Gavel
A web-based judging system for hackathons and project expos that uses pairwise comparisons to rank projects fairly.
What is Gavel?
Gavel is an open-source judging system built for hackathons, project expos, and competitions. It uses pairwise comparisons to rank projects fairly and efficiently, solving the problem of judging many projects with limited judge time. The system automates the entire judging workflow, from inviting judges to displaying real-time rankings.
Event organizers, hackathon coordinators, and competition managers who need a scalable and fair way to judge projects. It's especially useful for events with many projects where judges cannot evaluate every entry.
Developers choose Gavel because it replaces manual or spreadsheet-based judging with an automated, algorithm-driven system that ensures fair rankings. Its unique pairwise comparison method provides more accurate results than traditional scoring, and its self-hosted nature gives organizers full control over their data and workflow.
