Volcano Judge is an easy-to-use online judge and contest hosting system. You can see a live demo at https://volcanojudge.pythonanywhere.com.
Note that I built this judge as a learning project and it is not necessarily secure or efficient. However, it can be used by school clubs or small organizations looking for a simple solution to host fun programming competitions or events.
- Support for Python and C++:
- Python is sandboxed and available by default for all problems.
- C++ is not sandboxed/secure. It is available by default for contests and Volcano Judge can compile & run C++ programs, however, enabling C++ will make the system vulnerable to attacks (note that the C++ code will be isolated from the main directory when running, and safety measures have been enabled to reduce the risk of vulnerabilities).
- Authors can add custom time limits to all problems, and Volcano Judge will kill processes after the limit is exceeded.
- Easy-to-understand grading:
- Simple & instantaneous feedback when users submit their code.
- Enable custom checking & feedback on problems (e.g. a character limit on submissions for code golf style problems).

- Minimalistic Design:
- Volcano Judge features a simple Bootstrap-powered design.
- Email Verification:
- Built-in email verification for all users, via the admin's Gmail business account.
- Simple Comment System:
- Users can comment on all problem objects and can vote on comments authored by other users.
- Announcement/News System:
- Staff can publish important updates, such as contest announcements. These will be visible on the user dashboard.
- Support for HTML & Latex Problem Statements:
- When writing problem statements, approved authors may use HTML and Latex for math, tables, images, etc.
- Simple & Extensible Rating System:
- More details here: https://volcanojudge.pythonanywhere.com/about
- Syntax Highlighting & Autocompletion for Both Python & C++:
- Volcano Judge integrates the Ace Editor for syntax highlighting & autocompletion.
- The code editor serves as a working browser-based IDE, with the problem statement visible to the user as they write their code.
Volcano Judge features support for grading solutions in Python 3 and C++. These languages should be installed on the machine being used as the server and the grader will make use of version installed.
