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).

| Clients | 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 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
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 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 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.
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:
- Any Flatpak distro (recommended) —
flatpak install https://flatpak.unom.io/io.unom.Punktfunk.flatpakreffrom the hostedflatpak.unom.iorepo, thenflatpak update; this is also what the Decky plugin launches. - Ubuntu / Debian —
apt install punktfunk-clientfrom the punktfunk apt registry. - Fedora / Bazzite —
rpm-ostree install punktfunk-clientfrom the Gitea RPM registry. - Arch —
sudo pacman -Sy punktfunk-clientfrom the signed binary repo (see Arch Linux).
Launch it, pick your host from the list, and stream. For scripting you can skip the host list and connect straight away:
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 and we'll add you (see Install a Client). Once added, open the app, pick your host, pair 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 is a proven alternative for Windows.
A headless CLI path exists for scripting/measurement:
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:
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 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.
