This is an xterm.js-powered web app that runs a shell I wrote called devilish in a sandboxed environment. It’s purpose is to show off some of the features of devilish without requiring users to download, compile, and run it on their own machine. I originally wrote demo to do the same thing, but ran into difficulty with ASCII escape sequences and other terminal-specific features. xterm.js takes care of that, and allows anyone to explore in a safe, non-persistent sandbox. Networking is explicitly disabled, but Bash, tmux, and vim (among others) are installed and ready to use.
Give it a Spin!

python 3 :: for running the server.
npm :: for installing the dependencies.
firejail :: for running programs in a sandboxed chroot environment.
git :: for a quick git clone.
The above utilities should be installed (or readily available) if you are running a Unix derivative (such as Linux, macOS, or any of the BSD’s).
