Sunshine: A Complete Overview of the Open-Source Game Streaming Host, Sunshine vs Moonlight

Sunshine is a self-hosted game-streaming host designed to work with Moonlight, enabling users to stream their PC games to other devices with very low latency. It functions as a personal cloud-gaming server and supports a wide range of hardware, including AMD, Intel, and NVIDIA GPUs. Sunshine is open source, lightweight, and enables high-performance game streaming over local networks or the internet.

Sunshine

Sunshine is an advanced open-source, self-hosted game streaming platform designed to deliver high-performance, low-latency streaming to almost any device. Built as a modern, community-driven alternative to NVIDIA’s discontinued GameStream, Sunshine lets users turn their own gaming PC into a powerful cloud gaming server that works seamlessly with the Moonlight client.

By combining Sunshine on the host PC with Moonlight on the client device, users can enjoy smooth, ultra-responsive remote gameplay across local networks—or even over the internet with proper configuration.

How Sunshine Works

Sunshine runs on your PC and uses hardware video encoding (NVENC, AMF, or Intel Quick Sync) to capture and stream your game in real time. The encoded stream is sent to a compatible client such as Moonlight, which displays the video and returns keyboard, mouse, and controller inputs. The system creates a gaming experience that feels almost like playing directly on the host machine, thanks to Sunshine’s emphasis on low latency and efficient encoding.

Sunshine vs. Moonlight

Although they are often mentioned together, Sunshine and Moonlight serve different roles in the game-streaming process:

Sunshine is the server/host that runs on the gaming PC. Moonlight is the client/receiver that runs on devices like phones, tablets, TVs, or laptops. They work together to provide one of the most stable and high-performance remote gaming setups available.

Sunshine works with all major GPUs (NVIDIA, AMD, Intel). Moonlight works on almost every platform (Android, iOS, Windows, macOS, Linux, ChromeOS, smart TVs).

Sunshine handles: encoding the video stream, launching games, managing inputs, hosting the session, and providing the server-side of cloud gaming

Moonlight handles: decoding the video stream, displaying it to the user, sending controller/keyboard input back to the host, and running the client-side of streaming.

Together, they offer a streamlined, customizable cloud gaming experience without subscription fees. Whether you’re streaming to your phone in another room or connecting remotely from across the world, Sunshine provides a reliable, fast, and fully customizable solution.

Sunshine is one of the most powerful tools available for gamers who want complete control over their game-streaming environment. Its open-source nature, support for all major GPU platforms, and compatibility with Moonlight make it a top choice for anyone looking to build a personal cloud-gaming server.

• Sunshine → The server/host you install on your PC to stream games.
• Moonlight → The client app is installed on your phone, TV, tablet, or another PC.
• Sunshine → Community-built open-source replacement for NVIDIA GameStream.
• Moonlight → Client built to connect to NVIDIA GameStream (and now Sunshine).

Which is better?

You need both together:

Sunshine to host the session. Moonlight to receive the session. Sunshine is flexible and supports all GPUs; Moonlight is extremely stable and optimized for clients.
