Description
Mastery is achieved through embracing challenges. Enhance your abilities by collaborating with peers on authentic coding tasks. Push your limits with kata designed by the community to develop various competencies. Become proficient in your preferred programming language or broaden your knowledge by exploring new ones. Tackle the kata in your unique coding style directly in the browser, utilizing test cases (TDD) to validate your progress. Reassess your methods with fresh, inventive, and optimized techniques. Kata are categorized by difficulty levels. As you conquer more challenging kata, you elevate your rank, allowing us to present you with suitable challenges. After each kata, compare your solutions with those of others to deepen your understanding. Engage in discussions about the kata, explore best practices, and share innovative techniques with fellow coders. Create kata that align with your passions and focus on developing specific skill sets. Inspire the community with your insights and coding expertise, fostering a collaborative environment for growth. Through these interactions, not only do you enhance your skills, but you also contribute to a thriving community of learners.
Description
Anyone can get an AI agent to turn tests green on a toy problem. kodwai measures the part that is harder to fake: how well you direct it. Developers pick a real engineering challenge (a CRDT text buffer, an event-sourced ledger, a zero-downtime migration), pull it down with npx @kodwai/cli@latest challenge <slug>, and solve it locally with Claude Code, Cursor or Codex. No browser sandbox. When they run npx @kodwai/cli@latest submit, kodwai reads the session (prompts, commits, test runs) and returns a 0 to 100 score across three axes: Direction (how you steer, verify and decompose), Outcome (what shipped, replayed and stress-tested) and Lift (how far you beat a solo AI). Each signal cites its evidence, and the score comes with a confidence interval instead of false precision. Developers get 3 free scored submissions, then connect their own Anthropic key for unlimited runs. Teams can use the hiring track to run private real-world interviews.
