Claude Code vs OpenAI Codex

Both are coding agents you delegate tasks to. Claude Code works in your terminal, IDE or browser and is especially strong at understanding large codebases and iterating until tests pass. Codex runs tasks in cloud sandboxes connected to your repository and fits naturally if your team already pays for ChatGPT.
