React to price drops and stockouts before your competitors do. Real-time alerts on any product page, anywhere.
The challenge
Prices and inventory change constantly across the web — and the teams that react fastest win. Manual checking doesn't scale past a handful of products.
How it works
Use a CSS selector to isolate the exact price element — `#corePriceDisplay`, `.product-price` — so irrelevant page changes don't trigger noise.
Price monitoring often needs 5–15 minute intervals to catch flash sales and time-limited offers before they expire.
Route the change event to a Slack alert, a repricing workflow, a buy trigger, or an email notification.
Use cases
Monitor competitor product pages and trigger your repricing workflow automatically when they change prices.
Watch out-of-stock pages and get notified the moment a high-demand product comes back into inventory.
Catch time-limited promotions on competitor sites within minutes — not hours — with 5-minute polling.
Build a full price history database by logging every detected change to Airtable, Sheets, or your own DB.
