Description

Repetition leads to mastery, and the Showcode challenges provide an excellent platform for experiential learning. If a challenge does not yield the desired outcome, you have the chance to revisit and refine your skills afterward. As you progress, you can accumulate a portfolio filled with achievements, badges, and certificates that highlight your growth. This profile can then be shared with potential employers, showcasing your coding skills as a testament to your abilities rather than solely relying on traditional qualifications or past experiences. With 84 teams competing in 6 different leagues, the competition is intense as they vie for points in a head-to-head format. By signing up, you not only have the chance to win exciting prizes but also to gain exposure to leading brands. Participants will tackle a total of 13 challenges, each estimated to take around an hour to complete, with every challenge remaining open for 2 weeks and only the initial submission contributing to the score. Individual coders earn points for their University by successfully completing these challenges, and the team that accumulates the highest points based on the best 10 individual scores claims victory in the fixture, earning 3 valuable points. The ultimate showdown occurs in the Unicode 20/21 Grand Finale, where the top 10 coders from the 5 leading teams in each league compete fiercely for the championship title. This thrilling finale not only highlights the best talent but also fosters a sense of community and collaboration among participants.

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.

Coding Challenge

Kodwai is an innovative platform designed for hands-on coding challenges that emphasize agency in coding. The challenges presented are practical, bite-sized tasks—ranging from creating a bookshelf REST API to implementing a simplified version of the Raft consensus algorithm—and each task incorporates subtle pitfalls that a simple prompt might overlook. Participants tackle these challenges locally using their own AI coding agents, and the scoring system evaluates not only the success of the tests but also how effectively the user guided their agent. Scores are based on three criteria: Direction, Outcome, and Lift, with a scale from 0 to 100 and detailed evidence for each metric. The platform features a public leaderboard, a dynamic Direction rating that updates with each scored attempt, and weekly competitions to foster a sense of community.
