Monitor Product Availability in Real Time
Track product stock status and availability changes on any website. Get alerts when items go in or out of stock with AI-powered monitoring.
Product availability changes constantly on e-commerce sites. Items go out of stock, get restocked, or have their availability restricted by region. WatchDiff monitors these changes so you never miss a critical stock movement.
Track availability across competitor stores, supplier catalogs, or marketplace listings. The AI engine detects status changes like out of stock, back in stock, limited availability, and pre-order transitions.
For procurement teams, knowing when a supplier restocks a critical component can mean the difference between meeting and missing production deadlines. WatchDiff provides the early warning system you need.
For competitive intelligence, tracking when competitors run out of stock on key products reveals demand patterns and supply chain vulnerabilities. Use this data to time your own promotions and inventory decisions.

Frequently Asked Questions
How quickly does WatchDiff detect stock changes?
Detection speed depends on your check frequency setting. With hourly monitoring, you will know about availability changes within an hour. For time-sensitive products, hourly checks on the Pro or Business plan are recommended.
Can WatchDiff distinguish between out of stock and discontinued?
WatchDiff reports the visible page content changes. If a product page shows out of stock versus discontinued or removed entirely, the AI change report will capture and explain the difference.
Does this work for monitoring my own product availability?
Absolutely. Many users monitor their own e-commerce listings to verify that availability displays correctly across channels. It serves as an external QA check for your own storefront.
