I run a small auto dealership and I’m tired of manually posting each vehicle to Facebook Marketplace. I need a Python-based desktop application that runs on Windows 10/11 and automates the entire “create listing” flow for cars, using text and images only. Here’s what I picture: • Simple GUI: a form where I can drop in the vehicle’s details (title, price, mileage, description) and drag-and-drop up to 10 photos. • Facebook authentication handled once, then reused safely on future sessions. • One-click “Post” button that publishes the listing to my dealership’s Marketplace profile exactly as if I had done it by hand. • Error feedback: if Facebook changes a field name or rejects an image, I want a clear message so I can fix and repost. • Log file or console window so I can see what the app attempted each time. • The compiled .exe plus readable source code. Package it with PyInstaller or a similar tool so installation is zero-hassle on a standard Windows laptop. Tech is up to you—Selenium, Playwright, or any headless browser approach you’re comfortable with, as long as Facebook detects it as a normal user session and the solution stays within TOS. I’ll test with a dozen vehicles; if every listing appears in Marketplace with the correct photos and descriptions, the job is done. Send over an outline of how you’ll approach login persistence and photo uploads, a rough timeline, and any similar work you’ve completed. I’m ready to start right away.
