Claude Code vs Cursor vs OpenAI Codex

Short answer

Claude Code and OpenAI Codex are terminal-first coding agents bundled with chat subscriptions: Claude Code with every paid Claude plan (Pro from $20 a month) and Codex with ChatGPT Plus, Pro, Business, Edu and Enterprise. Cursor is a separate AI-first editor at $20 a month for individuals.

Choose by where you work: the terminal and git (Claude Code or Codex) or a visual editor (Cursor). If you already pay for Claude or ChatGPT, try the bundled agent first.

Cost in practice

Bundled agents share limits with the chat plan they come with. Long agent sessions use far more capacity than chat, so heavy users of Claude Code commonly move from Pro ($20) to Max (from $100). Cursor's paid tiers above Individual (Pro+ and Ultra) exist for the same reason. We could not confirm current ChatGPT plan prices, so Codex's effective price is not shown.

Benchmarks

Evidence: Claimed by provider

Vendors publish agent benchmarks (for example, Anthropic reports Sonnet 5.5 at 70.6% on Terminal-Bench 4.0), but these are vendor claims and different vendors choose different benchmarks. We have not run our own tests. The best test is a week of real tickets from your own repository.

Safety checklist for coding agents

  • Run agents on a branch, never directly on main.
  • Require tests to pass and read the diff before merging.
  • Keep secrets out of the repository and the agent's environment.
  • Limit network and shell permissions where the tool allows it.

Common questions

Is Claude Code better than Cursor?

They suit different workflows. Claude Code is a terminal agent included with paid Claude plans; Cursor is an AI-first editor. Developers who live in the terminal tend to prefer Claude Code or Codex; those who want visual diffs prefer Cursor.

Do I need to pay separately for Codex?

Not if you have ChatGPT Plus, Pro, Business, Edu or Enterprise: OpenAI's Codex repository says you can sign in with those plans. You can also use an API key and pay per use.

Which coding agent is free?

Gemini CLI has a free tier of 60 requests a minute and 1,000 a day with a personal Google account. Cursor's Hobby plan is free with limited agent requests.
