About

About Codewars

Codewars teaches programming through "kata" — bite-sized coding challenges ranked by difficulty that you solve in the browser with instant test feedback. After passing a kata you can compare your code against thousands of community solutions to learn different approaches.

Capabilities

Key Features

Ranked kata challenges.

Thousands of community-authored problems are graded from 8 kyu (beginner) to 1 kyu (expert), so you progress through steadily harder exercises and earn rank as you go.

In-browser test-driven solving.

You write code directly in the editor against a prepared test suite in 55+ languages including Python, JavaScript, Java, C#, Rust, and Go, getting immediate pass/fail feedback.

Community solution comparison.

Once you solve a kata you can read and vote on other users' solutions, a practical way to see alternative patterns and idiomatic code for the same problem.
