Ask HN: Any SaaS that offers embeddable REPL for teaching code?

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 (https://github.com/datacamp/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?
