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.
Möbius Assessment
Möbius Assessment provides online homework and assessment capabilities for mathematics and STEM courses. Its math engine supports complex STEM learning and math autograding, while the platform offers 15 question types, from multiple choice to open-ended responses. Assessments can use algorithmically generated and randomized questions for homework, placement, proctored, or adaptive tests. With Show your work, instructors can award partial credit when a final answer is wrong. Educators can configure more than 50 assignment properties, including scheduling, feedback, access conditions, and security. Assignments can guide students through different learning paths, reinforce content, or revisit earlier objectives; students receive immediate feedback and instructors get engagement and understanding data. Möbius integrates with Canvas, Moodle, Blackboard, and Brightspace, including single sign-on and grade syncing. It is certified for LTI 1.3 Core and supports LTI Advantage Deep Linking. DigitalEd describes the environment as mobile-ready and lists Android, iOS, Linux, macOS, web, and Windows. Pricing is available by request. DigitalEd says versions older than 12 months are unsupported.
