Built For: Deal Hunters & Flippers

The Deal Finder That Scores Gold Listings Against Live Melt Value

Marketplace, Craigslist, eBay, Whatnot — open your saved searches in one tap, and the Chrome extension scores listings as you browse so you only chase the ones worth chasing.

Always free to use. Every new account unlocks all Pro features for 2 weeks — no credit card required.

Why It Works ↓

Quick answer: Nu Stack's Saved Searches open gold and silver searches on Facebook Marketplace, Craigslist, eBay, and Whatnot in one tap, and the Treasure Hunter Chrome extension (Pro) scores each listing you browse against live spot — so flippers spend time closing deals, not doing math.

Frequently Asked Questions

Does Nu Stack scrape Facebook Marketplace automatically?

No. Saved Searches open the marketplace's own search in your browser, and the Chrome extension scores the listings you're already looking at. Nu Stack doesn't run a background scanner and doesn't bypass any platform's terms of service.

Is the deal scanner included in the free tier?

Saved Searches links are free. The Chrome Extension that scores listings as you browse is part of the Pro plan ($9.99/mo) — included free for 14 days on every new account.

Can I track which platforms I make the most money on?

Yes. Performance Tracking breaks down realized profit by source, metal, and time period. Most flippers find one or two channels carry the bulk of their margin.
