The honest brief

Claude Code

Ships the same agent across CLI, IDE, desktop, and web — reads the spec, writes the diff, runs tests, opens the PR.

  • Strong autonomous multi-step coding
  • MCP and subagents support
  • Runs on API key or Pro/Max plan
  • Anthropic models only
  • Token usage can get expensive
  • Terminal-first learning curve

Codex

Backed by OpenAI's Codex-tuned models and integrated across CLI, IDE, web, and ChatGPT — one coding agent everywhere you work.

  • Local CLI, cloud, IDE, and ChatGPT
  • Cloud agent runs in isolated containers
  • Parallel cloud agent tasks
  • Cloud agent and models are proprietary
  • Best value needs a ChatGPT plan
  • Token-credit billing can surprise
  • Newer than rival coding agents
