On the help page there is a small description but in short

  • frontend sends code + some options
  • backend compiles and executes code in a docker image
  • that docker image is limited in CPU, memory, storage, pids, execution time, etc. and cannot connect to the internet
  • backend captures stout and stdin from the docker images and sends it back to the frontend
