Nightjar streams games from your PC to Android phones, tablets and handhelds, Android TV and Fire TV, Windows and Linux. It speaks the Moonlight protocol, so it works with the host you already run, and it is built to make the stream feel local: hardware decoding tuned for each chip, frame pacing that follows your display, and recovery that keeps you in the game when the network hiccups.

A page for every game. Its store, the PC it runs on, whether it is running, and the exact settings the stream will use.	Every store in one place. Steam, Epic Games, GOG, EA app, Ubisoft Connect, Battle.net and Xbox, filtered with one press.
See every millisecond. The performance overlay shows the network and decoding, and the PC's CPU and GPU readings from a host that sends them.	Tune it while you play. With a Rubylight 3.0 PC, change the bitrate, frame rate and the PC's Radeon graphics settings without leaving the game.
A real PC keyboard. Esc, F1 to F12, arrows and sticky modifiers, by touch, controller or TV remote.	On the desktop too. The same engine and settings on Windows and Linux, with VRR and beam racing, and a row per store on Home.
Settings you can find. Sections on the left, a search that works with a controller, and every setting in plain words with a Reset beside each change.	Help built in. F1 opens getting started, every keyboard shortcut, your controller's buttons and fixes for common problems.

_{Screenshots and the trailer use Nightjar's offline demo with a sample library and an original test animation; the performance numbers shown in them are illustrations. Measured results are below. Home, store shelves and game pages need a host with the native library API (Rubylight 3.0).}

• Picture. H.264, HEVC and AV1 on the hardware decoder, tuned for each decoder family. HDR10 with any HDR-capable host; HDR10+, HLG and Dolby Vision where the PC, decoder and display support them. 10-bit SDR, full-chroma 4:4:4, and the PyroWave codec decoded on the GPU. Upscaling with FSR 1, Snapdragon GSR or, on Windows, the graphics card's video upscaler.
• Timing. Follows the display's refresh rate, including Android's adaptive refresh and VRR on the desktop. Hosts that support it receive phase-lock reports, so frames arrive just before the display needs them. The desktop client can also beam race.
• Network. Device controls bitrate adapts to loss, round-trip variation and decode headroom. Bitrate and frame rate can change during a stream, and error correction can follow measured loss, with hosts that accept it. Recover interrupted streams, on by default, returns to the running game after a transient failure, and Ride out network drops holds a stream through up to 60 seconds of silence.
• Sound. Stereo, 5.1, 7.1 and 7.1.4. Passthrough of PCM, Dolby Digital or Dolby Digital Plus to a receiver, soundbar or TV. A microphone with echo cancellation on every platform, plus noise suppression, gain and one-tap mute on Android.
• Controls. Up to 16 controllers with mapping per model. Direct USB drivers for DualSense (adaptive triggers, lightbar and haptics), Xbox and Switch Pro controllers. Trackpad, direct, multi-touch and local-cursor touch modes, native pen input, on-screen controls on Android, and a soft keyboard that opens when a text field on the PC takes focus.
• Library. With a Rubylight 3.0 PC, Home merges every paired PC's games, with a shelf per store on a TV, a page per game and Wake-on-LAN. Games from any host launch from Android TV's home screen, Beacon, ES-DE, Daijisho, Pegasus and the desktop command line.
• Sharing. With a Rubylight 3.0 PC: clipboard sync in both directions, clipboard images, file transfer, the PC's shared folders, and USB devices forwarded to the PC.
• Co-op. Take a free player slot in a Rubylight 3.0 PC's split-screen co-op session, or go back to your own seat.
• Diagnostics. A performance overlay in three levels of detail, a stream health report that explains stutter, an input latency test, a decoder benchmark that runs without a PC, frame timings as CSV, a connection test and redacted problem reports.
• Comfort. Every screen works with a controller or a TV remote as well as touch, mouse and keyboard. Layered settings with search and presets, high contrast, reduced motion, screen reader support, and 15 languages on Android.

Our own measurements, against a Rubylight PC with a Radeon RX 7900 XT:

Decoder benchmark results for other devices are in device results; the built-in benchmark measures yours.

Download from the latest release. Every release publishes the SHA-256 of each file in SHA256SUMS-<version>.txt.

Release APKs are signed with the Nightjar release key (certificate SHA-256 312ed322c7c29d1aec4fae4a3979ebcb557af44d821d7f4746c0968548eb630b), so every later release installs over the previous one. Outside Google Play, the Android app checks GitHub for new releases and asks before installing one; the Windows app reports a new release once per launch. The desktop packages are not code-signed.

Nightjar has its own application ID and pairs separately, so it installs beside Moonlight and other clients without affecting them. Installing the desktop client covers removal and the location of settings.

1. Install a Moonlight-compatible host on the PC, such as Sunshine, Apollo, Vibepollo or Rubylight.
2. Open Nightjar on the same network. It lists the PCs it finds; otherwise choose Add PC and enter the PC's address.
3. Select the PC and enter the PIN that Nightjar shows in the host's web UI. With a Rubylight PC you can instead choose Scan QR code and scan the code on its Devices page.
4. If the host grants permissions per device, allow this device to list, view and launch apps, and the input types you use.
5. Pick a game and play.

The quick start and pairing guide cover each step, including one-time PINs and Wake-on-LAN. To play outside your home network, see Play away from home.

Discovery, PIN pairing, Wake-on-LAN, the app library, H.264, HEVC and AV1, HDR10, surround sound, all input types, stream recovery and diagnostics work with every Moonlight-compatible host. Further features depend on what the host reports:

The Error correction setting and host-side automatic bitrate also work with Sunshine-based PCs that support them, and PyroWave works with any host that offers it. When a PC's host lacks a feature, Nightjar hides it or names the host setting or permission it requires. Host feature support lists every capability and the hosts known to provide it.

The documentation index lists every page. The most used:

The Android app builds with Gradle and JDK 21; its native code needs the Android NDK and Rust. The streaming engine and the desktop client are a Cargo workspace under protocol/, shared by both apps.

• Building Nightjar: toolchains, tests, signing, the release workflow and the documentation checks.
• Building the desktop client: Windows and Linux builds and packaging.

Report bugs and request features in the issue tracker. Device results explains how to submit your device's benchmark, and translations explains how to correct or add a language. The Android app ships in 15 languages; the desktop app in English and German.

Video, audio, input, clipboard contents and files travel only between your device and your PC. Nightjar contacts GitHub to check for updates and Moonlight's STUN server (stun.moonlight-stream.org) to learn the network's public address, so it can tell whether the PC is reachable from outside. On Android it also uses Moonlight's connection-test server (android.conntest.moonlight-stream.org) to diagnose connection failures. Problem reports stay on the device until you share them. The privacy policy has the details.

• moonlight-noir by derflacco, for decoder low-latency settings
• Nonary's moonlight-qt fork, the reference for the desktop client's VRR pacing and D3D11VA rendering
• Nonary/moonlight-common-c, for the DualSense waveform protocol
