CodeChef

CodeChef is a competitive programming contests platform that endeavours to empower learners to master coding through structured courses, practice problems, and regular contests. It offers entry-level paths in languages like Python, C++, and Java, along with advanced tracks in data structures, algorithms, and web development. For educational institutions, CodeChef provides integrated lab modules and mobile content-enabled courseware that can be embedded into lectures, labs, or homework assignments.

CodeChef competes with similar educational technology companies such as LeetCode, HackerRank, SPOJ, Topcoder, and GeeksforGeeks.
