Karing is a multi-protocol proxy client and network traffic router designed to manage and direct internet traffic through various proxy protocols. It functions as a proxy subscription manager that imports and converts server lists from multiple external formats and providers into a unified configuration.
The project features a cross-device synchronization system that keeps network routing settings and server lists consistent across multiple devices via cloud or local sharing. It includes a latency-based server selector that measures real-time response times to automatically connect to the fastest available proxy node.
The tool provides capabilities for network traffic routing and proxy subscription management, allowing users to define custom routing rules and group servers from different providers.
