Flexible and powerful for complex projects.


You need flexible grading logic: Complex projects require custom scripts and step-by-step test control.
Submissions vary wildly: Git repos, command-line files, nonstandard formats—your platform needs to keep up.
Students need more detailed feedback: Without the right interface, you’re stuck pasting comments across files.
Adapt grading to fit your course, no matter the language or complexity. Build tests that reflect your learning goals and give students feedback that’s accurate, meaningful, and aligned with how you teach.


Teach real-world Git skills without extra setup. Your students gain version control experience while you gain consistency.
Detailed feedback doesn’t have to slow you down. Deliver clear, contextual guidance at scale.
