title: Introduction
description: Low-latency desktop and game streaming from a Linux host to any of your devices.

import { Cards, Card } from 'fumadocs-ui/components/card'

**punktfunk** streams your Linux 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 with an NVIDIA GPU, 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.
- **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 speaks the GameStream protocol, so any
  **Moonlight** client connects out of the box — and 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.

## What you need

- A **Linux host** with an **NVIDIA GPU** (for the NVENC hardware encoder) running one of the
  [supported setups](/docs/requirements): **Ubuntu** (GNOME or KDE), **Fedora** (KDE), or **Bazzite**.
  A native [**Windows host**](/docs/windows-host) (NVIDIA-only) is also available.
- 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.
