GUI.for.SingBox is a desktop graphical interface client for managing the sing-box network proxy core. It functions as a network proxy manager and subscription manager, allowing users to configure routing rules, organize proxy profiles, and synchronize remote proxy server lists from external subscription providers.
The application distinguishes itself through an event-driven plugin architecture and a script-based configuration middleware, enabling users to extend core functionality and programmatically modify configuration values. It also features a system for cross-platform settings synchronization via WebDAV, Gists, or self-hosted services.
The platform covers a broad range of network capabilities, including the orchestration of virtual network interfaces for system-wide traffic routing, DNS resolution management, and the creation of custom routing rulesets. It provides observability tools through a traffic analysis dashboard that monitors data usage and performs IP geolocation lookups.
The tool includes administrative utilities for managing system proxy settings, handling UWP loopback exemptions on Windows, and configuring network adapters on macOS.
