CodeFast vs. Codédex vs. JavaScript vs. Maven Comparison Chart

Codédex is an online, interactive coding-learning platform that uses a gamified, adventure-style format to teach real programming languages and skills. Learners travel through “fantasy lands” corresponding to languages such as Python, HTML/CSS, JavaScript, React, and command-line tools (Git, GitHub), proceeding at their own pace while earning experience points, badges, and unlocking new regions as they progress. It combines bite-sized interactive lessons, an in-browser code editor for instant practice, and project-based tutorials to give users hands-on experience rather than just theory. With more than 200 hours of content, Codédex supports beginners with no prior coding experience and gradually builds up to more advanced topics, reinforcing learning through code challenges, exercises, and real-world projects. It fosters a supportive community through forums and events like monthly challenges and hackathons, helping motivate learners and provide peer support.

Our first cohorts sold out within a few hours. Apply Now to join the waitlist and secure your spot in the next cohort. Do you have knowledge to share with the world but don’t know where to start? Many creators are overwhelmed by the number of variables, unknown unknowns, and sheer amount of work involved in creating a complex digital product like a cohort-based course. That’s why Maven is accepting applications to our new cohort-based course on How to Build a Cohort-Based Course (so meta). Our course will make it easy for anyone to join us without a course--and have a fully complete course you’re proud to launch by the end of six weeks. Our company is fully remote, and we're assembling a team of extraordinary talent to revolutionize education on the Internet. We're looking for our first engineers as we gear up to launch courses with an incredible set of early instructors. Check out our open positions.
