The Odin Project

Learning web programming online for free.
"What I wish I had when I was learning" and "Education should be free and accessible".

Not everyone has access to a computer science education or the funds to attend an intensive coding school and neither of those is right for everyone anyway.
This project is designed to fill in the gap for people who are trying to hack it on their own but still want a high quality education.

You learn best by actually building

The Odin Project curriculum is full of projects that will help you build a strong portfolio of work on Github to fill out your resume.

Motivation is fueled by working with others

The project is committed to connecting students together so they can stay motivated and learn faster.

Open source is best

Our curriculum and website are available on Github and we encourage students to actually contribute to the project itself!
