About

We help sellers list at scale — without the busywork

MarketFlow is a Windows desktop app that automates Facebook Marketplace and Group posting for dealerships, agents, and high-volume resellers.

Posting inventory to Facebook Marketplace by hand is slow and repetitive — and it gets worse the more accounts and listings you manage. MarketFlow was built to take that work off your plate: import your inventory once, and let the app post it across every account, on a schedule, with human-like pacing.

We focus on three things that matter to high-volume sellers: Inventory (bring everything in from a CSV, cleanly), Auto Posting (turn ready listings into live posts automatically), and Groups (reach buyers browsing Facebook Groups, not just Marketplace search).

MarketFlow is local-first by design: your inventory and account credentials stay on your own machine. Every Facebook account runs in its own isolated browser profile with an optional dedicated proxy, so accounts never mix.

Multiple accounts, fully isolated

Every Facebook account runs in its own browser profile with separate storage and an optional dedicated proxy — accounts never mix.

Account health at a glance

Connected / login-required / needs-attention status for every profile.

Dashboard analytics

Posting health (posted / failed / remaining today), a 7-day activity chart, ready-inventory counts, and recent activity.

Local-first & private

Your inventory and credentials stay on your machine — nothing lives in someone else's cloud.
