codePost review
Free programming autograding with shared rubrics, annotations, and LMS integrations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
codePost is a web-based grading platform for computer science educators, including university instructors, teaching assistants, and teams running large programming courses. Its core workflow combines automated testing, code review, shared rubrics, grader management, and feedback. The platform also supports Jupyter Notebooks and PDFs, with anonymous grading and access through an SDK or REST API. It is available through web, API, and self-hosted platforms, and its pricing model is free.
Its standout capability is the combination of Docker-sandboxed autograding with collaborative feedback. Educators can use automated unit tests and custom test scripts, then add inline code annotations and comments or apply shared rubrics with point deductions. That gives teaching teams a way to pair repeatable programming checks with instructor-led review. Jupyter Notebook and PDF rendering broadens the workflow beyond standard source files, while LMS and educational-tool integrations connect codePost with Canvas, Blackboard, Brightspace, Pearson Revel, and other course systems. GitHub, CodePen, Code####, Replit, JSFiddle, and homegrown systems are also listed integrations.
The product's focus is both its clearest strength and its main boundary. It is well suited to programming assignments that need custom tests, code-specific comments, and coordinated grading across instructors or teaching assistants. Math autograding, written-work OCR, and question-bank support are not part of its stated category capabilities, so teams seeking a broader assessment platform should choose an alternative. The former codepost.io hosted service announced a permanent shutdown effective January 1, 2026, while codePost was donated to Rutgers; the Rutgers-hosted site remains live. Organizations evaluating adoption should therefore consider whether the current web, API, or self-hosted options fit their operating model.
