Comprehensive WebRTC diagnostics similar to Twilio Network Test. Test peer connection establishment, ICE candidate gathering, STUN/TURN server connectivity, media device access, codec support, and connection quality metrics. Essential for real-time communication applications.
WebRTC enables peer-to-peer communication directly between browsers, reducing latency and server load. It uses ICE (Interactive Connectivity Establishment) to establish connections through firewalls and NATs, with STUN servers for discovery and TURN servers as fallback relays. This tester provides comprehensive WebRTC diagnostics to help you understand your connection capabilities.

Open the live webrtc test on this page and follow the prompts shown in the tester area. The tool runs directly in your browser, so you can check your device without installing additional desktop software or signing in.
Check browser permissions, confirm the device or browser feature is enabled, and reload the page if needed. Many browser-based testers depend on permission prompts, secure context support, or hardware access that must be approved before the test can run fully.
Video calling apps - verify WebRTC functionality. It can help you confirm whether the issue is caused by the hardware itself, a browser permission setting, or a system configuration problem before you spend more time debugging.
