freeCodeCamp vs The Odin Project: which free curriculum should you start?
Last published
Table of Contents
The Odin Project has two full-stack routes, JavaScript and Ruby on Rails, with local development setup built-in as part of the curriculum (thank goodness, that tripped me up back in the day). freeCodeCamp gives you more subject choices through its web, Python and database coursework. Both are free, so I'd choose one based on the projects and stack I wanted to learn... and which stack is actually in demand in my local area.
I'd happily recommend either of these curricula without the need to do a paid course alongside it.
That said, if you'd rather pay a bit for a more in-depth and curated learning experience Boot.dev is a fantastic third option. Its continued interactivity is paid after the demo chapters, so I'd try those before deciding whether the structure was worth a subscription. However, the Boot.dev team puts an incredible amount of time and resources into their courses, so if your time is limited and you're willing to pay a bit for a more premium experience, it's worth considering.
Two free curricula, different routes
| freeCodeCamp | The Odin Project | |
|---|---|---|
| Price | Free courses, projects and certifications | Free curriculum |
| Routes | Web, Python, databases and other certifications | Foundations, then JavaScript or Ruby on Rails |
| Projects | Included in the curriculum | Included throughout the paths |
| Environment | Browser, editor and other learning options | Local development setup is part of the work |
| Support | Community resources | Volunteer-supported Discord |
freeCodeCamp gives you more subject choices
freeCodeCamp's curriculum lists responsive web design, JavaScript, frontend libraries, Python, relational databases, backend and full-stack coursework. That'll give you some options beyond the two web paths TOP offers.
Its FAQ says the courses, projects and certifications are free. I'd choose it when a specific certification sequence matched the work I wanted to do.
The FAQ estimates about 300 hours per certification. That's the provider's estimate, so you still gotta allow for your own pace. I'd HIGHLY recommend sticking to one route before trying to complete several. That's one of the biggest mistakes beginners make: jumping around from language to language, framework to framework, and never actually finishing anything. Just get those fundamentals locked in and then move on to the next thing.
Aaron White's review describes using the HTML and CSS material as a starting point for personal projects:
I went from a complete beginner, as in not even understanding the difference between HTML and CSS, to doing my own projects, including a crawler, where I'm debugging myself because I actually understand the code.

White also recommends building outside the curriculum. Finishing an exercise and deciding how to build your own project are different kinds of practice.
Odin makes local setup part of learning
Odin's paths begin with Foundations, then split into full-stack JavaScript or Ruby on Rails. Its About page describes projects throughout the curriculum and volunteer community support.
Choose it if you want that stack and local setup as part of learning (which for me, was a godsend). Read the installation guide first. Native Windows isn't supported. Odin recommends a Linux virtual machine for beginners and marks WSL2 as advanced (which I actually disagree with, I think WSL is best for most learners on Windows).
If you're using a locked-down computer where you can't configure the tools, fix that before committing to the path. Odin's guide also explains that some early exercises use browser sandboxes before the local environment.
Odin's appeal is specifically web development. Dilpreet Singh put it this way in a 2024 review:
It is a free and open source project that has a lot of great resources for web development. It made actually made me learn web development.

Start with the project you want to finish
Compare the next project in each path and choose one to finish. If I were already making progress in one curriculum, I'd just stay with it unless the stack, development environment or sequence no longer fit what I wanted to learn.
For a Python/Go backend route, Boot.dev's backend curriculum is another option. It does charge for continued interactive work after demo chapters, with later lessons remaining readable for free. Its listed career paths don't include frontend development, so it isn't a direct substitute for Odin's full-stack routes, but is a fantastic option for backend, devops, or data analyst learning. Reviewer Leopoldo Guba chose it for its premium structure:
I like how the program is structured. I chose the Backend Developer path in Go. TypeScript is also an option.

Frequently Asked Questions
Are both curricula free?
Yes. freeCodeCamp says its courses, projects and certifications are free. The Odin Project describes its full curriculum as free and open source.
Does The Odin Project work on native Windows?
Its installation guide says native Windows isn't supported as a development environment. It recommends a Linux virtual machine for beginners and marks WSL2 as advanced. macOS and Ubuntu are also supported.
Which teaches backend development?
Both include it. Odin offers JavaScript/Node.js and Ruby on Rails full-stack paths. freeCodeCamp lists backend and full-stack coursework alongside its other certifications.
