Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBidly is a live auction app for Shopify that lets merchants sell products through real-time bidding. Merchants can create and manage auctions from an admin dashboard, while customers place bids directly on product pages or a dedicated auction marketplace. Bidly supports anti-snipe bidding, reserve prices, buy-now options, live chat, automated emails, and seamless winner order creation.
Hammerdown turns any product in your catalog into a timed auction, without moving your store anywhere else. Shoppers bid from the product page and watch every bid land in real time. Buyers can set a private maximum and let the app bid on their behalf. A bid in the closing seconds pushes the end time out, so an auction ends when the bidding does.
- Real-time bidding with popcorn anti-snipe extension
- Embedded widget on product pages with live bids & timer
- Dedicated customizable auction marketplace page
- Optional live chat per auction to build bidder excitement
- Real-time bidding on product pages, plus a live auction grid page
