Moonlight (formerly Limelight) is an open source implementation of NVIDIA's GameStream protocol. We implemented the protocol used by the NVIDIA Shield and wrote a set of 3rd party clients.

You can stream your collection of PC games from your GameStream-compatible PC to any supported device and play them remotely. Moonlight is perfect for gaming on the go without sacrificing the graphics and game selection available on PC.

Stream at up to 4K resolution

If you can see it on your PC, you can stream it using Moonlight, including your full Windows desktop at 4K 120 FPS with a capable client.

Support for 120 FPS streaming

Stream at up to 120 FPS using the new Moonlight PC client with the option to disable V-Sync for the lowest possible latency.

Run your own cloud gaming server

You can host your own gaming server on many residential ISPs by just installing the Moonlight Internet Hosting Tool on your gaming PC.

Multiple client platforms

If you have an Android device, iOS device, Apple TV, PC or Mac, Chromebook, PS Vita, or even a Raspberry Pi, you can use Moonlight to stream games to it.

Open source

The code for our Moonlight clients is hosted on GitHub under the GPLv3 license. We welcome contributions and would be happy to help with ports to new platforms.

Completely free

Moonlight is a project run by the community, not a company. We have no interest in pushing ads, bundled services, paid versions with extra features, or subscriptions.

What's New

New Features

  • Experimental YUV 4:4:4 support for improved text clarity during remote desktop usage
  • Host must be running latest Sunshine pre-release build or v0.24.0 (when released)
  • Sunshine only currently supports YUV 4:4:4 encoding on Windows hosts
  • HDR streaming is now supported with software decoding (requires GPU with Vulkan or Metal support)
  • Bitrate limit can now be increased to 500 Mbps
  • These bitrates are not officially supported but can improve image quality if client and host can handle it (Ethernet strongly recommended).
  • Audio decoding now uses 32-bit floating point format

Bugfixes

  • Fixed inability to connect to hosts on macOS Sequoia
  • Fixed incorrect color range when streaming with AV1 from a host with an AMD GPU
  • Fixed unexpected Left Control key input when pressing the AltGr key on Windows clients
  • Fixed unexpected tearing artifacts when streaming with Intel Ivy Bridge GPUs
  • Fixed Windows installer failures due to failed firewall exception registration
  • Fixed GUI breakage on Raspberry Pi OS Buster or Ubuntu Bionic
  • Fixed Vulkan video decoding crash with recent Nvidia drivers using the AppImage build
  • Silenced log message spam when streaming HDR using Vulkan Video decoding on Linux
  • Fixed inability to see video output on SpacemiT K1 due to incorrect overlay plane selection
  • Fixed suboptimal pixel format selection with non-hwaccel FFmpeg hardware decoders
  • Fixed incorrect hardware decoding warning on embedded systems that use custom OpenMAX hardware decoding patches
  • Fixed build failure of libplacebo renderer on 32-bit platforms
  • Updated community-contributed translations from Weblate

Dependency Updates:

  • Updated Qt in Windows and macOS builds to 6.7.2
  • Updated OpenSSL to 3.3.2
  • Updated libplacebo to 7.349.0
