13 sites where you can learn how to code online for free or close to it

Free to audit most courses, paid certificates and advanced degrees

Coursera has courses, MasterTracks, Specializations, professional certificates, and one guided project for coding offered from notable universities like Duke, Stanford, and Princeton, and companies like IBM and Google. There's something for both beginners and advanced learners, and while courses can typically be audited for free, certificates and graded work are usually behind a paywall. 

Specializations and professional certificates typically have a free 7-day trial and after that are billed monthly — so the faster you complete it, the cheaper it will be. They can take anywhere from a few months to more than a year to finish and start around $39/month. Its MasterTrack options tend to be more costly — as in a few thousand dollars. 

Coursera also has an annual $399 subscription, Coursera Plus, that includes access to 90% of the site and may end up being a cheaper option — just make sure your desired courses are included.
