I first came across Flavio Copes a few years ago while searching for clear, practical guides on web development. He's a seasoned software engineer, author, and educator, well known for breaking down complex topics into approachable, easy-to-follow tutorials. One thing that really stood out to me early on was that Flavio makes many of his books available for free if you sign up for his newsletter.
What I didn't realize at the time, however, was that Flavio is also the creator of The Valley of Code - a comprehensive and completely free learning resource for programmers, with a strong focus on web development.
I recently rediscovered the site through one of his newsletters and noticed that it has been significantly updated. The Valley of Code is now modern, polished, and fully up to date, both in design and in content.
The site is organized into thirty sections, covering everything from fundamental concepts to more advanced topics such as networking and databases. These sections are clearly aimed at people entering the field, making them ideal as structured introductions for aspiring developers or anyone looking to strengthen their foundations.
If you’re learning web development or brushing up on the basics, The Valley of Code is worth a look. It's well-structured, easy to follow, and completely free - a high-quality resource that's great to see shared openly with the developer community.

Thanks for sharing! The Valley of Code is a awesome resource that I just discover. As you say: well-structured, easy to follow, and - last but not least - completely free.
You’re very welcome, Pascal! As I mentioned in my post, I actually stumbled upon it by accident myself - but I’m really glad I did. I’m happy to hear it will be useful to you!
This is a great shout — Flavio has a real talent for making fundamentals feel approachable without dumbing them down.
I’ve always appreciated how much emphasis he puts on foundations rather than chasing frameworks, and The Valley of Code reflects that really well. The fact that it’s structured, up to date, and fully free makes it especially valuable for people just starting out.
Resources like this age well because they focus on concepts that don’t change every six months.
Definitely a solid recommendation for anyone building their base 👍
Thanks, Dominik. I made the post hoping it would be useful to others on their webdev journey!
You definitely hit that goal — posts like this are especially valuable because they focus on foundations and mental models, not just tools or frameworks.
I’ve been thinking a lot about the same problem recently, which is why I put together a ChatGPT Tutorial for Beginners (2026 Edition) — less about prompts, more about how to reason, ask better questions, and avoid shallow learning when using AI.
Resources that help people build how to think rather than what to type tend to age the best. Thanks for sharing this one — it’s a great reference for anyone early in their journey 🚀
Cheers, Dominik. Always appreciate your feedback. Will have to check out your post too - sounds really rather interesting!
Cheers! I appreciate that — and no rush at all, it’s very much a “read when useful” kind of post 🙂
Either way, keep sharing resources like this. Thoughtful curation is just as valuable as writing tutorials, especially for people still building their footing in web dev.
Really nice find 👍
I’ve used Flavio’s resources before too, and his way of explaining things is very beginner-friendly without feeling “dumbed down.”
The Valley of Code is great because it feels like a structured path instead of random tutorials — especially helpful for people who get lost jumping between YouTube videos and blog posts.
Free, well-organized, and actually up to date is rare in dev learning sites.
Definitely a solid bookmark for anyone starting web dev or revising fundamentals.
I agree, Bhavin, it's rare to find such a resource online - especially one that is free!
This is a great resource! Glad you mentioned this since I am honing my skills in Full-Stack and I think "The Valley of Code" is a good resource for me. Gonna add this to my list in my Dev.to Profile if you do not mind!
Great find! :D
No problem, Francis. Glad that it helped!
The Valley of Code is a fantastic, free resource for aspiring developers—well-structured, up-to-date, and perfect for building a solid web development foundation!
