Implementing a built in julia compiler inside my website

Hi, I am creating a platform for studying various topics. Among them I would like to have a running julia environment for students to run code on it and have tests done over their responses. Is there any resource I should be aware of, or where could I find more information about doing so. Thank you.

Just a fair warning: this is very hard. Beyond the technical challenges, anytime you expose arbitrary compute to the internet there are vast and endless social challenges. Compute is both expensive and valuable. Especially so, thanks to cryptocurrencies.
