Partial A browser-based viewer is easy, but mirroring a Mac screen to another device with usable latency needs a native macOS capture component and low-latency video streaming, which vibe coding handles only partly.
What it would actually take: Build a macOS helper app using ScreenCaptureKit to capture displays, encode with VideoToolbox, and stream over WebRTC to a browser client served from a signaling server. Touch input relay and low-latency tuning across Wi-Fi need someone experienced in native macOS and real-time media.
