How do online IDEs like Repl.it work?

I was curious about underlying technologies used in online IDEs. My random guess is they start a new docker container for each user session. Do you guys have any idea?

No need to guess. In most of these online IDEs you can probably explore and easily see for yourself. e.g. repl.it -> Emacs lisp -> M-x shell -> ps ax shows docker-init

Yeah just confirmed. Thanks.
