ComPAIR vs Eli Review

ComPAIR is a self-hosted web application for peer review in which students compare pairs of work and give feedback with both answers in view. Instructors can enable adaptive scores based on comparison outcomes and use them to assemble later pairs. The application has student, instructor, and system administrator roles with distinct permissions, plus rubric scoring and moderation tools. It supports LTI login, course membership, and grade updates; administrators configure LTI consumers with a key and secret. Documented authentication options also include username and password, CAS, and SAML 2.0. Learning analytics can be sent to a Learning Record Store through xAPI or Caliper, though both are disabled by default. The default attachment limit is 250 MB, with PDF, audio, video, and image extensions allowed. Administrators can manage whether instructors see student email addresses and CAS/SAML usernames; those fields are disabled by default. ComPAIR is open source under GPL-3.0 and freely available to download, install, and use. Its README documents deployment with Docker Compose, with access at localhost:8080. The tool is described as suitable for higher education and K-12 communities.

Eli Review is a web-based peer learning platform for courses that use peer review and related learning activities. Learners respond to criteria-based questions and prompts, and instructors can use helpfulness ratings to assess the usefulness of that feedback. Learners can make revision plans, submit revised drafts, and compare versions to see what changed. For course coordination, Eli can sync rosters from an LMS, automatically create review groups, send reminders, and schedule reusable assignment sequences. Its analytics track effort, participation, and reciprocity, while Data Stories highlight patterns in those areas and learner growth over time. Learners are also categorized as Strong, Steady, Emerging, or Stalled. Educators in higher education and K12 use Eli across disciplines. Instructor access is free for unlimited courses and all platform features. Student access costs 28.95 USD once for one term of four months, or $52.95 a year for 12 months. Institutional pricing varies by program size, expected use, and implementation goals.
