V2RayX is a macOS network proxy manager and graphical user interface designed to control V2Ray core configurations and manage network traffic routing. It functions as a configuration tool that translates visual user inputs into the required JSON files for the underlying proxy core.
The tool provides a menu-bar interface for modifying system-wide network settings and switching between proxy servers. It separates the graphical interface from the proxy network core to ensure that connectivity persists independently of the UI.
Traffic routing is handled through multiple modes, including global routing and the use of Proxy Auto-Config files to determine traffic direction. The application manages the proxy engine as a background system service to maintain reliability across user sessions.
