Twilio Video provides a range of tools to support the development journey of building, launching, and scaling a video app. These include Room Monitor for real-time information and metrics about a Twilio Video Room, Video Diagnostics App & SDK for testing participants' device and software setup, connectivity with the Twilio cloud, and network performance, Preflight API for testing connectivity to the Twilio cloud, Network Quality API for monitoring participants' networks and providing quality metrics, and Video Insights for analytics and aggregations. The development journey can be broken down into three stages: Build, Iterate & Launch, and Scale, each with its own set of challenges that these tools can help address. By leveraging these tools, developers can optimize their video roadmap, improve video quality, monitor and troubleshoot issues, and scale their video solution to meet growing demands.
