Get alerted the moment a competitor changes their price.
DiffScout monitors any pricing page and sends an instant alert when a price moves — with the exact old value, new value, and % change. No more manual checking.
This is what a price change alert looks like.
Within ~1.8 hours of a competitor price change, this lands in your inbox — or your Slack channel on Business.
Where alerts are delivered
Every alert includes the same data — mission name, old price, new price, % change, and timestamp — regardless of channel.
Includes old price, new price, % change, timestamp, and a direct link to the price history chart. Arrives in your inbox on every check cycle that detects a change.
Delivered to a channel of your choice. Shows the same data inline — no separate email needed. Set up via webhook URL; no Slack app install required.
Fire to any endpoint: Zapier, Make, PagerDuty, or custom code. JSON payload with full change data — mission ID, URL, old price, new price, % change, timestamp.
When does an alert fire?
DiffScout is built to eliminate noise. You only hear about real price changes.
What teams use price change alerts for
From flash sale detection to MAP enforcement — if a number on a webpage matters, DiffScout can watch it.
Your competitor starts a 20% sitewide flash sale at 8am Friday. You get an alert by 9:30am. Your marketing team has time to respond before the weekend traffic peak.
A retailer drops a product below MAP on Wednesday morning. You get an alert the same day — not at the next weekly review when the damage is already done.
A competitor quietly lowers their Pro plan from $99 to $79. You catch it before your sales team hears it from a prospect mid-deal. Respond on your terms.
Track an ASIN. Get alerted when the Buy Box price drops, triggering a pricing response before organic ranking begins to erode or conversion takes a hit.
