Head to head
Judging Coursera on its own only gets you so far. Each page below puts it head to head with one other platform on cost, certificates, and how deep the free material goes, and every one of them ends in a pick rather than a shrug.
They run in order of how much subject matter the two platforms share, so the near-substitutes for Coursera come first and the ones that barely overlap sit at the end. Each card names what the other platform is best at, which is usually enough to tell whether the comparison is worth your time.
