How D2C teams find out about competitor price cuts — before and after DiffScout:
Before: Manually checking 6 competitor tabs every Monday morning
Before: Sales team mentions a competitor's weekend flash sale — on Wednesday
After: Email lands at 9:42am: “Gymshark Vital Shorts £45 → £32 (–29%)”
After: Team responds before noon. Ad copy updated. Margins defended.
WHY TEAMS CHOOSE DIFFSCOUT
Stop opening tabs on Monday morning. DiffScout watches 24/7.
Visualping detects changes. DiffScout tracks prices.
Visualping tells you something changed on the page. DiffScout tells you the price went from $89 to $74 — and emails your team within the hour. Price-specific intelligence, not a screenshot diff.
Prisync is for 100+ SKUs. DiffScout works from any URL.
Prisync requires you to upload a catalog and match SKUs before monitoring starts. DiffScout works from a single URL — paste a competitor link, describe what to track, and you're live in 30 minutes.
Works on Shopify, Amazon, and any brand site.
Track competitor Shopify storefronts, Amazon listings, and D2C brand sites simultaneously — all in one place, no Shopify-only restrictions, no per-channel add-ons.
HOW WE COMPARE
Simpler than Prisync. Cheaper than Wiser. Built for D2C teams, not enterprise IT.

Common questions
How is DiffScout different from Prisync or Price2Spy?
Prisync and Price2Spy require you to build product catalogs and match SKUs before monitoring starts — which takes days and often needs developer help. DiffScout uses AI vision on screenshots, so you just paste a URL and monitoring begins immediately. No product matching, no integration, no setup complexity.
Does it work on Shopify stores?
Yes — DiffScout handles Shopify storefronts, brand direct sites, Amazon product pages, and marketplace listings. The AI vision stage works even on JavaScript-rendered product pages that traditional scrapers miss.
What counts as a check?
Each time DiffScout visits a URL to compare prices is one check. Checks run on your chosen schedule (every 30 min on Business, daily on Free) and only consume a check when the page is actually fetched.
What if the site blocks bots?
DiffScout tries multiple extraction methods automatically — from fast structured data reads to AI vision that analyzes a screenshot of the page the same way a human would. This layered approach means DiffScout succeeds on Shopify storefronts, heavily guarded brand sites, and JavaScript-rendered pages that traditional scrapers miss.
How accurate is the price extraction?
Very accurate — every extraction is validated and a screenshot is archived at each check so you can verify any result. You can also set alert thresholds (e.g. only alert when price drops by more than 5%) to avoid notifications on minor rounding changes.
Can I monitor multiple variants of the same product?
Yes. When scanning a product page, DiffScout detects all visible price variants (sizes, colors, tiers). You choose which ones to track — each variant can trigger its own alert.
Is there a free plan?
Yes — 1 monitor and 5 checks, no credit card needed. Enough to validate DiffScout works on your target pages before upgrading to Pro ($49/mo) or Business ($99/mo).
How long does setup take?
Most users are live in under 30 minutes: create an account, paste a competitor URL, describe what to track, scan, confirm the extracted price, and save. Your first email alert arrives on the next scheduled check.
