Quick answer: FeedbackWhiz is a broad review-plus-monitoring platform spanning Amazon and Walmart, with listing-change alerts and profit analytics. EcomSanity is a focused, Amazon-only operations console with compliant review automation built in, at $9.90/month and a 250-request free tier. Choose FeedbackWhiz for multi-marketplace monitoring breadth; choose EcomSanity for a lean Amazon operating view.
FeedbackWhiz and EcomSanity overlap on review automation and diverge almost everywhere else. The right pick depends on how wide you need the tool to be.
The shared core
Both send Amazon's official Request a Review for eligible orders, handle the timing window, and avoid duplicate sends. The compliant approach — official call, no custom pitch, no incentives — is the same for both, and is covered in review request automation: what's allowed. FeedbackWhiz additionally offers custom buyer-seller message building, which carries more policy risk and, per buyer-seller messaging vs Request a Review, isn't the safe path for solicitation.
Where FeedbackWhiz is broader
FeedbackWhiz reaches beyond Amazon reviews:
- Listing-change monitoring — alerts when a title, image, category, or Buy Box status changes on your ASINs, useful for catching hijacks or suppression.
- Product review alerts across the catalog with sentiment.
- Order and profit analytics, including COGS-based profit if you maintain cost data.
- Walmart support, for sellers running both marketplaces.
For a multi-marketplace seller who wants listing-hijack alerts and profit tracking in the same tool as review automation, that breadth has real value.
Where EcomSanity is more focused
EcomSanity doesn't try to be a profit ledger or a Walmart tool. It's an Amazon operating console:
- Sales velocity across rolling windows and days of stock net of inbound and reserved units.
- Session-weighted Buy Box percentage and conversion per ASIN — so a listing losing the box quietly shows up against the traffic it's costing.
- Return rates with reasons and dispositions; aged-inventory surcharge risk; category-level sales.
- Compliant review automation with visible per-order history.
The design bet is that a seller is better served by a small set of decision-ready signals than by a wide dashboard that needs configuring. For profit accounting specifically, EcomSanity points you to a dedicated tool rather than half-doing it — see best sellerboard alternatives.

Which to choose
Choose FeedbackWhiz if you sell on Walmart as well as Amazon, want listing-hijack monitoring, and want profit tracking in the same subscription — and you're willing to maintain the cost data and configuration that breadth requires.
Choose EcomSanity if you're Amazon-only and want a tight operating view — velocity, stock, Buy Box, returns — with compliant review requests included, at a lower price and with less setup. It won't monitor Walmart or build a P&L, and it's deliberate about that. See best Amazon review request software for the broader comparison set.
EcomSanity connects via official SP-API authorization, sends Amazon's Request a Review for every eligible order, and puts the result next to the inventory, Buy Box, and return signals that actually drive an Amazon business — for $9.90/month, or free up to 250 requests.
