JDoodle vs MATLAB Grader

JDoodle is an online programming platform for learning, teaching and practicing code. Its browser IDE runs programs on JDoodle machines, so it requires no local IDE installation, and it supports 114 languages, frameworks and databases. The Compiler API provides REST for final results and WebSocket for streaming output and interactive programs; API and embedded submissions run with time and memory limits. Runnable IDEs can be embedded in websites, course materials and learning management systems using three lines of HTML. Education features include assignments, automated correction and grading, question types, roles and result disclosures. Mobile apps support writing and running code on iOS and Android phones and tablets. The free Chrome extension has no Firefox or Safari version. The Free platform plan does not expire and needs no credit card; it includes 1,000 executions per day and 100 saved projects. A separate API Free plan gives 20 credits per day and no internet access. Pro costs $15 a month, and Student costs $4 a month billed yearly (US$48 a year). Paid API tiers start at $10 a month.

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.
