Codewars
Code challenges for developers
Codewars is a coding practice platform where developers sharpen their skills by solving programming challenges called kata, ranked by difficulty from beginner (8 kyu) to expert (1 kyu). The platform supports 55+ programming languages with in-browser coding, test-driven feedback, and community-authored challenges. After solving a kata, users can compare their approach with thousands of community solutions, learning alternative patterns and techniques. Codewars also serves educators through classroom tools and companies through technical assessments powered by sister platform Qualified.
