Editor’s verdict

Claude Code runs locally in your terminal and editor, giving you full control over the coding loop; OpenAI Codex executes tasks in a cloud sandbox, enabling hands-off parallel execution. Choose Claude Code if you want an interactive agent you steer in real time; choose Codex if you prefer to fire off tasks and let them run in the background.
