We compare AI coding tools by asking them to help build the same small app: Snake in React. The session is a comparison, not a single production build, so the walkthrough follows the tool categories: chat applications, coding assistants and IDEs, project bootstrappers, and agents.

The comparison

The same app appears in several workflows:

The workshop code includes two Vite React projects. snake-chatgpt keeps the game in one component and is useful for seeing what a chat app can produce from a short prompt. snake-claude-code splits the page shell from the game component, adds score, start and restart flow, WASD controls, and a walls versus pass-through mode.
