I use the Syphon protocol for all of my work so I can share frames between my custom software and MadMapper to projection map my installations. I’ve always struggled to share work from a web browser in this fashion. There used to be a variety of wonderful tools that enabled this (Syphoner and ScreenCaptureSyphon), but Mac OS updates have made each tool increasingly unreliable and difficult to use. After much procrastination, I decided to write a native app to solve this problem for my own work.

 

Syphon Simple Browser is a native macOS web browser that shares its viewport in real-time (60fps) via the Syphon protocol for use in video mapping,  VJing, and live production software like MadMapper, VDMX, and Resolume.

• WKWebView/WebKit – Apple’s Safari-based web rendering engine
• Video Capture & Sharing:
• ScreenCaptureKit – GPU-accelerated window capture (macOS 12.3+) at 60 FPS
• Syphon Framework – Real-time video sharing between applications
• OpenGL – GPU texture handling for Syphon server

Performance:

• Hardware-accelerated rendering
• Configurable frame rates (15/30/60 FPS)
• Zero-copy GPU pipeline for minimal overhead

Notes:

• Save button (top right) saves the dimension of the browser for next launch
• Home button saves the current page as the homepage for next launch
• Added support for camera, mic, and web audio (without key/mouse event) in version 1.2
