Free forever for shoppers · No account needed to compare
FairSift checked eBay for you
Three steps between you and the better price.
Add FairSift to Chrome. It activates automatically on Amazon and eBay product pages — nothing to configure.
Browse products as you always do. FairSift reads the title and price from the page you're already viewing.
FairSift checks the other marketplace in real time and shows you which side is cheaper — instantly, on the page.
Every comparison on FairSift feeds anonymized market intelligence: what shoppers are actually looking at, where prices are moving, and where the cross-marketplace gaps are. Price with confidence instead of guessing.
See which products shoppers are comparing right now — demand signals before they show up in sales rank.
Track how prices move over time per product, so you know when to hold, discount, or restock.
Spot pricing gaps between marketplaces for repricing opportunities and arbitrage plays.
Search the full catalog of tracked products and drill into any item's demand and pricing detail.
Comparisons are free forever. Pay only if you want the market data behind them.
Everything else you're wondering.
Yes. Price comparisons for shoppers are free and unlimited, no account needed. You also get 5 free price-drop alerts — just create a free account so we know where to email you. The only paid product is FairSift Data ($9.95/month), the seller dashboard with demand signals and price trends.
The Chrome extension works on Amazon and eBay product pages, comparing prices across the two marketplaces in real time.
When you compare, we record the product title and observed prices to build market aggregates. Observations are stored with no user identifiers — no accounts, no IPs, no device IDs are ever attached to market data.
If you set a price-drop alert, we store your watched product, target price, and email address so we can notify you — that's the only time your account is linked to a product. Delete the watch anytime from the extension's Watch tab.
Yes. Manage or cancel your subscription anytime through the billing portal. You keep dashboard access until the end of your billing period.
Join the shoppers who never overpay — and the sellers who price with data.
