Brook is a cross-platform programmable network tool written in Go that enables traffic routing, monitoring, and analysis across multiple operating systems and devices.
Brook addresses the need for flexible network traffic management by providing a programmable proxy and packet analysis system. It works by intercepting and routing network traffic through configurable protocols, allowing users to inspect, modify, and redirect connections. The tool supports multiple proxy modes and can operate at different network layers, making it suitable for both transparent traffic interception and explicit proxy scenarios.
Developers and network administrators should choose Brook if they need a unified tool that works consistently across iOS, Android, macOS, Windows, Linux, and OpenWrt devices. It suits projects requiring network monitoring, security testing, or custom traffic handling without platform-specific implementations. The tool's programmability through Brook Script allows users to define custom network behaviors beyond standard proxy functionality. Those working with embedded systems or routers will find the OpenWrt support particularly valuable, as it extends network tool capabilities to edge devices.
The project maintains active development with regular updates addressing cross-platform compatibility and feature expansion. The codebase shows ongoing refinement of client implementations across all supported platforms, indicating sustained effort to keep the tool functional on evolving operating systems. Documentation and examples are continuously maintained through the Brook Script Gallery, suggesting the maintainers actively support users in extending the tool's capabilities. The project demonstrates responsiveness to platform-specific requirements, as evidenced by dedicated articles and guides for macOS App Mode, Linux installation, and OpenWrt integration.
