Tor Explorer
by Luke Childs
Tor Explorer allows you to view information on the individual nodes that make up the Tor network. The initial download is around 7k and doesn't require JavaScript. It loads a few extra enhancements if your browser supports them. It's built as a progressive web app but also works well on older browsers too. More detailed information is in the GitHub repo readme.
