The short answer

LeetCode is for developers drilling algorithm puzzles for technical interviews, with company-tagged questions and mock interviews in Premium. CodeChef is for students moving from learning a language into competitive programming, with structured courses, an AI mentor and rated contests. The core difference: LeetCode is interview prep, CodeChef is a learn-then-compete path.

CodeChef or LeetCode: our take

Both sites give you problems, an in-browser editor that runs your code against tests, and rated contests. Their goals differ. LeetCode is built around technical interview preparation: a large library of data structure and algorithm problems, plus SQL and shell questions, tagged by topic and difficulty, with community threads collecting alternative solutions. CodeChef combines contests with structured courses in Python, Java, C++, C, SQL, React and DSA, each made of short lessons and practice problems, with certificates and an AI mentor for hints.

For beginners, CodeChef offers more guidance. Its learning paths start from the basics, while LeetCode assumes you can already program and drills interview-style puzzles, so newcomers usually pair it with a course. For interview candidates, LeetCode is more targeted: Premium adds locked questions, official write-ups, filtering by the companies that asked a question, mock interviews and faster judging.

Contests run on both. LeetCode holds weekly and biweekly contests with a public rating. CodeChef runs rated contests with a star system and says over 5M developers use the site, though its top-level contests draw fewer elite competitors than Codeforces. Pricing follows a similar freemium shape: practice problems and contests are free on both, LeetCode Premium is billed monthly or annually, and CodeChef Pro unlocks premium courses with a free trial of premium content. CodeChef shows more upsell prompts around the site. LeetCode also has iOS and Android apps, while CodeChef is web only.

Pick LeetCode if you are preparing for algorithm-heavy interviews at tech companies and want to practise the exact style of questions they ask. Pick CodeChef if you are still learning a language or DSA and want lessons, hints and contests in one place. Many students use CodeChef to build fundamentals, then switch to LeetCode when interviews approach.

Free weekly and biweekly contests with a public rating

What is CodeChef?

CodeChef is a coding practice platform from India that combines competitive programming contests with structured courses. Learners follow paths in Python, Java, C++, C, SQL, React and data structures and algorithms, each built from short lessons and hundreds of practice problems, and can earn certificates. Its weekly contests are rated with a star system, and a built-in browser compiler lets you code, test and debug without installing anything; an AI mentor helps when you're stuck. Practice problems and contests are free, and a Pro subscription unlocks premium courses and extra help, with a free trial of premium content. The site says over 5 million developers use it. It sits between Codeforces, which is purely contest-focused, and course sites like Codecademy, so it suits students moving from learning a language to their first contests; experienced competitors often find its top contests less active than Codeforces.

What is LeetCode?

LeetCode is the site most software engineers end up on when they start preparing for technical interviews. It hosts a large library of data structure and algorithm problems, plus SQL and shell questions, each with a browser code editor that runs your solution against hidden test cases and reports whether it passed. Problems are tagged by topic and difficulty, and community discussion threads collect alternative solutions. Weekly and biweekly contests give a rating that tracks progress over time. The free account covers most problems, contests and community solutions. Premium, sold as a monthly or annual subscription, adds locked questions, official write-ups, filtering by the companies that asked a question, mock interviews and faster judging. It runs on the web with mobile apps for reading and practising. The focus is narrow: it drills interview-style puzzles rather than teaching programming from scratch, so beginners usually pair it with a course.
