JellySell: The Fastest Way to Sell Online

Marketplace management for eBay, Etsy, Mercari, Depop, & Vinted

JellySell® is the FASTEST way to sell something online. Never log into a marketplace dashboard to manage your inventory again. 🚀 Crosslist in one click Post once and we'll mirror your listing to every connected marketplace automatically. Photos, descriptions, prices, sizes, and brands — all handled. When an item sells on one platform, it auto-delists or decrements stock on the others so you never double-sell.* 📦 Centralized orders Every sale across every marketplace lands in one orders page. Filter by status — To Ship, Pre-Transit, Shipped, Completed. Buyer addresses, item details, payouts, and tracking all visible at a glance. 🏷️ Built-in shipping Print and ship USPS, UPS, or FedEx labels directly from JellySell. Tracking auto-uploads to the marketplace the moment the label is generated. For platforms that supply their own prepaid labels, click Print Label and the label opens directly — no need to visit the marketplace's site. 💬 Unified messaging Reply to buyers across every connected marketplace from one inbox. Mark threads read, send messages, never miss a sale because you didn't open the right app. 📊 Real-time analytics Track views, sales, fees, and net earnings across all your sales channels. See what's selling, what's stale, and where your time is best spent. Crosslist for 100% free. No subscription, no per-listing fee. Certain optional features such as AI-powered listing creation and our centralized messaging inbox require a monthly maintenance fee. Supported marketplaces: eBay, Etsy, Depop, Mercari, Vinted, and more! JellySell® connects to eBay and Etsy via their official OAuth APIs server-side. The other supported marketplaces do not offer public seller APIs — JellySell® uses this Chrome extension to interact with them securely using your existing logged-in browser session. JellySell® never asks for your marketplace passwords. By using the JellySell® browser extension, you agree to JellySell's Terms of Service (https://www.jellysell.com/terms). *Auto-delisting and crosslisting for marketplaces without public APIs require Chrome to be open with this extension installed. eBay and Etsy work even when your browser is closed.
