Twitch Inspector

 Twitch Inspector is a free diagnostic tool offered by     Twitch     to help broadcasters evaluate and improve the quality of their streams. Its general capabilities include stream testing, troubleshooting, and analyzing video broadcasting quality. It works by providing users with real-time feedback on the stability and health of their stream, offering data such as bitrate stability, frame drops, and overall stream resolution. It features a straightforward user interface and gives comprehensive insights through its Stream Summary, a detailed report on each streaming session's performance. 

 One of the cool things you can do with Twitch Inspector is conduct test streams without going live, allowing you to fine-tune your settings and hardware setup for optimal performance. This is particularly useful when you're trying out new equipment or want to adjust your encoding settings. With Twitch Inspector, you can get results such as improved stream quality, reduced buffering, and a better overall viewer experience.
