## Verdict

They are the two reference agents and the choice usually comes down to what you already pay for: Claude Code ships with Claude plans and Codex with ChatGPT plans. On judgment over long tasks and large codebases, Claude Code holds the stronger reputation. Codex answers with cloud agents, convenient for launching several tasks in parallel and reviewing them as proposals.

## Side by side

| | Claude Code | OpenAI Codex |
|---|---|---|
| Rating | 4.4/5 | 4.1/5 |
| Price | From $17 USD | From $20 USD |
| Free trial | No | No |
| Platforms | Web, macOS, Windows | Web, macOS, Windows |
| Best for | Developers who want to delegate whole tasks, not just autocomplete lines. | Teams already paying for ChatGPT who want coding agents at no extra cost. |

## Claude Code

Claude Code is the reference among coding agents: you describe the task and it works alone on your repository, reading, editing and running until done. Its strength is serious work on real codebases, where the model's judgment and context handling make the difference. It ships inside Claude's paid plans, and the Pro plan's usage limits show on intensive days.

## OpenAI Codex

Codex is OpenAI's play for the same ground as Claude Code, with one distinctive card: cloud agents that let you launch several tasks in parallel and review them as change proposals. It ships inside ChatGPT's paid plans, so for anyone already paying that subscription the marginal cost is zero. The agent's judgment on long tasks remains the ground where these products get compared hardest.

## Frequently asked questions

### Which is cheaper?

In practice they tie: both ship inside subscriptions from about $17-20 a month (Claude Pro and ChatGPT Plus). The real cost appears under intensive use, where each plan's limits and the jump to higher tiers set the bill.

### Which works better on its own?

On long, ambiguous tasks over real repositories, Claude Code holds the more consistent reputation. On bounded, parallel tasks, Codex's cloud agents are especially convenient.

### Can I use both?

It is a common combination: same repository, each agent for what it does best. Both have CLIs and fit the workflow without getting in each other's way.
