broadly, there are three routes:
A ready-made WordPress auction theme is the lowest-cost option, typically a one-time license, and gives you core auction features (proxy bidding, reserve prices, anti-sniping, payments) out of the box. Dedicated online auction software sits in the middle, offering more advanced functionality and scalability for a serious marketplace. Fully custom development is the top tier, where an agency builds exactly what you envision, which is the right choice when you need bespoke rules, integrations, or a unique bidding mechanic.

Frequently asked questions
What is the most popular auction app?
eBay is the most popular auction app and website worldwide, thanks to its enormous user base and the widest range of categories. For penny auctions specifically, DealDash is the best known, and for live auctions Whatnot has grown fastest.
What are the best free auction apps?
The best free auction apps are eBay, Tophatter, HiBid, Catawiki and Whatnot. All of them let you place bids without buying bid packs first. Keep in mind that free to bid does not mean free to win, since buyer’s premiums and shipping still apply on most platforms.
What is the best live auction app?
Whatnot is the best live auction app for collectibles, trading cards and sneakers, thanks to its livestream format. For estate sales and local auctioneers, HiBid is the stronger choice, and Proxibid leads for live equipment and industrial auctions.
What are the best alternatives to DealDash?
The best DealDash alternatives are Tophatter and eBay (both free to bid), QuiBids and PoliceAuctions.com (penny-auction style), and Listia (credit-based trading). The right pick depends on whether you prefer free bidding or the pay-to-bid model.
Are penny auction sites like DealDash worth it?
Penny auctions can deliver real discounts, but because you pay for each bid, costs add up whether or not you win. They suit disciplined bidders who set a budget. Buy It Now options, like DealDash’s, reduce the risk by letting you recover spent bids toward a purchase.
What is a reverse auction site?
A reverse auction site flips the standard model so sellers compete to offer the lowest price rather than buyers bidding the price up. Buyers post what they need and suppliers bid down against each other. It is most common in procurement, freight and service marketplaces.
How much does it cost to build an auction website?
A WordPress auction theme is the most affordable route (a one-time license), dedicated auction software costs more for added power and scale, and fully custom development is the premium option. Your choice depends on how unique your bidding rules and integrations need to be.
Can I build a site like DealDash or Tophatter myself?
Yes. A penny-auction or lightning-auction site can be built with the right auction software or a WordPress theme that supports pay-to-bid and timed mechanics. Our auction software and custom development team can build either model for you.
