They're serving up one big JS file: https://d250n10lsq5j8r.cloudfront.net/assets/application-aca...

control-f-ing for 'term' makes it look like it may even just be custom? https://github.com/search?q=var+AddTerminalShell&ref=reposea...

That's what I was thinking.. Found the JS file, Googled for AddTerminalShell to no avail. Didn't know if anyone else could recognize it or if it was custom.

Thanks for the help, though!

I also really love this terminal emulator and would like to use it myself. Any chance for you to release it?
