A free open-source TURN and STUN server for NAT traversal in VoIP and WebRTC applications.
What is coturn?
Coturn is a free open-source TURN and STUN server that facilitates NAT traversal for VoIP and WebRTC applications. It solves the problem of establishing direct peer-to-peer connections between clients behind firewalls or NATs by relaying media traffic through a secure gateway. The server supports multiple transport protocols and authentication mechanisms to ensure reliable real-time communication.
Developers and system administrators building or deploying VoIP systems, WebRTC applications, or any real-time communication platform that requires reliable NAT traversal. It's particularly valuable for enterprises and services needing scalable, self-hosted TURN solutions.
Developers choose Coturn for its robust implementation of TURN/STUN standards, high performance under load, and flexibility in deployment and authentication. Its open-source nature, cross-platform support, and ability to integrate with various databases and monitoring tools make it a preferred alternative to proprietary TURN services.
