freeCodeCamp.org is a friendly community where you can learn to code for free. It is run by a donor-supported 501(c)(3) nonprofit to help millions of busy adults transition into tech.

Our full-stack web development and machine learning curriculum is completely free and self-paced. We have thousands of interactive coding challenges to help you expand your skills.

Become a Sponsor to freeCodeCamp

In 2014, a teacher started an open source community called freeCodeCamp.org. This community has grown to include millions of developers from around the world. Together, we have built:

💻 A free 3,000-hour programming curriculum.

🏛️ Forums and chat rooms where you can get coding help and feedback on your projects.

🧪 8,000+ coding tutorials.

🎒 1,000+ free YouTube courses on Computer Science, Data Science, and Machine Learning.

We are fully donor-supported. And we are extremely capital-efficient.

Last year our budget was only about $400,000. And yet we served more than 1 billion minutes of learning.

Each dollar you give to freeCodeCamp.org translates into 50 hours worth of learning for people around the world.

Sponsor us on GitHub or see other ways to donate.
