Re:Show HN: Collaborative text editing with unobtrusive mark... by c0da on Friday March 04, 2016 @09:57PM (#11228219)
It's almost pure front-end using Firebase + Firepad (https://firepad.io/). The editor uses CodeMirror (http://codemirror.net/) and custom highlighting rules. The backend (what little of it exists) is in Flask :)
