20 Best Computer Science MOOC / Non-credit Programs Online

We compared 20 Computer Science courses currently listed on Coursera, edX and Udemy, priced from $24.99 to $670.50. 18 of them teach the subject directly and 2 are built around a certification exam. 12 come from a named university or institution, including Princeton University, Goldsmiths, University of London & University of London and Institute of Science Tokyo. They are ordered by our CourseAsk score, which is built from how thoroughly each course describes what it teaches, whether it comes from a named institution, and how it compares on price — not from star ratings, which our course data does not include.

How these 20 courses were chosen

Every course below is a real, currently listed course from Coursera, edX, Udemy, matched to "Computer Science" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.

The grade on each entry scores how much the provider publishes about the course before you pay — the length and detail of the description, whether it lists learning outcomes and objectives — and whether a named university or institution stands behind it. A is fully documented and institution-backed; E is little more than a title and a price. Courses with almost nothing published are left ungraded rather than marked down, because an unknown course and a poor one are not the same thing.

There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $24.99 to $670.50, as listed by the provider when we last updated the page.

What the prices here tell you

The 19 priced courses on this page run from $24.99 to $670.50, with the middle of the range around $49.00 — a spread of $645.51. That is a wide gap for one subject. A higher price on this page usually reflects who is behind the course rather than how much material it contains, so it is worth opening two or three at different price points and comparing their syllabus before deciding.

Who is behind these courses

These courses come from Coursera, edX and Udemy. The platforms differ in how they sell: some charge once per course, others expect a subscription, and the listed price is not always what you pay at checkout after a promotion. 12 of these are produced by a named university or institution, including Princeton University, Goldsmiths, University of London & University of London and Institute of Science Tokyo — which usually means a fixed syllabus and a recognised certificate, rather than an individual instructor’s own course.

Courses versus exam preparation

2 of the entries here are built around a certification exam rather than teaching Computer Science from scratch. They are the right choice only if you already know the material and want to pass a specific exam; if you are starting out, pick one of the taught courses first and come back to exam preparation afterwards.

Before you enrol

Open the provider’s own page and check three things this comparison cannot tell you: when the course was last updated, what the syllabus actually covers in its later sections, and what recent learners say. Prices shown here are the provider’s listed price when we last rebuilt this page on 18 September 2026 — they change often, and a promotion can move them substantially. We earn a commission if you enrol through our links, which costs you nothing and never affects the order courses appear in.
