AuctionMethod is white-label auction software built on a flat-fee model: no commissions, no per-lot fees, no platform skim, and no contract, so clients keep the revenue from every sale instead of splitting it with the platform. Since 2012, AuctionMethod has also offered custom auction software development for auction businesses whose workflows do not fit an off-the-shelf platform.
Based in Massachusetts, serving the U.S., Canada, Australia, and New Zealand, AuctionMethod works with auctioneers, estate liquidators, farm and heavy equipment, industrial, salvage and recycling, non-profit, corporations, retail liquidators, auto/car dealers, real estate, arts and collectibles, and single-use auction businesses. Clients keep 100% ownership of their bidder lists, seller lists, item data, images, and transaction history on a fully white-label auction website rather than a shared marketplace listing.
AuctionMethod has earned the SourceForge Spring 2026 Top Performer Award in Auction Software and is rated 4.9/5 on Capterra and SourceForge, with a 94% renewal rate. The platform handles catalog and lot management, consignor setup, bidder registration, invoicing, payment processing, tax handling, and reporting, and supports auction event types including timed online auctions, simulcast auctions, blind timed auctions, catalog-only, fixed-price, and perpetual events. For live, rapid-fire simulcast auctions, latency is critical: AuctionMethod specializes in real-time speed under one second so online bidders do not miss the auctioneer's hammer, running on infrastructure that is fully hosted with daily backups, auto-scaling for high traffic, and security updates included, with 100% uptime tracked on a public status page.
Pricing starts at $100/mo with a $250 one-time setup charge and is published publicly, with a 30-day free trial and no credit card required.

OpenSea is the largest online marketplace for trading crypto collectibles and non-fungible tokens (NFTs), featuring both ERC721 and ERC1155 asset types. Users have the opportunity to buy, sell, and discover a diverse array of unique digital items, including Axies, ENS names, CryptoKitties, and Decentraland assets. This platform is committed to fostering entirely new economies that revolve around true digital ownership. As both a pioneer and the foremost venue for user-owned digital items, OpenSea boasts a wide selection of products that range from collectibles and gaming assets to domain names and digital art, all of which are backed by blockchain technology. Our excitement at OpenSea stems from the rise of NFTs, a groundbreaking category of digital items characterized by their uniqueness, verifiable scarcity, liquidity, and cross-platform usability. Similar to their physical equivalents, you have the autonomy to manage these digital assets as you please—whether that involves discarding them, sharing them with friends across the globe, or listing them for sale on an open marketplace. In addition, unlike physical assets, these digital items are inherently programmable, giving rise to innovative applications. The adaptability and uniqueness of NFTs are transforming our understanding of ownership in the digital landscape, creating a new paradigm for how we engage with virtual assets. This shift not only enhances individual ownership experiences but also paves the way for collective digital economies.

Qliktag
Qliktag is a product digitalization and Web3 tokenization platform built to create secure connections between physical products and their digital identities. The system enables brands, manufacturers, designers, and creators to generate digital twins for individual physical items and assign each one a unique digital ID. Products can be tokenized on-chain or off-chain and connected to secure digital links that remain associated with the corresponding physical object. Qliktag uses secure NFC technology to help organizations create links that are difficult to clone and can be accessed when someone has the physical product in hand. Consumers can tap an embedded NFC tag to authenticate an item, access product details, verify ownership, or interact with digital content and services. The platform can maintain information about a product throughout its lifecycle, including ownership, location, service events, sustainability attributes, value, and other changing data. Organizations can configure digital product passports, traceability systems, circularity programs, returnable asset workflows, repair histories, and resale-related experiences. Blockchain capabilities allow physical products to be paired with NFTs and smart contracts for use cases involving ownership transfer, royalties, warranties, memberships, escrow, or gated digital access. A visual interaction designer helps teams create custom experiences around authenticated products without requiring every interaction to be developed manually. Qliktag is particularly relevant for luxury products, fashion, art, collectibles, sports memorabilia, fan merchandise, and other high-value goods where authenticity and provenance are important. By combining digital identities, NFC authentication, tokenization, lifecycle data, and consumer-facing experiences, Qliktag helps companies turn physical products into connected phygital assets.
