The Android app is in Google Play Internal Testing, so the public Play Store URL doesn't resolve for non-testers. Lead the Android install instructions with a "request a tester invite on Discord" CTA (the Play listing unlocks once a Google account is added to the test track), and surface the Discord + r/Punktfunk community links in the README, the docs intro, and the docs-site nav.

title: Introduction
|
|
description: 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 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 **host** with a supported GPU — either a **Linux** machine running one of the
|
|
[supported setups](/docs/requirements) (**Ubuntu** GNOME or KDE, **Fedora** KDE, or **Bazzite**), or
|
|
a **[Windows](/docs/windows-host) 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.
