Who should choose what?
Claude Code suits shell-native developers who want explicit repository instructions and command control. Codex is worth evaluating when your team already uses OpenAI's coding workflow and wants an agent profile aligned with that ecosystem.
Pick based on integration and control requirements, not the vendor name: run both on the same issue and keep the change that is easiest to inspect and reproduce.
Decision criteria
- Terminal and CI integration
- Instruction files, plan visibility, and approval gates
- Existing account, identity, and repository integrations
- Data handling and whether sensitive code may leave your environment
Workflow fit
Give each tool a bounded bug or refactor, with tests and acceptance criteria. Ask for a plan before edits, deny unnecessary network or destructive commands, and compare the final diff plus test output.
Tradeoffs
Claude Code's profile lists terminal workflow, hooks, MCP, and CI automation. OpenAI Codex's catalog entry should be checked for the exact current surfaces before adoption; avoid assuming feature parity from the shared agent label.
Privacy and control
Use only the official vendor pages linked in the profiles to confirm current training, retention, workspace, and enterprise controls. Keep secrets out of prompts and use a disposable branch during evaluation.

Frequently asked questions
Is one objectively more capable?
The catalog does not establish a controlled benchmark. Capability varies by repository, model access, and task framing, so use a repeatable internal test.
Where should I check pricing?
Use each profile's official source link and verify current prices and usage terms; they change.
