How It Works

Three steps.
One unfair edge.

01
Daily Scrape

Our crawler scans Facebook Marketplace every morning across your city, flagging vintage synthesizers and drum machines listed below their real market value. Roland, Moog, Korg, Sequential — nothing slips through.

02
Instant Alert

The moment a TR-808 hits at $400 or a Minimoog at $600, you get pinged. Not in a daily digest — instantly. First-mover advantage is the whole game in gear flipping, and Rarack gives you that edge.

03
Auto-List on eBay

Rarack generates your eBay listing automatically — pre-filled with optimal keywords, historical sold prices, and a competitive starting price. Buy it, click publish, and wait for the bids.
