Artemis Qt vs Greenlight

Artemis Qt is a free client for streaming from NVIDIA GameStream, Apollo, and Sunshine servers on Windows, macOS, and Linux. It decodes video with hardware acceleration and supports H.264, HEVC, AV1, HDR streaming, 7.1 audio, multitouch, and gamepad play for up to 16 players, including local co-op. The client adds clipboard sync, custom server commands, one-time-password pairing, and UUID-based app launching, with a fallback to legacy app IDs when UUIDs are unavailable. Its in-stream menu includes fractional refresh-rate control, resolution scaling, and virtual display control. The project describes it as optimized for handhelds such as Steam Deck, with touch and gamepad navigation and power-efficient rendering. Downloads include Windows x64 and ARM64 builds, a universal macOS binary, and Linux x64 AppImage and Flatpak packages. AV1 requires Sunshine and a supported host GPU; YUV 4:4:4 is listed for Sunshine only. The project is licensed under GPL v3, and custom app ordering and input-only streaming are planned.

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.
