7 Free Websites to Improve Your Coding Skills

7 websites that made me a better developer — and they're all free. I've been coding for years and these platforms are still open in my browser regularly. Whether you're just starting out or sharpening your skills between projects — bookmark this list. #1 ⚡ LeetCode [DSA · Interviews] The gold standard for interview prep. 2,500+ problems across arrays, trees, graphs, and dynamic programming. If you're targeting FAANG or any product company — this is non-negotiable. #2 🏆 HackerRank [Skills · Certification] Great for structured skill tracks and official certifications employers actually recognise. Strong for SQL, Python, and problem-solving challenges. Perfect if you're building a verifiable portfolio. #3 ⚔️ CodeWars [Daily Practice · Katas] Gamified daily coding challenges called "katas" — ranked by difficulty. Addictive in the best way. Brilliant for keeping your problem-solving sharp without the pressure of interview simulation. #4 🧠 GeeksforGeeks [Reference · Learning] The developer's encyclopedia. Every algorithm, data structure, and concept explained with examples and code. I still open GFG when I need a clean explanation of something I haven't touched in months. #5 🆓 freeCodeCamp [Beginners · Full Curriculum] A complete free coding curriculum from HTML basics to APIs, data visualisation, and machine learning. Over 10,000 hours of content. The best structured starting point for anyone new to development. #6 👨🍳 CodeChef [Competitive · Contests] Monthly contests, division-based rankings, and a strong competitive programming community. Excellent for building speed and accuracy under timed pressure — the skill that actually matters in live interviews. #7 🎯 Exercism [Mentorship · Deep Learning] The most underrated on this list. Solve exercises in 65+ programming languages and get real feedback from human mentors. If you want to truly understand a language — not just use it — start here. --- The developers who consistently level up aren't the ones with the most expensive courses. They're the ones who show up daily on platforms like these — one problem at a time. Which one is your go-to?
