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
