Airflow

Project Overview

Airflow is a receiver that casts iPad / Mac screens wirelessly onto Windows PCs with sharp, low-latency video, shipping as a single exe that runs without Python, compilation, or manual dependencies. First launch auto-installs Apple Bonjour, after which iPad / Mac users pick iPad-Screen in Screen Mirroring. It picks the display mode by device: iPads get fullscreen mirroring while Macs get a 1:1 unstretched extended display, switchable anytime with F2. The receiver engine is UxPlay (GPL-3.0), the UI is PyQt6, and this project's code is MIT.

Turn the Windows desktop into an AirPlay target, mirroring iPads and extending Macs alike.

Key Features

• Device-adaptive display: fullscreen mirroring for iPads, 1:1 extended display for Macs, F2 to switch
• Borderless fullscreen topmost: the picture fills the screen, idle mice hide, and sleep is blocked while casting
• Video parameters: size, quality, frame rate, audio toggle, flip and rotation, auto-restarting the service on change
• Multi-monitor and tray: display picking, window position memory, tray icon, and close-to-tray
• Status badge: device name, resolution, frame rate, and connection duration always visible
• KVM sharing: bundled Deskflow lets one keyboard and mouse control both PC and Mac over port 24800

4. Grant Deskflow Accessibility permission on first use, then pushing the mouse to the screen's right edge switches keyboards

Notes

• KVM boundary: AirPlay itself carries no keyboard or mouse, sharing runs over a separate Deskflow channel
• Aspect ratio: fix distorted pictures by toggling mirroring/extended mode, or set the Mac's extended display to 1080p
• Component licensing: the Windows prebuilt UxPlay comes from yztshh/Uxplay-airplay, both GPL-3.0
