Pion TURN is a Go toolkit for build TURN servers and clients. We wrote it to solve problems we had when building RTC projects.

• Deployable - Use modern tooling of the Go ecosystem. Stop generating config files.
• Embeddable - Include pion/turn in your existing applications. No need to manage another service.
• Extendable - TURN as an API so you can easily integrate with your existing monitoring and metrics.
• Maintainable - pion/turn is simple and well documented. Designed for learning and easy debugging.
• Portable - Quickly deploy to multiple architectures/platforms just by setting an environment variable.
• Safe - Stability and safety is important for network services. Go provides everything we need.
• Scalable - Create allocations and mutate state at runtime. Designed to make scaling easy.

We provide two simple client/server examples in examples. If more examples could be helpful please file an issue, we are always looking to expand and improve pion/turn to make it easier for developers.
