Price tracking

Price drop alerts for any product page

Point DiffBell at a product page and the price element. When the number changes, you get a diff showing the old price and the new one.

Phone push: install the free ntfy app (iOS/Android) and subscribe to the same topic name you type here. Pick something hard to guess.

No password. Free for 5 pages. We'll check right away and save a baseline.

Works beyond the big marketplaces

Most price trackers only cover a few big retailers. DiffBell reads any public page: boutique shops, airline fare pages, hotel rates, SaaS pricing pages.

Use a selector to cut noise

Open the page, right-click the price, choose Inspect, and copy its class or id (for example .price). Paste it into the CSS selector field so DiffBell ignores everything else on the page.
