An investigation by Class Central discovered 1150+ Coursera courses that are still completely free, without a certificate. Others have assessment items behind a paywall.
Many Coursera courses are available to audit for free, but certain features like graded assignments, certificates, and mentorship may be paid features. This means you can select Audit the course and access the video lectures, discussion forums, and course readings for free. Be aware that audit for free options can be somewhat hidden during the registration process.

Individual courses and Specializations cost varying amounts. The price will appear when you click on the blue Enroll button on the left of the Coursera course information page. You must be logged into Coursera to see the pricing information. Courses may be available either on a subscription basis or for individual purchase.
Many Specializations run on a subscription basis costing between US$39-79 per month. Most offer a 7-day free trial, after which you will be billed. If you cancel within the free trial time, you will not be billed.
Coursera Plus is a single payment that gives access to around 2000 courses and Specializations for 12 months.
A small number of courses are not free. These are indicated by a small green $ symbol.
Online degrees offered through Coursera generally cost less than other online and on-campus degrees.
