Sour Sync Atlas · Now Live

Know what your competitors charge.
Before your buyers do.

Atlas monitors Back Market, Swappa, eBay, and Reebelo — plus any custom competitor URL — so you're never the last to know about a price drop.

How Atlas works

From subscription to live price intelligence in minutes

Step 1

Curated sources, zero setup

Back Market, Swappa, eBay, and Reebelo are already connected. The moment you subscribe to Atlas, Sour Sync starts collecting price data across all four — no configuration required.

Step 2

Add any competitor URL

Paste any competitor's website. Atlas parses their sitemap, finds every product page, and starts tracking prices immediately. Set your refresh frequency — from daily to hourly.

Step 3

Price matrix + 30-day trends

A live grid of device model × condition × platform prices. See exactly where you're underpriced, overpriced, or right on the market. Trend charts show movement over 30 days.

Custom competitor URL pricing

Curated sources are included free on every paid plan. Custom URLs are billed per crawl based on page count and site difficulty.

Estimate your Atlas crawl cost

Curated sources (Back Market, Reebelo, Gazelle, GoReCell, and more) are included free on every paid plan. Use this calculator to estimate cost for adding your own competitor URLs.

Everything in Atlas

4 platforms, zero setup

Back Market, Swappa, eBay, and Reebelo are curated and maintained by Sour Sync. Subscribe and the data is already there.

Custom competitor tracking

Any URL. Any catalog size. Atlas parses the sitemap, crawls each product page, and extracts prices — no HTML knowledge required.

30-day price history

Every snapshot is stored. See how competitor prices have moved over the past month — catch seasonal trends before they hit your margins.

Device × condition matrix

Prices broken down by device model and grade (A/B/C or Excellent/Good/Fair). Know exactly what a Grade B iPhone 14 128GB sells for across all platforms.

Credits, not flat fees

Curated sources are included in your subscription. Custom crawls use your credit balance — you only pay for the scans you actually run.

Frequency you control

Set each custom source to daily, twice daily, every 6 hours, or hourly. You decide the refresh rate — and the credit spend — for every competitor.

Premium IMEI rate card

Premium IMEI checks — pay as you go

Device identification and reverse IMEI search — model, manufacturer, and carrier — are free and unlimited on every plan. The premium checks below are pay-as-you-go, billed monthly on your subscription invoice.
