Sing-box Universal Proxy Platform Primer: Lightweight Architecture, Config Syntax & Client Ecosystem

An exhaustive architectural exploration of Sing-box, the next-generation universal proxy platform. Covers Go-based high-concurrency network stack design, JSON configuration format, differences from Clash, and multi-platform client selection.

Key Takeaway (TL;DR): Sing-box is the most performant next-generation universal proxy core. Moving away from legacy YAML architectures, it features a native JSON schema and zero-copy routing pipeline with built-in VLESS Reality, TUIC v5, and Hysteria 2 support. It cuts memory usage to 35% of legacy Clash while improving single-thread network throughput by over 20%.

1. Architectural Highlights

  • Native modern protocol implementations without external binaries.
  • Binary rule-set compilation (.srs) for instant routing queries.
  • Clean JSON schema dividing inbounds, outbounds, DNS, and routing rules.
