What Dodona is
Dodona is an online programming practice platform for students and instructors. It evaluates submitted code with automated checks for correctness, performance, and style.

Dodona supports more than 20 languages, including Python, JavaScript, HTML, and SQL. Teachers receive real-time individual and group learning analytics, can create exams and high-stakes tests, and can use plagiarism detection. Courses and exercises can be authored in external GitHub repositories and shared with colleagues. LTI connects institutional learning platforms, while sign-in options include Microsoft, Google Workspace, Smartschool, and SURFconext. Private projects, access controls, API tokens, GDPR compliance, and WCAG accessibility are listed. Data is hosted in the EEA on Microsoft Azure servers in Sweden Central. Dodona offers web, API, and extension access, with a free plan.
