MATLAB Grader vs Replit

MATLAB Grader lets instructors create interactive MATLAB coding assignments and automatically grade submissions for formative assessment, quizzes and exams. Its authoring environment runs in a browser and requires no installation or maintenance. Problem descriptions can include rich text, images, hyperlinks and LaTeX. Instructors can choose pass/fail or weighted grading, give contextual feedback, review attempt histories and examine analytics about concepts students find difficult. Learners can work in MATLAB Online, with submissions and results syncing back to MATLAB Grader without an extra login step. The service supports LMS platforms including Open edX, Blackboard Learn, D2L Brightspace, Canvas, Moodle and Sakai, plus other systems that support LTI Advantage. MathWorks states that it is certified for LTI 1.3 and related LTI Advantage services. The product is free with a MATLAB license that is current under maintenance. LMS integration requires a qualifying academic license, and participating learners must be enrolled students covered by it. It is available on Linux, macOS, Windows and the web.

Replit is a software creation platform where users can describe applications in natural language and refine them with an AI agent. The agent works through chat, tests and revises code, and can use a browser to produce reports and address issues. Its cloud development environment supports coding and collaboration in a browser, with automatic package installation and built-in authentication, database, hosting, and monitoring. Replit supports websites, mobile projects, designs, slides, animations, data visualizations, 3D, games, documents, and spreadsheets, with more than 100 integrations. The free Starter plan includes daily usage, but limits publishing to one live project and running one background task at a time. Replit Core costs $18 per month billed annually, and Pro costs $90 per month billed annually. Pro supports up to 15 collaborators and 50 viewers, and includes database rollback for up to 28 days. Replit is available on Android, iOS, Linux, macOS, Windows, and web. Its mobile apps support building, sharing, and publishing web apps; native iOS development uses the web version with Expo Go previews.
