Hey Product Hunt! Travis here, founder of Grabbit.

Every time I wanted to buy something used, I ended up doing the same annoying workflow: search Facebook Marketplace, then Craigslist, then OfferUp, then Depop, then Mercari. Same hunt, over and over.

So I built Grabbit to bring secondhand search into one place. You can search across multiple marketplaces, browse unified results in one feed, and click through to the original listing when you’re ready to buy or message the seller.

But discovery is only half the problem.

The harder part is figuring out whether a listing is actually priced well — and staying on top of new listings before someone else grabs them.

That’s why Grabbit includes GrabScore to help you quickly see whether a listing looks great, good, fair, or overpriced, and saved search alerts so you can get notified when new matching products appear.

The goal is simple: less tab-hopping, less guesswork, and a faster way to find the right used item before it’s gone.

Grabbit is currently available for US searches. It’s free to use, and Product Hunt users can try Grabbit Plus free for 7 days.

If you try it, I’d especially love to know:

Did Grabbit make secondhand search feel meaningfully faster?
Did GrabScore help you judge listings more confidently?

Would love your honest feedback on what feels useful, confusing, or missing.
