Pawtograder
What it is
Pawtograder combines autograding, manual grading, office hours, discussion, a gradebook and analytics for computer science courses. Each commit can trigger tests through GitHub Actions, with per-test results in the grading interface. Rubrics support additive, deductive and multi-level criteria, line-level annotations and separate scoring for group members. The gradebook includes MathJS expression columns, drop-lowest calculations, CSV import and a student what-if mode. Office hours queues support text, video and screen sharing and can show a student's linked submission and failing test. Discussions can surface relevant threads for known errors and allow public or staff-only posts. Calendar feeds and Discord channel mirroring support course events; LTI 1.3 integrations with Canvas, Blackboard, Brightspace and Moodle are roadmap items. Optional AI-generated test hints and an MCP server for compatible AI clients are also listed. Instructors can use the community instance for evaluation or self-host on Kubernetes with Helm charts. The platform is GPLv3 open source; institutions self-hosting keep data on their infrastructure. Institutions must provide GitHub Actions runners.
