    The author covers Glitch and repl.it - so I suppose the definition of IDE is stretched enough for me to add two more candidates: Binder and Nextjournal. The notebook format is too often overlooked. And something like Nextjournal is pretty fast and flexible. These have many of the benefits of repl.it environments, but with a literate reading experience.
