Secure OAuth Connection

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

  • 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

  • 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.

On your phone, tap "Copy it step by step" on an item: save the photos first (the share sheet, or a zip download), then copy each field in the order that marketplace's form asks for it, and paste and post it yourself in the marketplace's app. Every item also keeps tap-to-copy buttons and a zip of its photos for Craigslist or anywhere else you sell. We never post to these marketplaces for you.
