Who Watches the Watchlist — eBay Watchlist Price Tracker & Alerts

eBay watchlist price tracker. Monitor prices, get price-drop alerts, see price history. Free, private. Stays on your device.

This project started because I'm an eBay super user and noticed that prices on my watchlist seemed to change over time without me being able to confirm. I was always asking questions: • Is this item at its best price or its highest price? • Did the seller increase the price and then immediately drop it to show a discount that isn't a real discount? • Is an item slowly decreasing over time and I should wait until it hits a target? With Who Watches the Watchlist now you can know for sure! I'm a solo developer who uses this extension every day for myself so it is always being refined. Feedback and bug reports are greatly appreciated and will be responded to. eBay is one of the great holdovers from the early internet but how do you know when an item on your watchlist hits the price you want? Who Watches the Watchlist records the price of every item on your eBay watchlist and tells you when one moves. How to use Who Watches the Watchlist Sign in to eBay in this browser, install the extension, and you're done. There is nothing extra to sign up for. A few times a day it checks your watchlist in the background using the eBay account you're already signed into and writes down each item's current price. You can change the schedule or press Refresh now any time from the dashboard. When an item you've set an alert on crosses your threshold, you get a desktop notification. No personal data from your watchlist leaves your computer. No separate accounts. The only data the extension sends out are anonymous install / session-start / uninstall counters to Google Analytics so we know the extension is being used — no item data, prices, or watchlist content is included in those counters. (Like any web request, the connection to Google does expose your IP address and User-Agent at the network layer — see PRIVACY.md for the full disclosure.) Otherwise the only thing the extension loads from the internet is your own eBay watchlist page. Earning a commission (on by default, one-click opt-out). When you click an item from inside the extension to view it on eBay, the click goes through eBay's affiliate program with our partner ID — so if you happen to buy that item within 24 hours, eBay pays us a small commission. The price you pay does not change. We receive only aggregate click and purchase counts from eBay, never your personal information. You can turn this off any time from the dashboard's settings. What it does • Builds a price history for every active item on your eBay watchlist • Per-item charts on the dashboard, with all-time low / high / average and a clear summary of whether the price actually moved or just bounced and came back • Price-change notifications you configure per item — set a dollar threshold, a percent threshold, or both, and choose increase / decrease / either direction • Target price alerts — get notified the moment an item drops below (or rises above) a price you name • Set alerts without leaving the popup — click the bell next to any item and a small panel opens right there, with a one-line summary of what will actually fire • A master notifications switch to silence everything (e.g. while away) • Auctions are tracked too (the current bid) • Search and sort your tracked items (recently added, price, name) • One-click CSV export of the full per-item summary • Remove an item from your eBay watchlist right from the popup or dashboard (trash icon, with a confirm step) • Write, edit, or clear an item's "Note to self" on eBay from the item's view; notes also show under the item title in the dashboard and popup • Optional (off by default): write a short price log into an item's "Note to self" on eBay, so the price history travels with the item — only for items that don't already have a note How it works (the important bit) The extension only checks prices while Chrome is running. If Chrome is fully closed for a while you'll see a gap in the history — it resumes automatically next time you open Chrome. Checks are scheduled (default every 4 hours; configurable) and you can also press "Refresh now" any time. You must be signed in to eBay in the same browser.
