Introduction
Low-latency desktop and game streaming from a Linux or Windows host to any of your devices.
punktfunk streams your desktop or games to your other devices — a laptop, a Mac, a tablet, a TV — at low latency and at each device's own resolution and refresh rate. Run the host on a Linux machine or a Windows PC, connect a client, and you're streaming.
It's built for the things that make streaming feel native:
- Your device's exact mode. The host spins up a virtual display sized to the client that's connecting — 1080p60 to your laptop, 1440p120 to your desktop, 4K to your TV — at the same time. No letterboxing, no scaling, no juggling your real monitors. On Windows that's punktfunk's own indirect display driver, frames pushed straight in — so there's no physical monitor or dummy HDMI plug to deal with, even on the secure desktop.
- Low latency, GPU end to end. Frames go straight from the compositor to the GPU encoder (NVENC) with zero CPU copies, and over a transport tuned for responsiveness rather than throughput.
- Works with the apps you already have. punktfunk also speaks the GameStream protocol, so with
--gamestreamany Moonlight client connects — alongside a faster native protocol with dedicated apps for macOS, iOS, tvOS, Linux, Windows, and Android. - Secure by default. Hosts require a one-time PIN pairing; after that, devices reconnect on a pinned identity. No accounts, no cloud.

How It Works
The ideas behind punktfunk in a few minutes — virtual displays, the two protocols, pairing.
Quick Start
From nothing to streaming: set up a host and connect your first client.
Host Setup
Install on Ubuntu, Fedora, Arch, Bazzite, SteamOS, or Windows.
Connect a Client
Stream with the native app for your device — macOS, Linux, Windows, Android — or any Moonlight client.

What you need
- A host with a supported GPU — either a Linux machine running one of the supported setups (Ubuntu, Fedora, Arch, or Bazzite), or a Windows PC.
- A client device to stream to — there are native apps for macOS, iOS/iPadOS, tvOS, Linux, Windows, and Android, plus any device that runs Moonlight.
- Both on the same network (LAN or VPN). punktfunk is designed for a trusted local network.
