edX

edX is an online learning platform founded in 2012 by Harvard and MIT. Its focus is more academic than most of its competitors: the courses primarily come from renowned universities, supplemented by certificate programs, MicroMasters, and full online degree programs.

‍

A key feature of edX is the ability to audit courses for free and only pay if you want a certificate. For learners, this means you can dive into subjects like computer science or statistics from elite universities without spending a dime upfront. Teams can also be upskilled through edX for Business.

‍

Compared to Coursera, the offerings are more university-focused and less geared toward quick professional certifications. The practical downside: fewer courses from companies like Google, and there has been criticism regarding increased commercialization since the 2021 acquisition by the education company 2U.

‍

A great choice for anyone looking for academically rigorous content from top universities who likes the option to try things out for free first. If you're after practical, career-focused certifications, you might be better off looking at Coursera.
