Master the Technology of Today, for Free
OpenCS is Aalto University's open online platform offering free computer science courses for anyone, anywhere. Whether you're starting your journey in tech or expanding your skills, you'll find high-quality, university-level learning at your fingertips.
Study at your own pace, mostly with no strict deadlines. For learners in Finland, official Aalto credits are available for some of the courses, while everyone worldwide gains valuable, practical knowledge in topics ranging from web development to modern programming languages.
From 1 Jan 2026, only adult learners and students whose home institution is a part of the FITech's new teaching cooperation agreement can receive ECTS credits from FITech courses; others may still take the courses but without credits. For details, see "Who can apply?."
