New-Seller-on-My-ASIN Instant Alert

Visit your ASIN's page and instantly see if any new seller appeared since your last check — catch hijacking early.

A new seller appearing on your ASIN — a hijacker, a diverter, an unauthorized reseller — can sit there for weeks before you notice. This extension checks the moment you visit the page and instantly flags anyone new since your last check, with a native notification and an alert inbox to review later. Features: Instant new-seller detection the moment you visit a product page Native Chrome notifications plus an on-page banner alert A running inbox of every alert, with unread tracking Free tier tracks up to 10 ASINs; Pro is unlimited Honest note: this checks for new sellers when you visit a page yourself — it does not run continuously in the background while you're not browsing. For genuinely 24/7 monitoring, that would require infrastructure beyond what a browser extension can honestly provide without a paid backend service.
