Most Amazon seller software platforms are built around product research and launch. SentryKit is laser-focused on protecting products you already sell. We don’t try to be an all-in-one suite—we’re the best Amazon monitoring tool for sellers who need instant alerts, not bloated dashboards. Think of us as your 24/7 security guard, while tools like Helium10 are your market research department.
And the best part? You can track 1 ASIN for free, forever — no credit card, no commitments.
Even checking twice a day means 12+ hours of exposure if something goes wrong at night. Hijackers, ranking drops, and listing suppressions can cost you $500-$5,000 per day depending on your sales volume. SentryKit’s Amazon alerts cost less than one day of lost sales—and they work while you sleep.
25+ alert types including: hijackers on your Buy Box, ranking drops for unlimited keywords per ASIN, low inventory warnings, listing suppression/suspension, negative review bombs, main image changes, price changes, and more. Every Amazon FBA tool claims monitoring—we deliver alerts in under 30 minutes, not 8-hour batch updates.
Absolutely. Manage unlimited seller accounts and marketplaces (US, CA, UK, EU, etc.) from one dashboard. Perfect for agencies, brands with multiple storefronts, or sellers with separate business entities. Our Amazon seller management software is built to scale.
Average detection time is under 30 minutes. Most Amazon monitoring tools run checks every 4-8 hours. We run checks every 10-15 minutes on critical metrics. When a hijacker hits your listing at 2 AM, you’ll get an SMS by 2:20 AM—not 10 AM the next day.
