OpenNOW is a native macOS cloud gaming client built with AppKit, Objective-C++, and WebRTC. It gives you a desktop-first way to sign in, browse games, and launch cloud streams.

• Native Mac interface with OAuth sign-in, persistent sessions, and account switching.
• Game catalog, library browsing, and a focused cloud-stream launch flow.
• Native WebRTC streaming with keyboard, mouse, gamepad, audio, microphone, and clipboard support.
• Stream tuning for resolution, FPS, codec, bitrate, region, HDR, and recovery behavior.
• Local upscaling, MP4 recording, stats HUD, Discord Rich Presence, and end-session diagnostics.

• macOS with AppKit/Cocoa support
• clang++ with C++20 and Objective-C ARC support
• Xcode 16 or newer
• WebRTC.framework or WebRTC.xcframework in third_party/webrtc-official

OpenNOW uses the Apple Sentry SDK through Swift Package Manager in OpenNOW.xcodeproj:

https://github.com/getsentry/sentry-cocoa.git

The project requires Sentry Cocoa 9.16.1 or newer and enables UI Profiling with trace lifecycle. To send the built-in verification event, run the app from Xcode with:

OPN_SENTRY_VERIFY=1

Set OPN_SENTRY_INFO_LOGS=1 to forward verbose info-level runtime logs to Sentry structured logs. Set OPN_SENTRY_TRACES_SAMPLE_RATE and OPN_SENTRY_PROFILE_SESSION_SAMPLE_RATE to tune trace and profile sampling.
