Auction Countdown

Auction Countdown — Synced Bidding Deadline For Every Bidder

A live auction or limited drop lives or dies on everyone seeing the same deadline. Share this link before bidding opens and every bidder's screen counts down to the identical closing second — no one can claim their clock ran differently.

Common questions

Can every bidder trust they're seeing the same closing time?

Yes — every device counts down to the exact same shared deadline encoded in the link, so no bidder's clock can legitimately run ahead of or behind anyone else's.

Is there a limit on how many bidders can watch the countdown?

No — any number of people can open the same link at once, since each device just does its own math rather than connecting to a server.

What happens the instant bidding closes?

Every open screen reaches zero at the same instant and shows the countdown has ended — treat that as your hard cutoff for accepting further bids.
