## What it is
CMS (Contest Management System) is a distributed, self-hosted platform for running and organizing programming contests, originally built for IOI 2012. It handles contest tasks, submissions, automated grading, scoring, and multiple contest formats.

## Use cases
- run a competitive programming contest
- host an online judge for programming competitions
- automatically grade contest submissions
- organize a school or olympiad informatics contest
- manage scoring and leaderboards for coding contests
- self-host a contest platform for training

## When to choose
- you need a battle-tested system for official programming contests like IOI-style olympiads
- you want distributed, self-hosted grading with support for many task and scoring types
- you need automated submission evaluation and ranking out of the box

## When to avoid
- you just need a simple code runner or single-user practice judge
- you want a lightweight hosted SaaS solution without self-hosting
- your contest is not programming-related

## Facets
- artifact type: application
- maturity: active
- function: web-framework, api-framework, testing, scheduling, self-hosted
- domain: education, developer-tools, web-development
- platform: python, self-hosted
- tags: competitive-programming, contest-management, online-judge, grading-system, ioi, automation, linux, web-server, docker
