I'm CS faculty at a US university.  In the COVID era, I've committed to improving the students' online learning experience as much as I can using SaaS products that I can apply towards instruction.Right now, the coding in my assignments is in Jupyter notebooks and homework assignments.  I don't like it because there is a lot of time and friction (especially in setting up environments) between learning the content and practicing it.I like how code instruction sites like Datacamp and Plurasite have interactive coding environments in the browser that enable the student to practice a concept as soon as they learn it.  I'd love to pay a SaaS company to give me the ability to set up these sort of practice sections and embed them on lecture pages on my teaching platform.I want almost exactly the tool Datacamp released called Datacamp-Light (  But that doesn't look like an actual service and they don't support the packages/libraries I need.  Repl.it might be the answer, but does so much and I'm not sure it has my use case.  OReilly's Katacoda looks about right, but I think its meant to be enterprise software.Anybody have any advice?
