The problem
Following a product's price means going back to the shop again and again. And tools that only check while the browser is open miss many price drops.
Dropbeep.
Know the moment the price drops.
An extension and service that watches prices and stock in any online shop. It checks every hour from the server, even when your computer is switched off, and alerts you when a price drops or stock comes back.
- Checks while your computer is offChecks run every hour on the server, not in your browser.
- Alerts tailored to youTarget price, percentage drop or back in stock, by browser, email or Telegram.
- Price historyEach product keeps its price history, so you can tell whether an offer is really a good one.
The solution
The extension marks a product with one click and the server checks it every hour. When the price drops or stock returns, it alerts you by browser, email or Telegram. It has a free plan and paid plans.
Key decision
Separate the extension from the checking engine, so tracking carries on even when the computer is switched off. The engine is based on changedetection.io, an open-source project, adapted to prices and stock.
