What is kodwai AI?
kodwai is an agentic coding challenge platform where developers solve realistic software engineering tasks on their own machines using AI coding agents such as Claude Code, Cursor, or Codex. Instead of testing only the final code, kodwai evaluates how effectively developers direct the AI agent, including planning, specification, verification, decomposition, recovery, code quality, testing, and handling hidden edge cases. Developers run challenges through the kodwai CLI, work in their preferred editor, and submit their code, test runs, commits, and agent transcript to receive a score and detailed feedback.

How you can use it
kodwai can be used by developers to practice working with AI coding agents on realistic software engineering tasks and understand how effectively they plan, prompt, test, verify, and correct an AI agent. It can also be used by companies and hiring teams to run practical coding interviews using real-world problems, observe the candidate's complete working process, evaluate sessions against custom rubrics, and compare candidates based on their demonstrated ability to work with AI coding tools.
Plans & pricing
kodwai's developer platform is free. Developers receive their first 3 scored submissions for free; after that, they can add their own Anthropic API key for unlimited runs. The platform also has a paid hiring product for companies, but public pricing is not currently listed. The company's published business plan describes planned hiring tiers, but these should not be entered as current prices because they are marked as planned.
