Looking for a Comp Buddy alternative for Whatnot? Meet Ruby.
If you've been using — or shopping for — a Comp Buddy alternative, Ruby is a live Whatnot price checker built for buyers and flippers who don't want to overpay. Here's an honest look at how the main Whatnot pricing tools compare.

Why buyers pick Ruby
Ruby doesn't just show a price — it shows a Photo Match badge so you know the comp is the exact same item, prices every collectible category (not just cards), and offers a one-time lifetime option instead of a forever subscription. It runs on your own Mac and never uploads anything from your screen.
Switching is instant
Ruby installs in about two minutes: download after checkout, load the extension in Chrome, paste your key, and open a live Whatnot stream. That's it.
