Test STUN servers for WebRTC connectivity

Go to https://tomchen.github.io/stun-server-test/

Enter STUN server URLs (one per line OR JavaScript/JSON array; with or without protocol 'stun:')

Example: stun.l.google.com:19302

My other WebRTC online tools:

• Symmetric NAT Test (GitHub repo)
• WebRTC P2P Chat Test (GitHub repo)
