检查浏览器 WebRTC、ICE candidates、STUN 与 TURN
检查浏览器 WebRTC、ICE candidates、STUN 与 TURN The interface is designed to keep the important input, options, and result close together so you can finish a small development task without leaving your browser.
如何使用这个开发者工具
- Open the tool and confirm that your browser exposes RTCPeerConnection and RTCDataChannel.
- Add one or more STUN or TURN servers. TURN checks require the username and credential supplied by that server.
- Run the STUN/TURN check to see whether each service returns the candidate type it is expected to provide.
- Run the candidates check to inspect host, server-reflexive, peer-reflexive, relay, and mDNS-hidden candidates from this browser.
隐私与数据处理
The checks run in your current browser. STUN and TURN addresses, credentials, and candidate traffic go directly to the servers you configure; this site does not receive or store them. The configuration is saved only in this browser so you can reuse it on the next visit.

常见问题
Does this tool require a second browser?
No. The diagnostic suite checks browser support, ICE candidate gathering, and individual STUN/TURN service responses without creating a peer-to-peer session with another device.
Why does a STUN check need a srflx candidate?
A server-reflexive candidate shows that the STUN service returned the public address mapping needed for NAT traversal. A local host candidate alone does not prove that STUN answered.
Why does TURN need credentials?
TURN relays normally require authentication. The checker treats a relay candidate as success only when the server returns one using the credentials you supplied.
