ListFlow

Listflow is a lightweight, completely free browser extension built for e-commerce resellers, thrifters, and online boutique owners who want to scale their multichannel sales without high monthly software fees. It serves as a privacy-focused, client-side alternative to expensive cross-posting tools like Vendoo, List Perfectly, and Crosslist.com.

Instead of relying on restricted, cloud-based marketplace APIs that require storing sensitive passwords on external servers, Listflow operates entirely locally within your browser runtime environment. It analyzes the DOM layer of a source listing (such as an item on eBay) and instantly maps and auto-fills the product title, custom descriptions, condition notes, image arrays, and pricing structures directly into a target platform's web form (like Poshmark or Depop).

Key Features: • 1-Click Cross-Listing: Instantly duplicate and sync store inventory across major marketplaces in seconds. • 100% Data Privacy: Runs entirely client-side. Your marketplace credentials, account tokens, and store data never leave your device. • Automated Data Mapping: Eliminates tedious manual copy-pasting and human data-entry errors. • No Listing Restrictions: Enjoy unlimited cross-listing with zero artificial caps, no paywalls, and no monthly subscription fees.

Stop overpaying for bloated enterprise listing software. Streamline your reselling workflow, save hours of manual work, and retain 100% of your profit margins with Listflow.
