The eBay item tracker that watches every listing you care about.
Paste eBay item numbers and uBuyFirst follows each listing’s price, status, quantity and end time for you — up to 100,000 items, refreshed every 5–10 minutes through eBay’s official API. When something changes, it reaches you on Slack, Telegram, WhatsApp, Discord or email, instead of waiting for the next time you think to look.
eBay’s watch list tells you nothing until you open it.
It shows today’s price and whether the listing is still up. It doesn’t remember yesterday’s price, doesn’t show how many units are left, and doesn’t tell you when a seller quietly ends a listing and puts it back up at a different number while you’re busy with something else.
- No price history — you can’t tell whether a listing is drifting down or was always this price
- No quantity — a multi-unit listing down to its last unit looks exactly like one with forty
- Forty tabs open and refreshed by hand, and the one you wanted still sells while you’re on tab twelve
- eBay’s watch-list emails arrive on eBay’s schedule, for the few events eBay chooses
- Past a few dozen items it turns into a spreadsheet you maintain yourself
One grid, every change logged.
Paste the item numbers once. From then on uBuyFirst checks each listing on a schedule, records what changed and when, and tells you on the channel you already keep open.
- Price, status, quantity and end time for every item, with a timestamped change history
- Up to 100,000 items per account — sourcing lists, competitor catalogs, the parts you’re waiting on
- Told where you work: Slack, Telegram, WhatsApp, Discord or email, only for the events you pick
- Runs on eBay’s official API under uBuyFirst’s approved credentials — your eBay account isn’t touched
Want to catch new listings the moment they appear? That’s eBay alerts. Item Tracker is for listings you’ve already found.
Everything a listing can do, tracked.
Four things change on an eBay listing between the day you find it and the day it’s gone: the price, the status, the quantity and the end time. Item Tracker watches all four, keeps the history for every item, and lets you decide which changes are worth interrupting you for.
Price tracking Free in beta
Every price change is logged with a timestamp, so you can see whether a listing has been creeping down for weeks or just dropped for the first time — and buy on the trend, not on a single glance.
→ How it worksStatus tracking Free in beta
Active, out of stock, sold or ended. Know on the next check, not the next time you look, when a listing closes — and whether it actually sold or the seller simply ended it, two very different signals for what to do next.
→ How it worksQuantity tracking Free in beta
For multi-unit listings the tracker records how many are available, so you see stock running down, hitting zero and coming back — the back-in-stock moment the watch list never mentions.
→ How it worksEnd-time tracking Free in beta
Auctions and Good ‘Til Cancelled listings both have an end time, and it moves: an auction runs down to its deadline, a Good ‘Til Cancelled listing renews or gets ended early. The grid shows the current end time for every item and updates it whenever it changes.
→ How it worksBulk paste Free in beta
Paste up to 10,000 item numbers at a time, one per line, from a spreadsheet, a sourcing list or a competitor’s store. Track up to 100,000 items per account, then filter and sort the grid however you work.
→ How it worksTold where you work Free in beta
Pick the events — price drop, back in stock, out of stock, sold, ended — and the channels: email, Slack, Telegram, WhatsApp or Discord. Nothing else gets through.

Item Tracker is a module of the free uBuyAssist web app, the same app that runs eBay search and saved searches. It’s free while it’s in beta. If we ever charge for it, this page will say so first.
- Works on Mac and PC in the browser; nothing to install
- Item Tracker: paste item numbers, follow price, status, quantity and end time, keep the history
- Told on email, Slack, Telegram, WhatsApp or Discord — for the events you pick, on the channels you want
- Up to 100,000 tracked items per account, 10,000 per paste
- Filter and sort the grid; every item keeps its own change history
From a pasted list to a grid that keeps itself up to date.
Paste your item numbers
Open Item Tracker in the web app, click Add items, and paste eBay item IDs one per line — from a spreadsheet, a sourcing list, or the numbers in the listing URLs. Up to 10,000 in one go.
Wait for the first check
Each new item reads “Pending” until its first check lands. The first check can take longer than the steady-state cadence. After that, new items are checked on roughly a ten-minute cadence through eBay’s official API.
Read the grid
Status, current price, quantity, end time and when each item was last checked, plus a per-item change history. Filter and sort to find what moved.
Choose what interrupts you
Tick the events that matter — price drop, back in stock, out of stock, sold, ended — and the channels you want them on. Everything else waits in the grid for the next time you look.
Why buyers outgrow eBay’s watch list.
