Official image of Bitfocus Companion. Bitfocus Companion enables the reasonably priced Elgato Streamdeck to be a professional shotbox surface for an increasing amount of different presentation switchers, video playback software and broadcast equipment. You don't need an actual stream deck to use it. Companion both comes with a builtin stream deck emulator, a webpage for touch screens and the ability to trigger buttons via OSC, TCP, UDP, HTTP, WebSocket and ArtNet. It does the same job, just without the buttons.
