Programiz.com is one of the world's largest programming tutorials website in the world, homegrown in Nepal.
We are trying to build a critical feature for the website, an online compiler that can accept code through a web UI and display the result, similar to https://repl.it/languages/python3
We've tried to build it ourselves, but haven't gotten far. Our website receives more than 5 million sessions per month, so the system needs to be scalable, reliable and secure. That's why looking for some help from the community.
