How is this different from Keepa or CamelCamelCamel?

Keepa and CamelCamelCamel are read-only Amazon price-history charts for shoppers. DiffScout sends an alert email or Slack message the moment a price moves on the listings you watch. We also work outside Amazon: track the same SKU on brand.com, Walmart, Target, Best Buy in one feed, so you see which retailer breaks first.

Does it support MAP enforcement workflows?

MAP enforcement is on our 2026 roadmap — today, DiffScout catches the underlying signal (Buy Box flip below your price floor, with seller name, timestamp, and screenshot). Your team files the Brand Registry violation manually for now. The auto-packaged violation-report workflow is coming. Email us if MAP is your primary use case so we can prioritize the build.

Can I track Amazon Buy Box rotation in near-real-time?

Yes. The Pro plan checks hourly, the Business plan every 30 minutes. Track each ASIN you compete with, each ASIN you sell, and every authorized reseller listing — when the Buy Box flips to a new seller at a new price, you see it within the hour.

Does it work alongside our existing Amazon repricer?

Yes. DiffScout doesn't reprice anything. We're the detection layer; the repricer (Sellerboard, Aura, RepricerExpress) is the response layer. DiffScout sees the Buy Box flip happen, alerts your team, the repricer reacts.

How much after the trial?

14-day free Pro trial with full Pro limits, no credit card. Auto-drops to a real Free plan (1 mission, 30 checks/month, 7-day history). Pro is $49/mo for 50 monitors and 200 checks; Business is $99/mo for unlimited monitors, 30-minute scheduling, webhook + API alerts.

Is monitoring a competitor's public pricing page legal?

Yes. DiffScout reads only the public price elements on URLs you paste — the same data a human visiting the page sees. We don't bypass paywalls, scrape login-only data, or store anything beyond the price, timestamp, and a public screenshot. We also respect robots.txt directives. Tracking publicly listed prices on competitor product pages, Amazon listings, and SaaS pricing pages is standard competitive intelligence and is legal in the US, UK, EU, Canada, and Australia. Procurement teams can route this answer through legal if helpful.

[ What lands in your inbox ]

The alert tells you what to do, not just what happened.

Old price, new price, percent change, the seller currently winning the Buy Box, the timestamp, a 7-day price history, and a screenshot of the page at the moment it changed. No chart to decode. No team Slack to scroll. The email is the action.

Caught a $40 Buy Box drop on AG1 within 90 minutes.

A 3P seller flipped the AG1 Buy Box from $79 to $39 — a $40 list-price drop on a hero ASIN. DiffScout pinged Marcus at 11:14am. By 11:40 he had a counter-offer queued for his Subscribe-and-Save customers. Estimated $34K in retained subscription revenue from one alert.

Spotted a SaaS tier reshuffle 4 hours before the announcement blog post.

A major B2B competitor moved SSO from their $12 tier to their $28 tier on a Tuesday — quietly, no announcement. DiffScout's diff alert showed exactly which row changed. Aisha published a comparison post by lunch. 290 trial signups in 6 weeks; 4.5% conversion rate.

[ How it works ]

Sixty seconds from URL paste to first alert.

01
Paste a competitor URL.
Any product page, pricing page, Amazon ASIN, Shopify storefront, or B2B SaaS plan page. The 5-method extraction waterfall reads structured data first, falls through to AI vision when a site blocks scrapers.
02
Pick the SKU you actually compete with.
Variants (sizes, colors, bundles) are detected automatically on a single scan. You track the variant that matters, not the URL.
03
Get the email when the number moves.
Old price, new price, percent change, timestamp, and a screenshot. Daily on Free, hourly on Pro, every 30 minutes on Business.
