Every app becomes its own floating 3D panel. Not a screen mirror — Ethereal captures each window individually and streams it to your Quest headset.
The Ethereal Host app on your PC or Mac captures each window independently using platform-native APIs. On Windows, it uses the native window capture API. On macOS, it leverages ScreenCaptureKit for efficient, low-overhead capture.
Each window is encoded separately using hardware-accelerated encoding and streamed directly to your Quest headset. This per-window architecture means every app gets its own video stream — so you can resize, reposition, and interact with each panel independently.
The result: under 20ms latency from your PC to your Quest. Your windows feel native, not remote. No virtual monitors, no screen mirroring — just your actual apps floating in space.
Place your browser above your IDE, pin Slack to the left, put Spotify behind you. Every window goes exactly where you want it in 3D space.
Make your code editor huge and your chat window small. Each panel resizes independently — no one-size-fits-all virtual monitor.
Individual panels look natural in passthrough mode. Your real desk, keyboard, and coffee plus floating apps — the best of both worlds.
Apps aren't trapped in virtual monitors. Every window floats freely in your space. No edges, no bezels, no limits.
Per-window streaming works on Windows and macOS, streaming to any supported Quest headset.
