Möbius Assessment vs PrairieLearn

Möbius Assessment provides online homework and assessment capabilities for mathematics and STEM courses. Its math engine supports complex STEM learning and math autograding, while the platform offers 15 question types, from multiple choice to open-ended responses. Assessments can use algorithmically generated and randomized questions for homework, placement, proctored, or adaptive tests. With Show your work, instructors can award partial credit when a final answer is wrong. Educators can configure more than 50 assignment properties, including scheduling, feedback, access conditions, and security. Assignments can guide students through different learning paths, reinforce content, or revisit earlier objectives; students receive immediate feedback and instructors get engagement and understanding data. Möbius integrates with Canvas, Moodle, Blackboard, and Brightspace, including single sign-on and grade syncing. It is certified for LTI 1.3 Core and supports LTI Advantage Deep Linking. DigitalEd describes the environment as mobile-ready and lists Android, iOS, Linux, macOS, web, and Windows. Pricing is available by request. DigitalEd says versions older than 12 months are unsupported.

PrairieLearn is an online assessment and learning system for instructors creating educational resources, assignments, practice, and tests. Instructors write questions as code; the system can generate and grade variants automatically and provide real-time feedback. Students can continue trying new variants until they achieve mastery. Supported response formats include numerical, multiple-choice, checkbox, dropdown, graphical, code, and ordered-block answers. The platform is described for in-class activities, homework, practice, proctored tests, and bring-your-own-device tests. It connects with learning management systems through LTI 1.3 for assignment linking and grade syncing, with integration primarily designed and documented for Canvas; its importer accepts QTI 1.2 content. PrairieLearn is open source and can be run or modified on institutional or individual infrastructure. The free plan covers instructors and courses with up to 20 students in each term. For larger courses, Basic costs $8, paid once per student and Premium costs $16, paid once per student. Local development is supported on macOS, Linux, or Windows inside WSL 2; Windows without WSL 2 is not supported for local installation.
