About kodwai is a platform where developers solve real coding challenges on their own machine with their own AI coding agent (Claude Code, Cursor, or Codex) and get scored on how well they direct the agent, across three axes: Direction, Outcome, and Lift. Pick a ticket-sized challenge (a multi-tenant rate limiter, an idempotent ETL pipeline, a Raft-lite log), run npx @kodwai/cli@latest challenge <slug> to pull the problem, starter code and tests into a fresh git repo, solve it the way you actually work, then run npx @kodwai/cli@latest submit. The score is 0 to 100, and every signal cites evidence from your transcript, commits and test runs. Free for developers with a public profile and leaderboard. Hiring teams can run private real-world interviews and see how candidates work with AI agents: the prompts, the recovery, the verification, the result.

Pros & Cons from Real Users Pros Cool Platform, features were helpful. I liked the product for the week or two that I managed to use it. 1. LeetCode helps in preparing for competitive codings in a gradual manner. 2. The questions are crafted in a way that it teaches fundamental concepts as well as problem-solving. 3. The question helps in understanding all the concepts of Data Structures and Algorithms to crack any interview. - It is one of the best sites to practice competitive coding. - It supports multiple languages like Java, C, C++. - It has a great community to help you if you get stuck at any question. I super love the Solution and Discuss. Systematic knowledge is more important than just crack the problems, which I can learn from Solution. And I see so many brilliant ideas from Discuss. Cons Took a week and a half to respond to a request to cancel my $35/month account, only to refuse to do it on their end. They provided instructions to find the cancellation in their interface; it was so well hidden that it was nearly unfindable without the instructions. 1. I have been using LeetCode to polish my coding skills from a long time, and I haven't found any con with the platform or with the method of teaching so far. - No con whatsoever, Leet Code is a great platform that provides value for your money. I wish it has lifetime membership and I will definitely and seriously consider about it.

Categories Coding Challenge Supported Interview Preparation Supported Technical Skills Development Supported	Categories Coding Challenge Supported kodwai is a coding challenge platform built for agentic coding. Challenges are realistic, ticket-sized tasks (from a bookshelf REST API to a Raft-lite log) and each one hides a few traps that a single prompt tends to miss. You solve them locally with your own AI coding agent, and the score reflects how well you directed it, not just whether the tests passed: Direction, Outcome and Lift, from 0 to 100, with evidence for every signal. There is a public leaderboard, a Direction rating that moves with every scored run, and a weekly league.
