freeCodeCamp.org's open-source codebase and curriculum. Learn to code for free.
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 community has already helped more than 10,000 people get their first developer job.
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.
freeCodeCamp.org offers several free developer certifications. Each of these certifications involves building 5 required web app projects, along with hundreds of optional coding challenges to help you prepare for those projects. We estimate that each certification will take a beginner programmer around 300 hours to earn.
Each of these 50 projects in the freeCodeCamp.org curriculum has its own agile user stories and automated tests. These help you build up your project incrementally and ensure you've fulfilled all the user stories before you submit it.
You can pull in these test suites through freeCodeCamp's CDN. This means you can build these projects on websites like CodePen and Replit - or even on your local computer's development environment.
Once you've earned a certification, you will always have it. You will always be able to link to it from your LinkedIn or resume. And when your prospective employers or freelance clients click that link, they'll see a verified certification specific to you.
The one exception to this is if we discover violations of our Academic Honesty Policy. When we catch people unambiguously plagiarizing (submitting other people's code or projects as their own without citation), we do what all rigorous institutions of learning should do - we revoke their certifications and ban those people.
Here are our ten core certifications:
Once you have earned the Responsive Web Design, Algorithms and Data Structures, Front End Development Libraries, Data Visualization, Back End Development and APIs, and Legacy Information Security and Quality Assurance certifications, you'll be able to claim your freeCodeCamp.org Full Stack Development Certification. This distinction signifies that you've completed around 1,800 hours of coding with a wide range of web development tools.
We also have 4 legacy certifications dating back to our 2015 curriculum, which is still available. All of the required projects for these legacy certifications will remain available on freeCodeCamp.org.

If you think you have found a vulnerability, please report responsibly. Don't create GitHub issues for security issues. Instead, please send an email to
[email protected] and we'll look into it immediately.
We appreciate any responsible disclosure of vulnerabilities that might impact the integrity of our platforms and users. While we do not offer any bounties or swags at the moment, we'll be happy to list your name in our Hall of Fame for security researchers.
