Stop Checking. Start Winning.
Manually checking for restocks is a losing game. Guppy watches the page in the background so you can get back to your life.
- Target & Wait: Paste the product URL and set your price or restock trigger.
- Acts Instantly: Because Guppy runs locally in your browser, it reacts the moment the page changes.
- Hands-Free Execution: Get notified, or let Guppy auto-cart and attempt checkout the second the button goes green.
Early access feature - requires browser to remain open.
Turn "In Line" to "In Cart."
The hardest part of a drop is the panic when you finally get through the queue.
- Queue Co-Pilot: Enable Auto-Checkout while you wait in line.
- Instant Reaction: The moment you enter the store, Guppy attempts to secure the item faster than you can click.
- Built for Speed: Designed to handle the "Action Needed" moments so you don't fumble.
Early access feature - we recommend keeping an eye on your tab while it runs.
