When a supplier runs out of a component or a competitor's best seller goes out of stock, the business that hears first gets to act first. WebsiteChange provides stock availability monitoring on public product pages: it extracts the stock status and the price, keeps a dated history of both, and alerts your buying or selling team the moment either one changes.
Availability matters on both sides of a trade.
Buyers watch supplier product pages for parts, materials and equipment they reorder. An item moving to "backordered" or "ships in 6 weeks" is a reason to place an order early, switch to an alternative supplier, or warn production planning before it becomes a shortage.
Sellers watch competitor product pages for the items they compete on. When a competitor goes out of stock on a key product, demand shifts, and a seller may adjust advertising or pricing. When the competitor is back in stock, that window closes.
This is a business tool for teams with a commercial reason to watch availability. It is not built for personal restock alerts.
On Growth, Business and Enterprise, WebsiteChange reads the price and stock status from a product page as separate values instead of a block of text. That makes changes precise.
Each check renders the page the way a browser does, so availability that a script loads after the page opens is still captured. If a product page has several variants, watch the variant URL or select the element that shows the variant you buy or sell.
The two events that matter most get their own treatment.
Route instant alerts to Slack, Microsoft Teams or email, and send the rest as a daily digest. Teams that keep stock data in their own systems use a webhook, which delivers each change with the extracted values. More on channels at website change alert.
For the price side in more depth, see competitor price monitoring and price monitoring software.
Every version keeps a full-page screenshot, the text and the extracted values. When a supplier review comes up, you can show how often an item was unavailable during the quarter and when each gap started and ended. Screenshots also show what a buyer actually saw on the page at that moment, which settles questions about stated lead times. History works the same way as in our website archive tools.
We read only publicly reachable product pages, respect robots.txt, and space requests per host. We never log in to a supplier portal on your behalf, never solve CAPTCHAs and never bypass access controls, so prices and stock shown only to logged-in trade accounts cannot be monitored.
