What Whatnot Spy does
Whatnot Spy is a free Chrome extension from Resellbot. Open any Whatnot livestream, your own or a competitor's, and it logs sales velocity and top buyers in real time, keeps the stream in your browser's local storage and exports a CSV. It also pulls follower lists from profiles.
It is a data capture tool, not an advisor: it shows you what sold but does not interpret it, compare it with other shows, or tell you what to do about it. It only works while the stream tab is open in your browser, so you cannot track more rooms than you have screens for.
What Ghost Agent does
Ghost Agent watches a live show as it happens, on your handle or a rival's, and reads chat velocity, room turnover, auction pacing and who just walked in. When momentum breaks it tells you what to do while the show is still savable. It alerts you when a known high spender enters your room, keeps a price book for your category built from what is actually clearing across the platform, and writes the post-show report with three concrete changes for next time.
It covers Whatnot, TikTok Live, eBay Live and Fanatics Live and tracks competitor shows across all of them. It is also the most expensive tool in this set, and it is wasted on a seller who goes live once a month.
When Whatnot Spy is the better pick
It is free, it takes thirty seconds to install, and for studying one rival's pricing before your own show the CSV is all you need.
When Ghost Agent is the better pick
You want more than one room tracked at a time, you do not want to keep a tab open all evening, you sell on TikTok Live, eBay Live or Fanatics Live as well, or you want the data interpreted and turned into a call during the show rather than exported afterwards.
