Claude Code vs Codex: which is better?

It depends on your code and how you work, so this page doesn’t pick one. Both read code, edit files and run commands; they differ in plans, limits and where they run. Give both the same real task and compare the fix, the time you spent checking it and the usage it took.

Is Codex cheaper than Claude Code?

Not in general. ChatGPT Plus and Claude Pro are both $20 a month, with different usage included. Codex on Free and Go, the higher plans and pay-as-you-go billing can each change the answer for you.

Does either plan mean unlimited coding?

No. Both have usage limits. Claude Ultra and OpenAI’s Pro plans have no five-hour limit, but weekly limits still apply.

Can I use Claude Code and Codex together?

Yes. Both can read an AGENTS.md file in the repository (Claude Code reads it in place of CLAUDE.md), so one file of project rules can serve both. For briefs and reports, both can read and update the same files in 1folder. Neither sees the other’s session.

Claude Code vs Codex: compare the workflow, then try your task

Short answer

Claude Code and Codex both read a codebase, edit files and run commands, in the terminal, an editor or the browser. Both come with a $20 monthly plan: Claude Pro and ChatGPT Plus. Neither is better for every team, so run the same real task in both and compare the fix, your review time and the usage it took. Both can share notes and handoffs in 1folder.

Which to pick

Pick Claude Code if

You already pay for Claude Pro, Max or Ultra: Claude Code comes with it.
You need more than Pro’s usage: Max is $100 a month, Ultra $200 with no five-hour limit for verified accounts.
On your own repository, its fixes are the ones you understand, can check and want to keep.

Pick Codex if

You already pay for ChatGPT Plus or Pro: Codex comes with it, on the web, CLI, IDE extension and iOS.
You want to try it before paying: OpenAI lists light Codex use on Free and Go in the desktop app, subject to rollout.
On the same test, its fixes are the ones you understand, can check and want to keep.

Claude Code vs Codex pricing: compare access, not just a price

For one person paying monthly, Claude Pro and ChatGPT Plus are both $20, and each includes its coding tool. Claude Pro is also $200 a year paid up front. The same price doesn’t buy the same amount of coding: each plan has its own usage limits.

Above that, Claude lists Max at $100 and Ultra at $200 a month; OpenAI lists Pro at $100, $200 or $500 a month. OpenAI also lists Codex on Free and Go for light coding in the desktop app, subject to rollout, without the other places Plus gets.

Both companies also offer pay-as-you-go billing by usage, which works differently from a subscription. Compare the way you’ll actually sign in and pay. Prices change often; check the linked pages before you buy.

Claude Code vs Codex usage limits are not fixed tasks per month

Claude’s pricing page describes a five-hour limit and a weekly limit. Max gives five times Pro’s usage. Ultra gives ten times Pro’s weekly usage and, for verified accounts, no five-hour limit. In Claude Code, /usage shows how much you have left.

OpenAI gives estimates of local messages per five hours for Plus, says Pro plans currently have no five-hour limit, and says weekly limits may also apply. It states that the estimates are not fixed message limits. The usage dashboard, or /status in Codex CLI, shows your own account.

So neither plan converts into “bugs fixed a month”. A one-line fix and a long debugging session are different jobs. In a trial, note for each tool whether the fix worked, how long you spent checking it and how much usage it took.

Give both tools the same test

In Claude Code
“Read CLAUDE.md first. Find why an empty search query produces no results. Explain the cause, add a regression test and make the smallest fix. Run the relevant tests. Report changed files, evidence and remaining risks.”
In Codex
“Read AGENTS.md first. Find why an empty search query produces no results. Explain the cause, add a regression test and make the smallest fix. Run the relevant tests. Report changed files, evidence and remaining risks.”

Judge the result on your repository

Start each tool from its own copy of the same commit, with the same request.
Check that the cause it names really explains the bug. A confident explanation isn’t evidence.
Look for unrelated changes in the patch, and check that the new test fails without the fix.
Run the checks yourself and note how long you spent reviewing or correcting each result.

Use both on the same briefs and reports in 1folder

Save the reviewed handover
After connecting Claude Code and Codex to the same 1folder folder, ask Claude Code: “Save Search fix report in 1folder with the cause, changed files, tests run and open risks.” Keep application code in your normal repository.
