An online judge for programming contests.

Unmaintained. Please fork and maintain if you wish. Here are some notes for a future maintainer:

1. The backend is not built for large-scale submissions over the web (it works OK for a small contest). The key missing component is a job queue for submissions. If this is implemented, then the backend will be able to scale.

Features

  • Supports C C++ Java Python PHP Ruby submissions
  • Integrated chat
  • Admin Control Panel
