Greenlight vs Moonlight Web

Greenlight is a free, open-source client for Xbox Cloud Gaming and streaming from Xbox One and Xbox Series consoles. It carries console video and audio, with gamepad and keyboard controls; rumble is supported on xCloud. An online friends list shows which friends are currently online. Greenlight is made with JavaScript and TypeScript, and runs on Linux, macOS, and Windows. Its WebUI can also make the client available over a network to devices using Chromium-based browsers. Downloads are offered as Flathub installations and precompiled release binaries. The V2 release is in maintenance mode: its developers plan critical bug fixes but no new features. Version 2.4.0 changed authentication from XAL to MSAL and added English, Russian, and Ukrainian localization; German was added in version 2.4.2. The application is reported to work on Steam Deck, with some small bugs and side effects. Greenlight says it is not affiliated with Microsoft, Xbox, or Moonlight.

Moonlight Web is a free, open-source self-hosted server that streams a gaming PC to devices with a modern browser. The server is installed only on the gaming PC; clients open a URL without installing an app or creating an account. The maker states support for streams up to 4K HDR at 240 fps and latency under 20 ms over Wi-Fi. Browser decoding uses WebCodecs for H.264, HEVC, and AV1, depending on available browser support. Supported controls include Xbox and PlayStation controllers with rumble, keyboard, pointer-lock mouse, touch trackpad, and virtual keyboard. The client can discover and pair with Sunshine, Wolf, and MultiSeat hosts. Remote sessions use direct peer-to-peer WebRTC, with an outgoing connection to an introduction server and no public web ports exposed. Sessions support up to four players, including the host. The gaming PC needs a hardware-encoding-capable GPU; Linux hosting also requires x64 and a sufficiently recent distribution. Linux-host HDR is not implemented.
