Live auction software that keeps every bidder in the room
Whether you're running a live webcast from your auction room or a fully automated timed sale, BidJS by Bidlogix delivers real-time bidding on your own website — under your brand, with your bidder data, and no commission on sales.
What is live auction software?
Live auction software enables auction houses to conduct sales in real time over the internet — either as webcast auctions (where floor, phone, and internet bids compete simultaneously) or as timed online auctions (where lots close at preset times with automated bidding). BidJS supports both formats, with the same real-time WebSocket infrastructure powering every bid.
Why sub-50ms bid broadcasting matters
In a live auction, every millisecond matters. Bidders who see a stale price or a delayed notification lose trust in the platform — and the auction house. Our WebSocket infrastructure broadcasts bid updates to connected bidders in under 50 milliseconds. Our broadcaster architecture supports up to 40,000 concurrent connections per regional stack.
Your brand, not ours
Unlike shared marketplace platforms, BidJS embeds directly into your existing website. Your bidders see your domain, your branding, and your logo — not a third-party marketplace. Every bidder who registers is your customer, and their data belongs to you. There is no commission on sales: your hammer price and buyer's premium stay entirely with your auction house.
