The short answer: use eBay's own saved searches for simplicity, SearchDome for scheduled email alerts with US ZIP-distance filters, Item Alert for fast browser-tab monitoring, or AuctionMapper Hunt for collected on-site matches with price-and-shipping controls. None wins every column.
Run a focused category search first, then decide whether a native saved search, Hunt, or another alert workflow fits the job.
“Alert tool” covers at least three different jobs: a native reminder inside eBay, a server that emails when it finds a new listing, and a monitor that collects matches for later review. Polling speed matters to a buyer chasing a fast-selling item, but a local-pickup hunter may care more about ZIP radius and an all-in budget.
The table therefore separates timing, delivery, price filters, distance, landed cost, and item-specific filters. When an official or reviewed source did not establish a feature, the cell says so instead of turning missing evidence into a “No.”
This is a dated feature check, not a permanent guarantee. Tool owners can change pricing, limits, and availability.
| Tool | Check timing | Delivery | Category and item price | ZIP distance | Landed-cost cap | Aspect filters | Access and cost |
|---|---|---|---|---|---|---|---|
| eBay Saved Searches | eBay does not promise a cadence on its help page; Item Alert's FAQ describes eBay delivery as once daily. | Email, Saved feed, and configurable saved-search notifications. | A saved query can retain filters; eBay documents price, color, and listing type as examples. | Not established in reviewed evidence. | Not established in reviewed evidence. | Some saved filters are documented (for example, color); broader coverage is not established. | Included with an eBay account. |
| SearchDome | Server-run schedules: free 10- or 15-minute, hourly, or daily options; paid 1-, 2-, or 5-minute options. | Email and an on-site search dashboard. | Category selection plus minimum and maximum item-price filters. | Yes — radius around a US ZIP code. | Not established in reviewed evidence. | Not established in reviewed evidence. | Most features are free; faster 1-, 2-, and 5-minute checks use paid credits. |
| Item Alert | Reports 20-second checks while its search page remains active; browsers may throttle background tabs. | Audio cue, email, or automatically opened result tabs. | Price ranges and listing-format searches are documented; category support was not established. | Not established in reviewed evidence. | Not established in reviewed evidence. | Not established in reviewed evidence. | Free account; its FAQ said new registration was disabled when checked July 30, 2026. |
| AuctionMapper Hunt | Scheduled server-side monitoring; AuctionMapper does not make a public speed promise. | Matches collect in My Hunts, with an optional daily match-summary email linking to the dashboard when email delivery is available. | Keywords, condition, format, and item-price band; a numeric category and available aspects can be carried over from an AuctionMapper search. | ZIP/radius works in the immediate search path; exact distance is not enforced by current background monitoring. | Partial — monitoring can prefilter an item-plus-shipping estimate, before tax. | Category and aspect filters can be carried from a search; the standalone builder has no aspect picker. | Free; device-only saving needs no account, while monitoring uses email sign-in. |
Choose the native option when you already use eBay, want to retain a normal filtered search, and do not need a documented rapid-check interval. eBay's help says new matching listings can trigger email and that searches also appear in your Saved feed.
eBay also documents editing saved filters such as price, color, and listing type. Its help page does not promise how quickly every match produces an alert.
Read eBay's saved-search helpSearchDome is the strongest documented fit here for a buyer who wants server-run email alerts and a specific radius around a US ZIP. Its current form also exposes category, item-price, condition, format, shipping, and seller controls.
Its official pages list free 10- and 15-minute schedules and optional paid 1-, 2-, and 5-minute checks. That means AuctionMapper does not claim distance-alert exclusivity.
Inspect SearchDome's current search formItem Alert is the speed-oriented option in this comparison. Its FAQ reports checks every 20 seconds and delivery through audio, email, or automatically opened listing tabs.
The tradeoff is important: the search must keep running in a browser tab, background throttling can slow it, and the same FAQ said registration was closed because of an eBay API limit when checked July 30, 2026.
Read Item Alert's current FAQHunt is for a buyer who would rather collect new matches on-site than receive listing emails. The current monitor combines keyword, condition, buying format, item-price band, and an item-plus-shipping ceiling, then lets the user pause, renew, or delete the hunt.
It is not the speed pick. Its current broad department field is not an exact eBay category filter, its monitored landed-cost check is an estimate before tax, and exact ZIP distance is not enforced by background match collection.
Build an AuctionMapper HuntStart with eBay Saved Searches.
It is native, familiar, and keeps ordinary eBay filters without another service.
Compare SearchDome first.
Its documented server schedules and email delivery do not require a browser tab to stay open.
SearchDome has the clearest alert fit.
It explicitly combines server-run alerts with distance from a US ZIP. AuctionMapper can apply ZIP radius in its immediate search, but not yet in background monitoring.
Item Alert reports the fastest free checks here.
Its FAQ says 20 seconds, but only while the browser search stays active, and new registration was closed at the review date.
AuctionMapper Hunt may fit.
It collects matches in a dashboard and can combine condition, format, item price, and estimated item-plus-shipping limits.
AuctionMapper can carry filters from your search.
Carry a numeric category and available aspect filters from an AuctionMapper search into Hunt. The standalone builder has no aspect picker; broader aspect support was not established for the other reviewed tools.
It depends on the job. Use eBay Saved Searches for the lowest-friction native option, SearchDome for scheduled server-side email plus US ZIP distance, Item Alert for fast in-browser checks if you already have access, or AuctionMapper Hunt for on-site collection with condition, format, price, and estimated item-plus-shipping filters.
eBay's official help says it emails when new matching items are listed, but it does not state an exact cadence. Item Alert describes the cadence as once every 24 hours. That makes the daily figure a competitor-reported observation, not an eBay guarantee.
SearchDome explicitly supports a mileage radius around a US ZIP. AuctionMapper's Hunt builder captures ZIP and radius for the immediate search path, but the current background monitor does not enforce exact distance. No distance conclusion was established for the other rows.
No, according to its FAQ checked July 30, 2026. The search must remain running in a browser tab, and background-tab throttling can slow its reported 20-second refresh rate.
Hunt offers a daily match-summary email option when delivery is available. Open the listings in My Hunts. The summary links to this dashboard; it does not include individual listing links.
Competitor behavior in this guide comes from the official pages below, checked July 30, 2026. AuctionMapper Hunt behavior was checked against the current Hunt builder, monitor, poller, and My Hunts implementation—not inferred from older marketing copy. “Not established in reviewed evidence” means exactly that; it does not prove a feature is absent.
