List once. Sell everywhere.
Crosslisting means putting the same item for sale on several marketplaces at once — more eyeballs, faster sales. Zyppi is a crosslisting app that starts from a photo: the AI writes one listing and formats it for each marketplace's fields, so listing on three platforms takes the effort of listing on none.
Why crosslist at all?
Every marketplace has its own buyers. A vintage tee might sit for weeks on eBay and sell in a day on Depop; a handbag moves faster on Poshmark. Sellers who list across multiple platforms consistently report faster sell-through than staying on one — the only reason everyone doesn't do it is that re-typing the same listing five times is miserable.
That's the problem crosslisting apps solve, and where Zyppi goes a step further: instead of copying a listing you typed, it creates the listing from your photo, then adapts it to each platform.
How is Zyppi different from other crosslisting apps?
Most established tools (Vendoo, List Perfectly, Crosslist, Flyp) are form-first: you type the item details in (or import them from one marketplace) and the tool copies your typing to the others. That saves the re-entry — but the listing still starts with you doing the data entry.
Zyppi is mobile-first and AI-first: snap the item where you found it, review the AI draft, done. Each marketplace's quirks — category trees, required item specifics, description conventions — are handled per platform, not pasted one-size-fits-all.
Is crosslisting allowed by the marketplaces?
Yes — listing the same item on multiple marketplaces is allowed by eBay, Poshmark, Mercari, Depop and the other major platforms. What gets sellers into trouble is selling the item twice because it stayed live elsewhere after selling. That's why delisting sold items quickly matters, and why we're building auto-delist into Zyppi from day one rather than selling it back to you as a premium tier.
Zyppi is in open beta. Post listings directly to eBay and Facebook Marketplace — live today — with Poshmark and Mercari and more launching in beta. Anything marked "roadmap" is in active development — join the beta and you'll get it the moment it ships.
Frequently asked questions
Can I publish directly to marketplaces from Zyppi today?
Yes — beta users post listings directly to eBay and Facebook Marketplace today. Poshmark, Mercari and more are launching in beta, and the AI already writes optimized listings for every marketplace while each integration lands.
Is crosslisting against marketplace rules?
No. eBay, Poshmark, Mercari, Depop and other major marketplaces allow the same item to be listed in multiple places. The rule of thumb: when it sells on one platform, take it down everywhere else promptly so you never sell one item twice.
