Hi! I'm AutoJudge.

Send me your code and I'll grade it. I'll also run your contests and show who's ahead.

Demo: read a problem, write the solution, get AutoJudge's verdict, and climb the contest scoreboard

What can I do for you?

From your first exercise to the contest final, I'm the judge.

Your problems, your way

Write it, add test cases, share it. Whoever solves it gets my verdict.

Demo: writing a problem with hidden test cases, publishing it and adding it to a list

Your own programming contest

You pick the problems and the start time. I handle the grading, the scoreboard and the clock.

Demo: setting up a contest, adding problems, generating team cards and starting it

Compete as a team

Every solve earns a balloon. Watch the live scoreboard and see your team climb.

Demo: a team signs in with its card and follows its problems; after two attempts it solves problem B, with the penalty time added
