Secure OAuth Connection

Your marketplace accounts are connected securely via OAuth. We never see your passwords.

  • Industry-standard OAuth 2.0 authentication
  • Tokens stored securely and encrypted
  • Revoke access anytime from your marketplace account
  • We only request permissions needed for listing

eBay Business Policies

If you use eBay business policies, they'll be automatically available:

  • Payment policies

  • Shipping policies
  • Select from your existing policies
  • Set defaults for faster listing

Works for Any Platform

On desktop, Facebook Marketplace, Poshmark, Mercari, Depop, Vinted, Whatnot, OfferUp, Etsy, and more are one click: our free Chrome extension opens the marketplace's own create form and fills the title, price, description, and photos — you review and click Post.

Everywhere else (and on your phone), every item has a paste kit: tap-to-copy buttons for the title, price, condition, and description in the order the platform's form asks for them, plus one-tap photo sharing to your phone's share sheet (or a zip download on desktop). List on Depop, Craigslist, OfferUp, or anywhere else you sell.
