tsbridge is a production-grade reverse proxy that exposes multiple backend services on a Tailscale tailnet using isolated tsnet nodes per service. It supports static TOML configuration and dynamic Docker label discovery, with hot-reload, graceful shutdown, Prometheus metrics, and a composable middleware chain (access log, whois identity lookup, request ID, body size limits, header sanitization). The architecture is a single Go binary that manages per-service tsnet.Server instances, each with its own state directory and listener. External dependencies are Tailscale (tsnet), Docker (optional), and Prometheus. The codebase demonstrates strong engineering practices: interface-based abstractions (TSNetServer, config.Provider), typed error hierarchy, secret resolution with redaction, debounced event handling with exponential backoff, and comprehensive unit and integration tests. It is actively maintained with CI/CD, dependabot, and regular dependency updates.
