CodeGrader in a Nutshell:

A plugin to ease the grading of student project submissions on the Marmoset Submit Server.


Your time is valuable to us. With automation, we save you the hassle of reading through code and let you make the important decisions.


With advanced code analysis, we aim to help you give high-quality detailed and constructive feedback to your students.


We believe grading should be as simple as it's always been. With one click, generate a grade and feedback report, and use it to auto-open, auto-fill, and auto-close forms in a separate grade server.


We're dedicated to continue improving the tool with your feedback. New features are always in development to make grading as easy as possible. Please submit bug reports and feature requests on GitHub.
