A live auction gives you 20 seconds to decide.

The seller holds the item up, the chat starts hyping, and the price climbs $5 at a time. By the time you've opened a new tab, typed the title into eBay, and switched the filter to Sold Items, the lot is gone — or you've paid 40% over what it's worth.

That's the whole problem. Not a lack of data — eBay has decades of it. A lack of time.

Comps most buyers actually check mid-stream

Everything you need to bid with a number in your head

CompLive does one job and does it fast: turn the item on screen into real sold data.

Comps in under a second

Hit scan and the median sold price, range, and latest sales land on screen before the bidding heats up.

Any category, not just cards

Watches, sneakers, comics, toys, tools, vintage clothing — if it sold on eBay, CompLive finds it.

Auto-detect new items

Pro watches the stream for the next lot and pulls fresh comps the moment the item changes.

Know your walk-away number

A hard price range keeps you from chasing a $180 item to $260 because the chat got loud.

Scan history

Every lot you scanned, saved with the comp data — review what you won and what you dodged.

Stays out of the way

A small draggable panel you can collapse. No autoplay noise, no bidding on your behalf, ever.

The overlay, on the stream, where you're already looking

  • Median sold price

    The single number that tells you whether the current bid is a deal.

  • Recent sales with dates

    Because a comp from 2021 is not a comp. Freshness is shown per sale.

  • Full eBay sold search, one click

Placeholder review · Reseller
"Paid for itself the first night. I passed on two lots that were going way over comps."
