Research any Amazon product in seconds — without leaving the page.
SellerBeam is a Chrome extension that pulls live data from Amazon's Selling Partner API directly into a sidebar while you browse. Know your margins, eligibility, and competition before you make a single purchase.
Everything you need to source smarter
Three core tools, all loaded the moment you open an Amazon product page — no copying ASINs, no switching tabs.
Alerts
Know the risks before you commit to a product.
- Gated / Ungated
Instantly checks if your seller account can list this product. If gated, shows the exact approval reasons from Amazon.
- Amazon on Listing
Flags whether Amazon itself is competing. Amazon as a seller kills your Buy Box chances.
- Private Label Detection
Detects if the product is likely a private label with a clear warning and explanation.
Profit Calculator
Know your numbers instantly, before you buy.
- Live Sale Price
Auto-filled from the page, fully editable.
- Total Fees
Expandable breakdown: Referral Fee, FBA Fulfillment Fee, and Storage Fee from real product dimensions.
- Amazon Payout
What you actually receive after all fees are deducted.
- Net Profit, ROI & Margin
Enter your sourcing cost and instantly see profit ($), ROI (%), and margin (%).
- Keepa Integration
Click the chart icon next to Sale Price to open the Keepa price history chart for that ASIN.
Market Stats
Understand the competitive landscape instantly.
- Best Sellers Rank (BSR)
Pulled live from the SP-API — always accurate, never stale.
- Number of Sellers
Click to expand a full offers breakdown showing each seller's fulfillment type (AMZ / FBA / FBM) and price.
- Category
Top-level Amazon category, resolved via the official SP-API categories endpoint — never a subcategory.
- Est. Monthly Sales
Estimated monthly sales volume. (Feature in active development.)
