kcp-go is a production-grade reliable UDP library for Go that provides ordered, error-checked stream delivery over UDP packets. It implements the KCP protocol and is built for applications that need lower latency than traditional TCP in challenging network environments. The library has been used in contexts such as online games, live broadcasting, file synchronization, and network acceleration. It exposes interfaces that are compatible with Go’s standard net.Conn style, making it easier for developers to integrate into existing networking code. kcp-go also includes advanced capabilities such as forward error correction, encryption support, packet-level tuning, and performance-oriented session management. It is intended for developers who need a fast, resilient transport layer and are comfortable tuning bandwidth, latency, and reliability tradeoffs.

Features

  • Reliable UDP transport
  • Forward error correction support
