Hydro
Hydro is an online judge platform and competitive programming management system. It provides the infrastructure to host programming contests, manage a library of programming problems, and evaluate code submissions against predefined test cases and time limits.
The system utilizes a distributed code execution engine that scales judging tasks across multiple worker nodes to process high volumes of submissions. It is built as a modular judge framework, employing a plugin-based architecture that allows for the extension of system functionality without modifying the core source code.
The platform covers administrative capabilities including role-based access control with granular permissions and multi-tenant space isolation to segment users and data. It also includes tools for programming contest management with leaderboard control, problem set imports from external platforms, and configuration-driven language support to define compilation and execution logic.
Features
