In their own words
DOMjudge
DOMjudge is a free system that automatically evaluates programming contest submissions and provides web interfaces for teams, juries, and the public. It is designed mainly for contests such as ICPC, where teams work on site against a fixed problem set and time frame. Judging can run across multiple judge hosts, and the system is designed to scale. Administrator tools support rejudging, clarifications, and detailed submission and judging information. A modular structure allows languages or compilers to be added, while a JSON REST API implements the ICPC Contest API with extensions, except for the optional team-members endpoint. DOMjudge imports Kattis Problem Tool packages, and Polygon2DOMjudge converts Codeforces Polygon exports. You can download and run it yourself; official Docker images are available for the domserver and judgehost. The listed latest stable release is version 9.0.1, dated 11 June 2026.
