Action! vs Moonlight Game Streaming
Side-by-side comparison of features, pricing, ratings, and alternatives.
Action! by Mirillis is a Windows screen and gameplay recording tool built for capturing DirectX, OpenGL, and Vulkan games in high definition, alongside desktop activity, application windows, and web video. It supports live streaming directly to Twitch, YouTube, and Facebook, and can export finished recordings straight to YouTube or Facebook without a separate upload step. Recordings use hardware acceleration via NVIDIA NVENC, AMD APP, or Intel Quick Sync Video, along with Mirillis's own FICV codec, to keep capture performance smooth even during demanding gameplay. Additional features include a Greenscreen mode for removing webcam backgrounds, 120fps slow-motion capture, Time-Shift recording, and a companion Android remote-control app. It is sold as a single lifetime license rather than a subscription.
Moonlight is an open‑source client that lets you stream games from a Windows PC equipped with NVIDIA GameStream to virtually any device. It uses the same technology that powers NVIDIA Shield, delivering high‑quality video and responsive controls over a local network or the internet. The client runs on Windows, macOS, Linux, Android, and iOS, supporting Bluetooth and USB controllers, custom bitrate settings, and up to 4K/60 fps HDR streaming. Because it’s free and community‑maintained, Moonlight offers a cost‑effective alternative to commercial cloud‑gaming services.
