Zero Hour places your bid in an eBay auction's closing seconds, even when you're sleeping or at work. Unlimited auction wins, even on the free tier. Unlike other services, we never see your eBay login credentials.
Works in Chrome, Edge, Brave, Opera, and Vivaldi.
Free download from the Chrome Web Store. Also works in Edge, Brave, Opera, and Vivaldi. No signup. If you're already signed into eBay in your browser, you're ready to snipe.
Our button appears on every eBay auction page. Pick a max bid and walk away.
The Zero Hour browser extension opens a background tab and makes your bid for you, even if you're fast asleep. Read the set up guide.
Zero Hour is the only eBay sniper that doesn't need to store your eBay login details, whose free tier has no monthly win cap, displays no ads, and needs no signup to use. All figures verified against each provider's published terms as of 2026-05-20. If anything is out of date, tell us.

Because your browser does the bidding, a couple of practical things only your machine can give us. Both take seconds to set up.
Two clicks on Mac or Windows stops the computer sleeping while letting the display sleep. The setup page walks through it with screenshots.
If you close your browser before the auction ends, Zero Hour can't fire the bid. Leave the browser running until close, that's it.
If you aren't logged into eBay in your browser, bids can't be placed. Make sure you are still logged in in the days preceding the auction end time.
"Sniping is permitted by eBay and is not forbidden by its rules. eBay's official position is that the practice does not violate any of the site's policies."
In 2002 a Berlin court explicitly struck down eBay Germany's brief attempt to ban sniping. The practice has been protected legally and in policy ever since. Zero Hour places a standard bid through eBay's standard endpoint, at the moment that gives you the best chance to win.
Yes. eBay's own terms permit last-second bidding. Wikipedia summarises it directly: 'Sniping is permitted by eBay and is not forbidden by its rules.' Several eBay-affiliated sniping services exist that would not be possible if sniping were against the rules. Zero Hour places a normal bid through eBay, just in the closing seconds rather than days before.
No. Zero Hour has no password field anywhere in the extension. Bids fire from your own browser using your existing eBay session, the same session that keeps you logged into eBay when you open ebay.com in a new tab. We don't ask for credentials because we don't need them.
Every other sniper is a server-side service. You give them your eBay username and password, and their server signs into your account and places the bid for you. Zero Hour runs entirely on your machine. There is no Zero Hour server that ever talks to eBay. Your password never leaves your computer because it was never asked for in the first place.
Yes. Your browser needs to be running and your computer awake when the snipe fires. Setting that up takes about 30 seconds. See setup for the exact two clicks on macOS and Windows.
The snipe fails with status 'auth_required' and you get a Chrome notification telling you to sign back into eBay. As long as you've used eBay in the same browser in the last few weeks, the session usually stays valid. Re-signing in is a one-tab job, and existing snipes resume immediately.
There is nothing in the bid request that looks different from a normal manual bid placed seconds before close, because it is one. Zero Hour does not spoof, evade, or automate anything beyond the timing of your bid. eBay's own bidding infrastructure handles the rest.
One active snipe at a time, but you can win as many of those snipes as you like. There is no monthly win cap, no ads, no signup, and we never ask for your eBay password, so your eBay account is at no additional risk from using Zero Hour. Most users discover they're sniping multiple auctions at once within a week. That's when Pro pays for itself.
Two options. $2.95 a month, cancel any time. Or $49 once for lifetime with no renewals and no expiry. Both unlock unlimited active snipes. We use Stripe Checkout; no card data ever touches Zero Hour. Stripe collects an email at checkout, and Pro is tied to that email: type it into your Zero Hour browser extension to activate.
Yes. Open Zero Hour on the new browser, tap the Upgrade button, choose 'Already paid? Activate with your email,' and type the email you used at Stripe checkout. Pro moves to that install. Pro is one install at a time, so the previous install drops back to free.
Because privacy claims are worth what they can be verified against. Right-click the Zero Hour icon, choose Inspect popup, open Sources, and you'll read the actual JavaScript running on your machine. Not a minified blob, not a separately published mirror that could drift from what's installed. This is rare in browser extensions. We think it should be the standard.
Yes. Zero Hour supports ebay.com, ebay.co.uk, ebay.com.au, ebay.de, ebay.fr, ebay.ca, ebay.it, and ebay.es. The extension uses each region's bid flow.
No. The extension does not embed any analytics SDK or tracking pixel. The only request it makes to our servers is there for Pro users to ensure they get their benefits. The marketing site uses Vercel Web Analytics, which is cookieless and aggregated.
Nothing. Your snipes live in chrome.storage.local on your own machine. If we vanish tomorrow, your last 100 won-auction records stay on your computer. There is no Zero Hour cloud to lose.
The extension is free. Twelve seconds to install, and you'll maximise your chances of snagging the best prices on eBay auctions.
