CodeChef
Learn and practice coding with problems
CodeChef is an online coding platform for learning to code, practicing programming problems, and taking part in coding competitions. It addresses the need for structured practice alongside theory, offering interactive courses in Python, C, C++, Java, and JavaScript, plus thousands of practice problems covering programming languages, data structures, algorithms, SQL, and web development. Problems range from beginner-level exercises to complex mathematical challenges.
Core features include structured roadmaps combining learning and practice paths, skill tests, weekly programming contests, and a public profile for sharing certificates, test scores, and contest ratings. An AI Mentor provides step-by-step explanations and debugging help, while a built-in browser compiler supports coding and testing across many languages, including HTML and React. Courses cover topics such as DSA, backend development, data analysis, and machine learning, with certificates issued on completion.
CodeChef Pro is a subscription plan granting unlimited access to premium content and features, including hints, video solutions, AI help, and debugging tools. Courses can be previewed for free, though completing a course and earning a certificate requires Pro.
