ResaleOS – Marketplace Connector

Connect the resale marketplaces you love to ResaleOS. No signing in again, no passwords shared.

Start selling across your favourite resale marketplaces from one place. ResaleOS is the operating system for resellers: list once and it goes everywhere, sell once and everywhere else updates. This extension is how you get started. Click Connect in ResaleOS and it links the marketplace accounts you're already using in this browser. No re-typing anything, no starting from scratch. The supported channels are shown in the listing screenshots and inside ResaleOS → Settings → Sales channels. GET SET UP IN UNDER A MINUTE 1. Add the extension. 2. Open ResaleOS — it recognises you automatically. 3. Settings → Sales channels → Connect. That's it, you're live. WHAT YOU GET • Crosslist to every connected marketplace in one go, from one form • Import the listings you already have, so you start with your whole inventory • Keep prices, photos and details in sync everywhere • Sold on one? It comes down on the others automatically • See sales, fees and profit across every channel in one dashboard BUILT FOR RESELLERS Whether you run a closet, a booth, a consignment shop or a full storefront, ResaleOS handles the busywork so you can get back to sourcing and selling. CHANNELS WITH AN OFFICIAL API Some marketplaces connect to ResaleOS directly through their own APIs — no extension needed. This one is for the channels that don't offer a public API. PRIVACY, PLAINLY The extension only ever connects the marketplaces you pick. It reads a marketplace session at the moment you click Connect and nothing else — it can't see your other tabs, your browsing history, or the contents of any page you visit, and it never touches your ResaleOS password.
