Not everyone interested in learning online takes distance learning courses with the ambition of earning a degree, or even a certificate/diploma. Some students appreciate learning for the sake of learning. In fact, during the pandemic, learning for learning’s sake exploded. This is thanks to millions of adults seeking intellectual stimulation while stuck at home. Much of this virus-induced studying took place via online platforms offering MOOCs—massive open online courses. In this article, we’ll investigate the top ten free (or almost free) online learning platforms. We’ll also identify the fifteen most popular free online courses. Consider this your beginner’s guide to online learning!
Top 10 Online Learning Platforms
Online learning platforms have unique features and offerings. This can make it difficult if not impossible to rank alongside one another. Regarding popularity, Coursera and edX are clearly leading the pack. When it comes to quality and affordability, though, the platforms are comparable. Choosing the best place to learn online is really an individual choice. You must closely examine your own preference and learning style. Thus, we’ve listed our picks for the top 10 no-fee online learning platforms in random order:
Coursera

Founded in 2012, Coursera is an online learning platform designed to expand access to education to people around the world. Today, the site offers hundreds of free online courses from more than 200 different accredited universities. This includes top colleges like Duke, Yale, University of Michigan, UC Boulder, Arizona State University, California Institute of the Arts, and many more. So many of these free online courses are available through Coursera that it’s even possible to earn an entire degree on the platform!
Coursera isn’t just large, though; it’s also extremely diverse. The platform features many learning pathways. Examples include online college courses for credit, free online courses for senior citizens, and free courses online with certificates.
edX

A massive open online course provider and learning platform like Coursera, edX was even founded in the same year (i.e., 2012). Beginning with a single course from MIT, the platform would eventually grow to encompass thousands of individual courses (including free online courses and archived courses) hosted by over 150 different member institutions. Standout providers include top schools like the University of California- Berkeley, Harvard, Boston University, and the University of Texas system. With edX, students can work towards a degree or take a course purely for personal development. Likewise, career-oriented learners can choose to take classes with certificates. These certificates are available for professional development and career advancement.
Khan Academy

Unlike Coursera or edX, Khan Academy is a free platform that caters to younger students. Aside from PreK-12 classes, the site also offers courses for high school students, including AP Biology, AP Calculus, AP US History, and more. Though academics are the focus, Khan also offers “life skills” courses. Examples include classes for careers, personal finance, public speaking, political philosophy, college admissions, and entrepreneurship.
MIT Open Courseware

This platform is best for those looking for college courses for adults without all the bells and whistles. MIT Open Courseware is a large repository of MIT’s archived courses, including course material that is free and accessible to learners around the world. There is no fee or registration required to use MIT Open Courseware. But there is also no learner support like the kind you will find with more structured online learning platforms for massive open online courses like Coursera or edX, for example. With these free online courses, learning is truly self-paced. Yet, all materials for a particular course may not be available, depending on the instructor’s discretion. Still, this is an incredible resource for individuals seeking truly free classes for purely intellectual purposes. No degrees or certificates are issued through MIT Open Courseware.
Open Learning Initiative (OLI)

Operated by Carnegie Mellon University, the Open Learning Initiative—or OLI—is a resource for the university’s students as well as independent learners. Like MIT Open Courseware, OLI offers bare-bones online courses. This means students will have access to archived courses and course materials from top schools, but there are no instructors or free resources/support. Free online courses span various disciplines. Examples include arts and humanities, world literature, public speaking, life sciences, computer science and programming, mathematics and logic, data science, public health, and more.
FutureLearn

FutureLearn was founded in 2013. Since then, the free platform has formed partnerships with leading colleges and universities across the globe. These partner schools include reputable U.S. institutions of higher learning such as the University of California-Irvine, University of Colorado, Johns Hopkins University, Penn State University, and the University of Michigan,. Like most other e-learning sites, FutureLearn offers both free online courses as well as premium options. Premium options include certificates and even degrees. Topics include global history, political philosophy, world literature, and sustainable development among many others. FutureLearn has been criticized for being a little behind the times in terms of its interface and lack of mobile features. But, if you’re willing to dig a little and learn on your PC versus your Smartphone, there are some good opportunities to be had here at no charge.
Stanford Online

The opportunity to study at one of the most prestigious universities in the world at absolutely no cost and without rigorous admissions requirements? Opportunities like that don’t usually come along every day. With Stanford Online, they do, though. There is a bit of a catch. The free classes available from this accredited university are not-for-credit classes. They can’t be transferred or count towards a degree program. Still, adults looking for professional or personal development alone will find some quality offerings here. Free online courses span subjects such as engineering, design thinking, education, health and medicine, climate change, and arts and humanities.
Harvard University Online

While it may seem too good to be true, it is actually possible to take free classes at your own pace from the distinguished Harvard University. In fact, there are currently over 100 free online courses available through the school’s online division. These span topics such as computer science, political philosophy, humanities, social sciences, business, and more. In addition to these free classes, the university also offers nearly twice as many paid courses, many of them extremely affordable. These paid classes are usually associated with some sort of credential such as a certificate of completion.
Udacity

While it doesn’t exactly offer free college classes, Udacity does extend free opportunities. These are mostly for individuals with career advancement aspirations, particularly in the field of technology. The platform’s scholarships enable some eligible students to study topics such as machine learning, design thinking, artificial intelligence, and cybersecurity at no cost. Still, it’s important to note that students who do not receive financial aid will be responsible for fees associated with Udacity’s course offerings. Keep in mind, though, that payment plans and discounts are available. Though not affiliated with any college or university, Udacity does offer its own signature credentials in the form of “nanodegrees.”
OpenLearn (The Open University)

OpenLearn is affiliated with The Open University, a UK school. This platform offers open access to its catalog of approximately one thousand online courses free of charge. These free online courses span difficulty levels from introductory to advanced. A variety of academic disciplines from The Open University are also represented. Examples include business, modern psychology, education, political economy, sustainable development, and technology. There are no formal credentials awarded from The Open University for these free opportunities. But certificates of participation along with digital badges are available.
