Pre-call Testing and Diagnostics
Twilio provides the following tools for understanding clients' connections and diagnosing any potential problems before, during, or after a Video call.
Video Diagnostics Application
The Twilio Video Diagnostics Application is an open-source ReactJS application that tests participants’ device and software setup, connectivity with the Twilio Cloud, and network performance. It uses Twilio’s RTC Diagnostics SDK and Preflight API to provide end-users feedback about their network quality and device setup and also includes recommendations for improving their video call quality.
You can learn more about the Video Diagnostics App in the blog post or by visiting the README.
The RTC Diagnostics SDK and Preflight API can also be used independently in your application to test your participants’ device setup and network connectivity.
RTC Diagnostics SDK
This is a general WebRTC SDK and does not rely on Twilio infrastructure. You can incorporate it into your applications for pre-call testing or troubleshooting user issues during a call.
