## What it is
STUNTMAN is an open source STUN server and client implementation in C++, compliant with RFCs 5389, 5769, and 5780 with backwards compatibility for RFC 3489. It supports UDP and TCP over IPv4 and IPv6, runs in basic or full mode, and includes a client library for embedding STUN in applications.

## Use cases
- self-host a STUN server for WebRTC applications
- discover a client's public IP address and port behind NAT
- run NAT behavior and filtering detection tests
- test STUN clients against a local server
- embed STUN client functionality in a C++ application
- deploy a STUN service on Amazon EC2

## When to choose
- you need a self-hosted, RFC-compliant STUN server for WebRTC or VoIP
- you need both UDP and TCP support with IPv4 and IPv6
- you want a C++ STUN client library to embed in your own app
- you need NAT behavior detection in full mode with two IP interfaces

## When to avoid
- you need STUN over TLS, which is not implemented
- you need built-in authentication with user credential lookup out of the box
- you need a TURN relay server rather than just STUN
- you prefer a managed cloud STUN service instead of self-hosting
