Chiaki-ng vs PS Remote Play

Chiaki-ng is a free, open-source client for PlayStation Remote Play and a next-generation continuation of Chiaki. It connects with PlayStation 4 and PlayStation 5 consoles. Installation guidance and packages cover Linux, Windows, and macOS, while the project also lists Android and other supported or potential platforms. Setup covers local console discovery and registration, plus remote play through PSN or a manual connection.

Streaming settings include video, stream, audio, and Wi-Fi options; the guide also describes PS5 HDR streaming with an H265 HDR codec option. Controller documentation covers mapping, gyro controls, haptics, adaptive triggers, DualSense and DualShock 4 use, and Steam Deck layouts. Scripts can wake a PlayStation and launch Chiaki using local or external addresses. The remote-connection guide says the PSN authentication token is stored locally. PSN remote connections support IPv4 only, and UDP hole punching may fail on some network types, requiring manual connection with port forwarding. PS4 remote play through PSN is limited to the account's main registered console. PS5 haptics and adaptive-trigger support are experimental and opt-in.
