Ultra-fast Unix Socket → TCP Proxy written in Zig.

socketcp exposes Unix domain sockets (e.g. /var/run/docker.sock) to TCP ports using a zero-copy, multi-threaded proxy. Ideal for containers, tooling, debugging, or securely exposing local services.

---

✨ Features

• ⚡ Blazing fast – written in Zig, tiny & optimized (~50–100 KB binaries)
• 🔁 Bidirectional streaming (supports REST, WebSockets, SSE, gRPC-over-HTTP)
• 🧵 Fully multi-threaded – each connection is handled in its own worker thread
• 🧷 Multiple socket mappings using --map
• 🪶 Tiny memory and CPU footprint

---

🚀 Usage

Single socket mapping:

socketcp --map /var/run/docker.sock=0.0.0.0:8080

Multi socket mappings:

socketcp --map /var/run/docker.sock=0.0.0.0:8080 --map /var/run/redis.sock=0.0.0.0:6379
