Why BrowserDisplay

Built for temporary side displays and clean demos

Browser first

No receiver app

A phone, tablet, or another computer can receive the stream as long as its browser supports WebRTC.

Clean workspace

Show only what matters

Virtual display mode isolates the demo surface while your main screen stays private.

One control surface

Sources, ports, QR code, viewer count, pairing code, and quality presets are managed in one place.

Architecture

A local display link

BrowserDisplay does not require a native receiver app. The Mac handles capture, encoding, and signaling; the browser receives and renders.

Capture

ScreenCaptureKit captures screens or windows; BetterDisplay provides the optional virtual display.

Signal

WebViewer opens from a local HTTP page and uses a pairing code to establish the session.

Stream

Video streams to the browser over WebRTC, with quality controlled by presets.
