Clash Nyanpasu is a network proxy client and graphical user interface for managing Clash network cores. It functions as a proxy manager and traffic monitoring dashboard, allowing users to route system traffic and handle proxying through a visual interface.
The project distinguishes itself by providing a TUN mode proxy manager for controlling system-wide network tunneling. It features a core-agnostic API layer that standardizes communication between the interface and various interchangeable network core implementations.
The application covers proxy configuration management, including profile importing and automated synchronization of external provider lists. It provides tools for custom network routing, concurrent proxy latency testing, and real-time traffic monitoring of upload and download speeds. Additional capabilities include system log visualization, a built-in configuration editor, and the ability to manage network cores as background system services.
