This looks very useful. I usually teach 20 to 30 students at a time and always struggle to provide like by line feedback. This should help.

For a slightly different use case, I wrote https://postcell.io/ for my classes. We use mostly Jupyter notebooks in my class and I mark certain cells with a special magic command. When students execute code in that cell, it is sent up to my server and I can see every student’s submission. I turn off student names and share the screen with the class. We then go through all the variations of answers and talk about the differences.

Although anyone can use it, the interface is probably a bit rough right now.
