Always watching eBay

Find it before someone else does.

Tell Spotter Otter exactly what you want. It checks eBay for new matching listings and alerts you so you don't have to keep searching manually.

Less searching. Fewer junk alerts.

Spotter Otter isn't just an eBay search box. It remembers what it has already seen, separates new listings from old ones, and lets you narrow results without repeatedly rebuilding searches yourself.

New-listing detection

Seen listing IDs are remembered so the same item doesn't look new every time a check runs.

Useful filters

Price, condition, listing type, free shipping, ZIP-aware delivery and local pickup radius.

Cleaner keywords

Require words that matter and block words that create irrelevant results.

Fast handoff

Alerts show the listing details and send you directly to eBay to decide whether to buy.

Your watchlist

Everything Spotter is watching.

Pause a search, edit its criteria, check it immediately, or open the latest matches without recreating anything.

How it works

Set it once. Let the otter watch.

1

Describe the item

Enter normal search terms, a price ceiling, and any filters that actually matter to you.

2

Spotter checks eBay

The backend queries eBay's official Browse API and compares the results with listings already seen.

3

You get the match

When a new qualifying listing appears, Spotter sends the details and a direct eBay link.
