Sōzu is a lightweight, fast, always-up reverse proxy server.

Why use Sōzu?

  • Hot configurable: Sozu can receive configuration changes at runtime through secure unix sockets.
  • Upgrades without restarting: Sozu is always-up, meaning it upgrades itself while still processing requests.
  • Handles SSL: Sozu handles SSL, so your backend servers can focus on what they do best.
  • Protects your network: Sozu protect backends by shielding them behind the reverse proxy, limiting direct network access. Sozu uses Rust, a language primed for memory safety. And even if a worker is exploited, sozu workers are sandboxed.

To get started check out our documentation !

Exploring the source

  • lib/: the sozu-lib reverse proxy library contains the event loop management, the parsers and protocols
  • bin/: the sozu executable wraps the library in worker processes, and handle dynamic configuration
  • command: the sozu-command-lib contains all structures to interact with Sōzu
