https://github.com/sean-der/stream-sniff is the code.

I wanted to help people debug/understand their live stream quality better. I would really appreciate people's feedback!

I see a constant stream of people saying 'my video is blurry' or 'why do I have so much latency' and I wanted to build something that helped people understand/diagnose. Also wanted to make something that runs in the browser so you can share/send a link to a friend (or on discord) to make debugging easier.

I am hoping to move it to https://github.com/glimesh org soon so it can sit next to broadcast-box.
