Six parallel audits swept the root docs, docs-site, every per-directory README, and the packaging docs; every claim below was verified against the source before editing. - README: Layout gains the six missing crates (pf-client-core, pf-presenter, pf-console-ui, pf-ffvk, pf-driver-proto, punktfunk-tray), clients/session, api/ and ci/; Linux/Windows client rows reflect the shell + Vulkan-session split and the Vulkan Video -> VAAPI/D3D11VA -> software decode chains; the "every client over a C ABI" claim is corrected (Rust clients link the core directly); tiered stats overlay + console shell noted; Apple row mentions AV1. - CONTRIBUTING: drop the dead CLAUDE.md link (deliberately untracked); point at the README's build/invariants sections. SECURITY: 0.9.0. - host-cli/pairing: --allow-pairing/--require-pairing are no-op legacy names — pairing is required by default, --allow-tofu is the real flag; document --data-port and --idle-timeout-ms. - configuration: document PUNKTFUNK_RECOVER_SESSION_CMD (session-crash recovery hook), PUNKTFUNK_MDNS, PUNKTFUNK_DATA_PORT. - virtual-displays/gnome: GNOME per-client scaling shipped (host- persisted) — flip the ❌ to ✅ and describe how it works. - stats: new "Detail levels" section (Off/Compact/Normal/Detailed + per-platform cycle gestures); retire the GTK hand-off note. - clients/install-client/status/roadmap: decode chains, Windows client validation narrowed to HDR-only pending, adaptive bitrate, console shell, Apple AV1, Windows host vendor list. - Sub-READMEs: clients/linux rewritten for the re-architecture; session Windows decode rung + d3d11va knob; Windows tiered overlay; Android minSdk 28; decky file table; host zerocopy/ path; scripts port 47992 and steamos-host.md; pf-dualsense source path. - packaging: canary version bases are tag-derived (<next-minor> via pf-version.sh/.ps1), codecs-extra not ffmpeg-full, document the pinned offline-Skia tarball + SKIA_BINARIES_URL and vulkan-headers. - Convert 15 dangling design/*.md links to the punktfunk-planning prose convention (those docs live in the private planning repo).

title: Clients
|
|
description: The ways to connect to a punktfunk host — the Apple app, Moonlight, or the Linux client.
|
|
---
|
|
|
|
A punktfunk host accepts clients over its own `punktfunk/1` protocol (the macOS, Linux, Windows, and
|
|
Android apps) and over GameStream (Moonlight). Pick whichever fits the device you're streaming *to*.
|
|
Ready to install?
|
|
**[Install a Client](/docs/install-client)** has the step-by-step for every device.
|
|
|
|
## Apple app (Mac, iPhone, iPad, Apple TV)
|
|
|
|
The native app for Apple devices speaks punktfunk's own [`punktfunk/1`](/docs/how-it-works#two-protocols)
|
|
protocol — the lowest-latency, most resilient path, with the full feature set:
|
|
|
|
- **Automatic host discovery** — hosts on your network appear under *On this network*; no IP typing.
|
|
- **PIN pairing** built in, and pinned reconnects after that.
|
|
- **Controllers**, including DualSense — rumble, adaptive triggers, lightbar, motion, and touchpad.
|
|
- A live **stats overlay** (resolution, fps, bitrate, latency) and a built-in **network speed test**
|
|
to pick a bitrate for your link.
|
|
|
|
Open the app, pick your host, [pair](/docs/pairing) once, and stream. It builds from the
|
|
`clients/apple` directory in the repo (Swift / VideoToolbox / Metal).
|
|
|
|
## Moonlight (anything else)
|
|
|
|
punktfunk also speaks the **GameStream** protocol, so any [Moonlight](https://moonlight-stream.org/)
|
|
client — a browser, a smart TV, an old phone, a games console — connects with no punktfunk-specific
|
|
software. (Most platforms also have a native punktfunk app below — Moonlight is the catch-all.) See
|
|
[Connect with Moonlight](/docs/moonlight).
|
|
|
|
This is the broadest-compatibility option and great for couch gaming. It doesn't use the native
|
|
protocol's FEC/encryption extensions, but for a healthy LAN that rarely matters.
|
|
|
|
## Linux desktop client (GTK4)
|
|
|
|
`punktfunk-client` is the native graphical Linux client — a GTK4 / libadwaita app that speaks
|
|
`punktfunk/1` directly, with hardware decode via Vulkan Video on every GPU vendor (including
|
|
NVIDIA), falling back to VAAPI dmabuf and then software, PipeWire audio, and SDL3 controllers
|
|
(rumble, lightbar, DualSense touchpad/motion). Like the Apple app it discovers hosts on your network
|
|
automatically, does PIN pairing, and pins reconnects.
|
|
|
|
It ships as a real package, not just a source build — full steps in
|
|
[Install a Client](/docs/install-client#linux-desktop-flatpak):
|
|
|
|
- **Any Flatpak distro (recommended)** — `flatpak install https://flatpak.unom.io/io.unom.Punktfunk.flatpakref`
|
|
from the hosted [`flatpak.unom.io`](/docs/install-client#linux-desktop-flatpak) repo, then
|
|
`flatpak update`; this is also what the [Decky plugin](/docs/steam-deck) launches.
|
|
- **Ubuntu / Debian** — `apt install punktfunk-client` from the punktfunk apt registry.
|
|
- **Fedora / Bazzite** — `rpm-ostree install punktfunk-client` from the Gitea RPM registry.
|
|
- **Arch** — `sudo pacman -Sy punktfunk-client` from the signed binary repo (see [Arch Linux](/docs/arch)).
|
|
|
|
Launch it, pick your host from the list, and stream. For scripting you can skip the host list and
|
|
connect straight away:
|
|
|
|
```sh
|
|
punktfunk-client --connect <host>:9777 # skip the picker, start a session immediately
|
|
```
|
|
|
|
## Android app (phone + Android TV)
|
|
|
|
The native Android app speaks `punktfunk/1` directly, on both phones and Android TV. It does hardware
|
|
HEVC decode (including HDR10), Opus audio with a mic uplink, game controllers with rumble and
|
|
DualSense feedback, automatic host discovery, PIN pairing with pinned reconnects, and a live stats
|
|
overlay — with D-pad and game-controller focus navigation for the couch. It builds from the
|
|
`clients/android` directory (Kotlin + a shared Rust core).
|
|
|
|
The app is in **Google Play Internal Testing** — request a tester invite on our
|
|
[**Discord**](https://discord.gg/kaPNvzMuGU) and we'll add you (see
|
|
[Install a Client](/docs/install-client#android)). Once added, open the app, pick your host,
|
|
[pair](/docs/pairing) once, and stream.
|
|
|
|
## Windows desktop client
|
|
|
|
`punktfunk-client` for Windows (`clients/windows`) is the native graphical client for Windows — pure
|
|
Rust, the same `punktfunk/1` core as the Apple, Linux, and Android apps, with a **WinUI 3** UI (host
|
|
list, settings, PIN pairing); the stream itself runs in punktfunk's Vulkan presenter. Its decoder
|
|
tries **Vulkan Video, then D3D11VA, then software**, with 10-bit/HDR present, WASAPI audio + mic,
|
|
SDL3 controllers (rumble, lightbar, DualSense), network discovery, and the full PIN-pairing trust
|
|
surface. It builds for both `x86_64` and `aarch64` and ships as a **signed MSIX**. Launch it and
|
|
pick a host from the list, just like the other native apps.
|
|
|
|
> Hardware decode is validated on NVIDIA and Intel GPUs; HDR10 is implemented with on-glass
|
|
> validation still pending. If anything misbehaves, **[Moonlight](/docs/moonlight)** is a proven
|
|
> alternative for Windows.
|
|
|
|
A headless CLI path exists for scripting/measurement:
|
|
|
|
```sh
|
|
punktfunk-client # open the WinUI 3 window (host list / settings)
|
|
punktfunk-client --discover # list hosts on the network
|
|
punktfunk-client --headless --connect <host>:9777 # no window: connect, count frames, print stats
|
|
```
|
|
|
|
Prefer the broadest compatibility, or no install? **Moonlight** also streams to Windows (see below).
|
|
|
|
## Linux reference client (headless)
|
|
|
|
`punktfunk-probe` (in the repo) is a command-line client for the native protocol, used for
|
|
testing, development, and latency measurement — not an everyday client. It connects, streams to a
|
|
file, runs the speed test, and can discover hosts:
|
|
|
|
```sh
|
|
punktfunk-probe --discover # list hosts on the network
|
|
punktfunk-probe --connect <host>:9777 --pin <fp> # connect to one
|
|
```
|
|
|
|
## Which should I use?
|
|
|
|
| You're streaming to… | Use |
|
|
|---|---|
|
|
| A Mac, iPhone, iPad, or Apple TV | The **Apple app** |
|
|
| A Linux desktop or laptop | **`punktfunk-client`** (GTK4) |
|
|
| A **Steam Deck** | The **[Decky plugin](/docs/steam-deck)** in Gaming Mode, or the GTK4 client in Desktop Mode |
|
|
| An Android phone or TV | The **Android app** |
|
|
| Windows | The native **`punktfunk-client`** (signed MSIX) or **Moonlight** |
|
|
| A browser, a smart TV, or any other device | **Moonlight** |
|
|
| Automated tests / latency measurement | **`punktfunk-probe`** (headless) |
|
|
|
|
Whichever you choose, the first connection needs a one-time [pairing](/docs/pairing).
