Your games, one tap away
InPhase finds what you have installed across Steam, Epic, GOG, Xbox and more, with cover art. Pick a game and it launches on the PC as the stream starts.
Free and open source
Your gaming PC, on your other screen.
InPhase streams games and your whole Windows desktop to a browser on your phone, tablet or laptop. Nothing to install on the other device, no account, and nothing in the cloud between you and your PC.

Built for playing, not just watching
Hardware all the way
Your GPU encodes H.265 or H.264; your device decodes it in hardware. Frames go out over WebTransport and are repaired on the fly when Wi-Fi drops a few.
Keyboard, mouse, controller, touch
Full mouse capture and keyboard on a computer, a trackpad and keys on a phone. Plug a game controller into your phone or laptop and it works on the PC: setup installs the driver for you.
Private by design
Your PC serves its own secure page. Devices pair once with a PIN or QR code, remote access is off until you turn it on, and there is no InPhase server to trust.
Three steps
-
1
Install on your PC
Run InPhaseSetup.exe. InPhase sits in the system tray and shows a play address and a PIN.
-
2
Pair your device
Open the address in your phone's or laptop's browser and enter the PIN, or scan the QR code.

Play
Choose a game or the whole desktop. Settings for resolution, frame rate and quality are one tap away.
Needs Windows 10 (build 19041) or 11 with a hardware video encoder (NVIDIA, AMD or Intel) and the PC awake and signed in. Works best on the same home network; remote access over IPv6 or Tailscale is optional.
InPhase is made by one person
I'm Sam. I build InPhase in my spare time and give it away. If it saves you a subscription or lets you play from the couch, a coffee keeps the work going: more hardware to test on, faster fixes, and new features.
A coffee is a gift toward development; it doesn't buy support, features or a warranty.
