Sniff out what sells before everyone else.
SkuPup is a small, private tool a few friends built for our own reselling. It tracks everyday products on eBay (how many are listed, what they sell for, and how fast new sellers show up) and turns that into forecasts, profit math, and buy signals.
You'll be sent to discord.com to sign in. SkuPup never sees or asks for your password, and only invited members can get in.
Data in, decisions out.
Everything comes from eBay's official developer APIs. No scraping, no buying on anyone's behalf.
Track products
We add searches for everyday items we're considering, like phone mounts or kitchen gadgets.
Daily market scans
Each day SkuPup records prices, competing listings, and new-seller activity, and builds trends from them.
Forecasts & profit
It projects prices, estimates profit after eBay fees and our costs, and flags items worth a closer look.
Who runs SkuPup?
Is this a public service?
No. SkuPup isn't for sale and doesn't take sign-ups. It's used by a small group of friends who resell products, and access is by invitation only.
Why sign in with Discord?
Our group already talks on Discord, so it's the easiest way to know who's a member. Signing in uses Discord's official login on discord.com. SkuPup only receives your Discord username and avatar, never your password or email.
What data does SkuPup use?
Public, aggregate listing information from eBay's developer APIs (prices, listing counts, and seller activity), plus the products and costs our members enter. See the privacy policy.
How do I contact you?
Email support@skupup.com. Security reports are welcome too (see security.txt).
