This repository is a web-based management panel for sing-box proxy servers, providing a Gin-based web UI and REST API for configuring inbounds, outbounds, clients, subscriptions, and traffic statistics. It includes custom protocol implementations for many proxy protocols (VMess, VLESS, Trojan, Shadowsocks, Hysteria, TUIC, etc.), session tracking, and subscription generation in multiple formats (plain, JSON, Clash). The architecture is modular with core, service, API, and sub packages, using SQLite for persistence and a cron job system for stats collection and maintenance. The codebase demonstrates strong engineering practices with reusable components like a session registry, graceful QUIC shutdown wrapper, and security middleware. However, it is tightly coupled to sing-box internals, requiring custom manager copies to preserve hot add/remove functionality that upstream dropped, and it has a history of migration-heavy schema evolution. The project is actively maintained with frequent commits, comprehensive testing, and multi-platform deployment support (Linux, Windows, Docker).
