Get Instant Alerts When E-commerce Prices Change
Get instant alerts when product prices change on any e-commerce site. WatchDiff monitors prices automatically with AI-powered detection.
Price changes on e-commerce sites can happen without warning, affecting your competitive position and profit margins. WatchDiff monitors product pages across any online store and alerts you the moment a price shifts.
Unlike basic price trackers that only check specific fields, WatchDiff uses AI to understand the full context of a page. It catches price changes whether they appear in the main listing, bulk pricing tables, or promotional banners.
Set your preferred check frequency from hourly to weekly depending on how volatile your market is. Every detected change comes with a clear before-and-after comparison so you can act quickly.
WatchDiff integrates with your workflow through email alerts and webhooks. Connect it to Slack, your pricing engine, or any tool that accepts webhooks to automate your response to competitor price moves.
