feat(decky): self-update without the store + Gaming-Mode launch polish, and ship the Steam Deck docs
Plugin self-update (no Decky store): CI publishes a per-channel manifest.json
({version, immutable per-version artifact, sha256}) beside the zip and bakes
update.json {channel, manifest} into the plugin. main.py `check_update` reads the
installed version from package.json (the value Decky reports — not plugin.json),
fetches the channel manifest, and the frontend shows an "Update to vX" button that
drives Decky Loader's own install RPC (root downloads + SHA-256-verifies + hot-reloads).
CI now stamps a plain-numeric semver (0.3.<run> canary / X.Y.Z stable) into
package.json — a -ciN suffix would mis-order under compare-versions.

Linux client: `--fullscreen` (plus SteamDeck/gamescope env fallback) enters GTK
fullscreen on stream start so Gaming-Mode chrome is hidden; native-mode resolution
falls back to the display's first monitor when the window isn't mapped yet (was
dropping to the 1080p floor — wrong on the Deck's 1280×800); add a confirmed
"Remove saved host" action (KnownHosts::remove_by_fp).

Docs: new docs/steam-deck.md (Decky install/pair/stream/self-update/troubleshooting),
wired into meta.json nav, and cross-linked from clients/install-client/channels. This
is the page docs.punktfunk.unom.io/docs/steam-deck — the website's download link
pointed at it before it existed; committing it makes that link resolve.

title: Install a Client
description: Install the punktfunk client for the device you're streaming to — Linux, Steam Deck, Windows, macOS, iOS, or Android.
---
This page is the **install path for each client device**. For what each client *is* and which to
pick, see [Clients](/docs/clients); to install the **host**, see [Install the Host](/docs/install).
Whichever client you install, the first connection needs a one-time [pairing](/docs/pairing).
> The links below are the **stable** channel (moves on `vX.Y.Z` releases). For the latest `main`
> build, use the **canary** channel — TestFlight / Play Internal, the `…Canary.flatpakref`, or the
> `canary/` download URLs. See [Release Channels](/docs/channels).
## Pick your device
| Device | Install |
|--------|---------|
| **Linux** desktop / laptop | [Flatpak](#linux-desktop-flatpak) (any distro) or native apt/rpm/Arch packages |
| **Steam Deck** | [Decky plugin](/docs/steam-deck) for Gaming Mode, or [Flatpak in Desktop Mode](#steam-deck) |
| **Windows** | [Signed MSIX](#windows) from the package registry |
| **macOS** | [Notarized `.dmg`](#macos) from the releases page |
| **iPhone / iPad / Apple TV** | [TestFlight beta](#ios-ipados-apple-tv) |
| **Android / Android TV** | [Beta — request access](#android) |
| Anything else (browser, old phone, TV) | [Moonlight](/docs/moonlight) |
## Linux desktop (Flatpak)
The **recommended** path on any Flatpak distro — install once, then `flatpak update` tracks new
builds. One command adds the signed `unom` remote, pulls the GNOME runtime from Flathub
automatically, and installs the client:
```sh
flatpak install --user https://flatpak.unom.io/io.unom.Punktfunk.flatpakref
flatpak run io.unom.Punktfunk
```
Updates, from then on:
```sh
flatpak update # or: flatpak update io.unom.Punktfunk
```
Prefer your native package manager? The client also ships as real packages (add the repo once —
see the linked guide — then it tracks updates with your normal `apt upgrade` / `rpm-ostree upgrade`):
| Distro | Install | Guide |
|--------|---------|-------|
| **Ubuntu / Debian** | `sudo apt install punktfunk-client` | [packaging/debian](https://git.unom.io/unom/punktfunk/src/branch/main/packaging/debian/README.md) |
| **Fedora / Bazzite** | `rpm-ostree install punktfunk-client` | [packaging/rpm](https://git.unom.io/unom/punktfunk/src/branch/main/packaging/rpm/README.md) |
| **Arch / SteamOS** | `punktfunk-client` from the `PKGBUILD` | [packaging/arch](https://git.unom.io/unom/punktfunk/src/branch/main/packaging/arch/README.md) |
Then launch it, pick your host from the list, and stream. For scripting, skip the picker:
```sh
punktfunk-client --connect <host>:9777
```
## Steam Deck
Most Deck users want **Gaming Mode**: install the **[Decky plugin](/docs/steam-deck)** and a
**punktfunk** panel lands in the Quick Access Menu, so you can discover hosts, pair with a PIN, and
stream **without dropping to the desktop**. Follow the **[Steam Deck (Decky) guide](/docs/steam-deck)**
— it walks through Decky Loader, the plugin, and the one-time client install.
> The plugin doesn't decode video itself — it launches the Flatpak client below. The Decky guide
> covers installing both, so start there: a Flatpak on its own won't add the Gaming Mode panel.
For **Desktop Mode** (or to add the client to Game Mode as a non-Steam app yourself), install the
Flatpak exactly as [above](#linux-desktop-flatpak) — it carries its own libadwaita + SDL3 and
survives SteamOS updates:
```sh
flatpak install --user https://flatpak.unom.io/io.unom.Punktfunk.flatpakref
```
See [packaging/flatpak](https://git.unom.io/unom/punktfunk/src/branch/main/packaging/flatpak/README.md).
## Windows
The Windows client ships as a **signed MSIX** in the package registry. Builds use a self-signed
certificate, so you import that certificate once before Windows will install the package.
1. Open the [packages page](https://git.unom.io/unom/-/packages) (generic group), find
**`punktfunk-client-windows`**, and download the newest **`.msix`** and its matching **`.cer`**.
2. **Trust the publisher certificate**, then install. The MSIX won't install until the certificate is
trusted — but it's the **same certificate for every release**, so this is genuinely one-time and
later updates need nothing. In an **admin** PowerShell:
```powershell
Import-Certificate -FilePath .\punktfunk-client-windows.cer `
-CertStoreLocation Cert:\LocalMachine\TrustedPeople
Add-AppxPackage .\punktfunk-client-windows.msix
```
If Windows reports a missing dependency, install the
[Windows App Runtime 2.x](https://learn.microsoft.com/windows/apps/windows-app-sdk/downloads)
(the MSIX depends on `Microsoft.WindowsAppRuntime.2`), then re-run `Add-AppxPackage`.
3. Launch **Punktfunk** from the Start menu and pick your host.
> The Windows client's hardware-decode (D3D11VA) and HDR paths are complete but still pending
> validation on real GPU hardware. If anything misbehaves, **[Moonlight](/docs/moonlight)** is a
> solid alternative for Windows.
## macOS
Download the notarized disk image from the [releases page](https://git.unom.io/unom/punktfunk/releases)
— `Punktfunk-<version>.dmg`. It's Developer-ID signed, notarized, and stapled, so Gatekeeper opens
it without warnings:
1. Open `Punktfunk-<version>.dmg` and drag **Punktfunk** to **Applications**.
2. Launch it, pick your host from *On this network*, and [pair](/docs/pairing).
The Mac app is also in the [TestFlight beta](https://testflight.apple.com/join/Qr7uSemk); the DMG
is the no-account path.
## iOS, iPadOS, Apple TV
The Apple app is in **TestFlight** beta — one universal build covers iPhone, iPad, Apple TV, and the
Mac. Install Apple's [TestFlight](https://apps.apple.com/app/testflight/id899247664) app, then join:
**[Join the punktfunk beta on TestFlight →](https://testflight.apple.com/join/Qr7uSemk)**
Open the app, and your hosts appear automatically under *On this network*.
## Android
The Android client (phone + Android TV) is in **Google Play Internal Testing**. To try it, request a
tester invite on our [**Discord**](https://discord.gg/kaPNvzMuGU) and we'll add your Google account to
the test track:
**[Request access on Discord →](https://discord.gg/kaPNvzMuGU)**
Once you're added, install it from Google Play, then open the app and pick your host:
**[Get punktfunk on Google Play →](https://play.google.com/store/apps/details?id=io.unom.punktfunk)**
_(only resolves once your account is on the tester list)_
## Anything else — Moonlight
Any device with a [Moonlight](https://moonlight-stream.org/) client (browser, old phone, smart TV)
connects over GameStream with no punktfunk-specific software. See
[Connect with Moonlight](/docs/moonlight).
