Restock alerts that fire the second it's back in stock
PS5, Switch 2, Pokemon cards, Labubu, sneakers — the things you actually want sell out in minutes. DiffHook watches the product page for you and pings your Discord, email, or phone the instant it's available again.
No browser extension to leave running. No restock Discord to babysit. Set it once — we do the watching, 24/7, for free.
Why restocks are so hard to catch
The drop is over before you even see it
Anyone who has chased a restock knows the feeling: the item you want is out of stock for days, then it quietly comes back in stock at some random hour and sells out again in minutes. Retailers don't announce drops in advance, and resellers run bots that buy the second a page changes — so by the time you refresh, it's gone.
A restock alert flips that around. Instead of you watching the page, the page watches itself: DiffHook checks the exact product listing around the clock and pings you the instant it's back in stock. You stop refreshing dead tabs and start finding out first — the same moment the bots do, for free.
How it works
From sold out to checkout in three steps
Paste the product link
Drop in the URL of anything you want to watch — a Target listing, a Pop Mart drop, a sneaker page. Add as many as you like.
We watch it 24/7
DiffHook checks the page on a tight interval and watches for the stock status, price, or Add to cart button to change.
Get the instant alert
The moment it's back, you're pinged on Discord, email, Telegram, or a webhook — usually within seconds.

By store
"When does it restock?" — answered, and automated
No store publishes a real restock schedule. Pick a retailer to learn how its restocks work — then let DiffHook watch the exact page for you.
Why DiffHook
Built to beat the refresh button
Alerts in seconds, not minutes
The moment the page changes, you know. That's the same signal scalper bots watch — so you find out at the same time they do.
Runs in the cloud
No app open, no extension burning your battery, no computer that has to stay on. DiffHook watches even while you sleep.
Alert where you already are
Discord, email, Telegram, Slack, or your own webhook. Wire it into a Shortcut for a phone push if you want.
Watch the exact item
Not a whole category — the specific size, color, or variant you want. No noise, no false alarms.
