This extension provides a local eBay auction sniping feature in a web browser.
It will automate bidding on your behalf just before the end of auction.

Unlike other sniper applications this extension doesn't need your eBay password so it won't be disclosed on any server.
All needed is an opened web browser tab with an active ebay session (this tab doesn't need to be visible).

PowerSniper comes with a free and a premium version.

Check out differences here.

Please stop posting negative reviews on Chrome store just because it is not a free extension.




  • Right click on extension icon, launch the tool.
  • Left click opens configuration panel.
  • Leave the tool open while sniping, with at least a part of its window visible.
  • See how to launch Powersniper at startup.


  • The displayed end time is calculated from remaining time grabbed from ebay site and is not accurate for actions lasting more than one day. Remaining time is periodically checked (see refresh period in advanced settings) and is getting precise only below 24h remain time lapse.
  • Important : activate 'sound trick' option or leave a part of the PowerSniper tab visible. More on Chrome throttling here.
  • Important : beware of eBay captchas!. Look here for details.
  • Do not launch several instances of PowerBuyer.
  • Note about support : due to many emails asking for support, I now have to prioritize answering toward registered user.
    In any case I will not answer to rude or cheeky emails.
  • Depending on your internet connection, avoid heavy network activity (like internet download, video preview ...), beware of Windows Update.
  • If you update settings through the browser toolbar button and Powersniper extension is opened, then you will need to refresh that page.
