Problem

Instructors teaching CS practical tools (Git, shell, Docker) spend 10–15 minutes manually grading each student's lab assignment—5–7 hours per week for a 30-student course. Unlike programming assignments, there are virtually no auto-grading tools for shell scripts, Git commit histories, or Docker configurations, making instructor workload 2–3x higher than for standard programming courses.

Solution

Automatically executes student-submitted shell scripts, Git repositories, and Dockerfiles in isolated environments and grades them against expected outcomes. Instructors define grading rubrics in YAML, and the system auto-generates test cases, assigns partial credit, and provides automated feedback comments.

Target: CS practical tools course instructors (universities, bootcamps) managing courses of 20–100 students
Revenue Model: SaaS monthly: ~$59/month per course (500 gradings/month), additional gradings at ~$0.07 each, university site license ~$2,240/year
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
