eturnal TURN Server

eturnal is a clean, scalable STUN and TURN server for Unix-like operating systems and Microsoft Windows. Clients can connect using UDP, TCP, or TLS over IPv4 or IPv6. For authentication, eturnal supports the mechanism described in the REST API for Access to TURN Services specification (in addition to static credentials). See the blog article on the initial release for a quick introduction.

eturnal is available as free and open source software and is straightforward to set up.
