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

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

**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 on NVIDIA, Vulkan Video or VAAPI on AMD and Intel on Linux, AMF or QSV on Windows — with no
  CPU copies on the paths where that's been validated (the
  [support matrix](/docs/support-matrix#zero-copy-capture-to-encode) says which), 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
  `--gamestream` any **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.

stream and links out to the detail as you need it. The rest of these are for when you want depth.

## What you need

- A **host** with an NVIDIA, AMD, or Intel GPU (there's a software encoder to fall back on without
  one) — either a **Linux** machine running one of the [supported setups](/docs/requirements)
  (**Ubuntu**, **Fedora**, **Arch**, **Bazzite**, or **SteamOS**), or a
  **[Windows](/docs/windows-host) PC**. What each combination can actually do — codecs, HDR, 4:4:4,
  cursor, input — is in the [Support matrix](/docs/support-matrix).
- 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.
