In today's digital world, programming skills are becoming more and more valuable. Whether you want to change your career path, grow your own projects, or simply understand how new technologies work, there are many great resources online – for free.
Below, we share a list of 12 of the best free places and tools to help you enter the world of IT.
💡 Before you start learning – a quick note for business owners:
Are you looking for free courses because you want to build a website or an application for your company yourself to save money? Remember: learning to code from scratch to a level where you can create a secure, fast product requires at least 300-500 hours of hard work.
If you need a professional, ultra-fast website that starts selling from tomorrow – don't waste time on experiments. Click here, check our offer, and leave it to the professionals. Your time as a business owner is worth much more.
And if you're learning as a hobby or thinking about an IT career – take a look at the list below!
1. freeCodeCamp
freeCodeCamp is a huge community and platform offering thousands of hours of interactive coding courses. It focuses on web technologies (HTML, CSS, JavaScript, React), as well as Python and data analytics. Completing projects helps you earn free certificates that employers recognize.
2. Codecademy
A great place to start. Codecademy provides an interactive environment where you write code directly in your browser and see results instantly. You'll find free basics in Python, JavaScript, Java, and SQL.
3. The Odin Project
If you take programming seriously, this is a must. The Odin Project is a free, open full-stack web development curriculum. It won't hold your hand – it teaches you to set up your own environment and work with real code, preparing you for day-to-day IT work (React, Node.js, Ruby on Rails).
4. Artificial Intelligence: Claude / ChatGPT
In 2026, learning to code without AI is a mistake. Instead of searching forums for answers, use free versions of models such as Claude (from Anthropic) or ChatGPT. You can paste your non-working code and ask: "Act like a programming teacher. Don't give me a ready-made solution – explain why this code doesn't work and point me to the bug".
5. Cursor (AI code editor)
Cursor is currently one of the most popular code editors (based on VS Code) with built-in artificial intelligence. It offers a free plan, so you can learn to write code much faster, while seeing how AI suggests best practices in real time.
🛑 Alternative: What if you just want to edit your company website yourself?
Many entrepreneurs try to learn HTML and CSS only so they can manage the content on their site on their own. Instead of spending months on it, consider building a site based on Concrete CMS.
We’ll handle the hard technical part (coding and optimization), and you’ll be able to change texts and photos on the site using a “drag and drop” method – without knowing even a single line of code. Contact us.
6. Scrimba
Scrimba is a revolution in learning front-end. Instead of watching regular videos, you watch code written by an instructor, but at any moment you can pause, click the code on the screen, and edit it yourself! Their free course for HTML, CSS, and React is an absolute hit.
7. Coursera
Coursera works with universities (e.g., Stanford) and technology companies worldwide. For free, you can take a so-called course audit. You'll learn more advanced concepts like algorithms, data structures, and C++.
8. Udemy
Udemy is a platform with a huge library of video courses. While it’s known for paid materials (which you can often catch during big promotions), it also has a rich selection of fully free, multi-hour courses – perfect for a weekend start.
9. W3Schools
A classic that keeps getting better over the years. W3Schools isn't a typical course, but more of a “cheat sheet” and documentation. You'll find clear explanations for every command in HTML, CSS, JavaScript, or PHP, along with a “Try it yourself” button that lets you test the code in the browser.
10. SoloLearn
If you travel a lot and want to learn on the train or bus, SoloLearn is a great mobile app. It offers courses in the form of short, engaging lessons and quizzes (microlearning), helping you absorb knowledge in small chunks.
11. YouTube (Tech channels)
Don't forget the world's largest free video knowledge base. Channels like Traversy Media, Fireship, or the Polish Pasja informatyki offer free, multi-hour crash courses on virtually any technology – from building simple websites to complex server-side applications.
12. GitHub
Understanding GitHub is key to an IT career. While it's a platform for hosting code, it's also a valuable learning resource. You can browse open-source code written by senior developers, learn best practices, and slowly join community projects.
Summary: It's time for your move!
Starting to learn programming has never been easier or cheaper – especially with today's AI tools. Choose the platform that fits you best (we recommend starting with freeCodeCamp or Scrimba) and stay consistent. Just remember: theory is one thing, but building a stable, fast, and secure project from scratch is a completely different story.
