Coursera's Top 100 Free Courses Draw Over 10
An analysis by Class Central identifies the 100 most popular free courses on Coursera, which have collectively garnered over 10.6 million enrollments.
Class Central has compiled a list of the 100 most popular free courses available on the Coursera platform. These courses have collectively attracted over 10.6 million enrollments.
Coursera, which went public in March 2021, is a major online course provider with a catalog exceeding 15,000 courses. According to Class Central's analysis of the company's IPO filing, Coursera generated $293.5 million in revenue in 2020 and $415.3 million in 2021. The platform experienced strong growth in 2023, adding 24 million new learners and increasing revenue by 21% to $636 million, though it faced challenges with revised projections and stock price drops in early 2024. In 2026, Coursera acquired competitor Udemy, though the two platforms reportedly remain separate.
Historically, Coursera offered completely free courses, but it later moved to monetize graded assignments and certificates. The platform transitioned to a 'free to audit' model and, in mid-2025, introduced a 'Preview Mode' that further reduced access to free content. Despite this, a Class Central investigation found over 470 courses remain completely free, excluding certificates.
