Overview
DIFFSCOUT is a price monitoring service built for D2C brands, e-commerce operators, and growth teams. You give it a URL and describe what to track; it checks the page on a schedule and emails you when the price changes.
No code, no spreadsheets, no browser tabs left open.
How it works
- Add a monitor — paste a competitor's product URL and describe the item (e.g. "Vital Seamless Shorts Medium Black").
- Preview extraction — DIFFSCOUT scans the page and shows you all detected prices before you commit.
- Set a schedule — choose how often to check: every 30 minutes (Business), hourly (Pro), daily, or weekly.
- Get alerted — receive an email (or webhook POST) the moment a price changes.
What DIFFSCOUT monitors
- D2C brand sites — Gymshark, Alphalete, SKIMS, Allbirds, Lululemon, etc.
- Shopify storefronts — product pages, collections, variant pricing
- Amazon product detail pages — one-time purchase price, variant prices
- Any publicly visible pricing page
ℹ Note
DIFFSCOUT cannot monitor pages behind a login. Only publicly accessible URLs are supported.
