NekoBoxForAndroid is a network utility for Android that functions as a system-wide VPN tunneling client. It leverages the Sing-Box engine to capture and redirect device traffic through a virtual network interface, providing a centralized platform for managing proxy connections and network routing.
The application distinguishes itself through its advanced configuration management, allowing users to define granular traffic rules based on domains, IP addresses, or specific applications. It supports complex network requirements by enabling multi-hop proxy chaining, custom DNS resolution strategies, and the injection of JSON-based configuration files to modify protocol behavior. Users can automate the maintenance of their server inventory by importing and syncing remote proxy subscriptions.
Beyond core routing, the tool provides extensive observability features, including real-time monitoring of network traffic, bandwidth usage, and proxy status through an integrated dashboard. It also supports security-focused configurations such as TLS parameter tuning and the loading of custom root certificates to ensure compatibility with restricted network environments. The application is designed to be extensible, allowing for the integration of external binary modules to support specialized network protocols.
