Claude Code vs OpenAI Codex
Updated · prices checked on vendor pages
Short answer: Both are agentic coders that work in your terminal and editor. Claude Code is our #1 for multi-file work across a repo, and it needs a paid Claude plan (Pro $20/mo). OpenAI Codex is included in every ChatGPT plan, including Free with limited usage, so it is the cheaper way to try an agent. If you already pay for one of the two, start with the one you have.

Verdict
- Pick Claude Code if you delegate large, multi-file features and want the strongest results.
- Pick OpenAI Codex if you already have ChatGPT, want cloud tasks that run while you are away, or want to start for $0.
Both bill against usage limits that reset on a rolling window. Heavy users hit them, so check the limits for your plan.
