BreakCheck, right where you break.
The BreakCheck extension puts seller trust scores and certification status directly on Whatnot, eBay, TikTok Shop, and Fanatics Live — without leaving the platform. In development now.
Not available yet — but coming.
The extension is on our public roadmap. When it ships, it will surface BreakCheck data — seller ratings, certification status, revocation history — as an overlay on the live platforms you already use to buy breaks.
Want to be notified when it launches? Browse to a seller profile on BreakCheck and you can follow them — we'll notify you of status changes.
Seller overlay on Whatnot
See a seller's BreakCheck rating and Certified status directly on their Whatnot stream page — before you buy a spot.
eBay listing badges
BreakCheck data displayed alongside eBay break listings so you can evaluate a seller's cross-platform reputation without leaving the listing.
Certification quick-check
One-click verification of a seller's Certified status, issue date, and expiration — right from any supported platform.
Red-flag alerts
Get a visible alert if a seller has revoked certification, a pattern of unresolved disputes, or a recent platform switch.
TikTok Shop + Fanatics Live
Coverage planned for all four major break platforms at launch, with additional platforms added as the directory grows.
No tracking, no accounts
The extension reads BreakCheck's public data and displays it. It does not track your browsing or require an account to use.
In the meantime — verify any seller now.
BreakCheck's full database is available on the web today. Search a seller, read their review history, and check certification status before you drop money on a break.
