Bidwatcher is a free auction tool for eBay users, available for Linux and (soon?) Microsoft Windows. It was created by Trent and Tom McNair, and is currently maintained by volunteers at SourceForge.


  • Tracks your eBay listings and items that you have bid on.
  • Allows you to track auctions that you do not own and have not bid on.
  • Snipe tool allows you to schedule your bid to be placed seconds before the auction ends, avoiding driving the price high early in the auction's life.
  • Prioritizes updates according to the time left in an auction. (i.e. updates auctions that are almost over more often than ones that have a while to go).
  • Clock on main window synchronized to eBay time.
  • Runs in the background with minimal toll on system resources.
  • It's free!

Who is this for?

If you regularly list/purchase items at eBay, you might find Bidwatcher useful for keeping track of your auctions. To use it, just plug in your eBay username and Bidwatcher does the rest. It checks eBay on a regular basis for your new auctions and deletes auctions as they end. You can bid on items on the fly, or set up a 'snipe' - an automatic bid that takes place a short time before the end of an auction. Bidwatcher saves all your settings and static auction information when you close it, so you can launch it whenever you need an update, or you can leave it running in the background and let it continually update your auctions.
