Is freeCodeCamp really free?
Yes. freeCodeCamp says every part of it is free, including the courses, projects and certifications. It is run by a donor-supported 501(c)(3) charity.
Is The Odin Project free?
Yes. The Odin Project says its full-stack curriculum is free and supported by an open-source community.
freeCodeCamp or The Odin Project: which should I start with?
Both are good. freeCodeCamp runs in the browser, so it is the easier first step. The Odin Project has you set up real tools on your own computer early, which is harder at first but closer to real work. Pick one and finish it rather than switching.
Can I get a job with only free courses?
People do. What employers check is what you can build and explain, not what the course cost. Finished projects online, on GitHub, and being able to talk through your code matter most.
Why pay for a mentor when the courses are free?
You are not paying for content. You are paying for direction, review of your own code and someone noticing when you stall. If you do not need those, stay free.
Can a ZAM mentor work with a free course I already started?
Yes. Your mentor starts from where you are. If a free curriculum is working for you, your roadmap can build on it.
