Companion
Companion transforms the budget-friendly Elgato Stream Deck and similar controllers into professional control surfaces for a huge range of gear and software. From presentation switchers and broadcast hardware to playback tools and home automation, it delivers studio-grade control and puts powerful workflows right under your fingertips.
You don't even need a physical Stream Deck. Companion ships with a built-in emulator, a touch-friendly web page, and the ability to fire buttons through OSC, TCP, UDP, HTTP, WebSocket and ArtNet — same job, no hardware required.
