Which to pick
Our advice: pick Claude Code if you want Claude's models writing your code. Pick ChatGPT if you want chat and a coding agent on one plan, or want to start free. Both use MCP servers.
The main limit on each side: Claude Code has no free plan, and Codex in ChatGPT uses OpenAI's GPT-6 models, not Claude.
Best for

- Claude Code: terminal, VS Code, JetBrains, desktop and browser users
- ChatGPT: anyone who also wants a general chat assistant on the same plan
- ChatGPT: people who want to try a coding agent on a free plan
Skip it if
- Claude Code: you need a free plan, since it starts at Pro
- ChatGPT: you want Claude models, since Codex on a ChatGPT plan lists GPT-6 models
Questions
Is Claude Code better than ChatGPT for coding?
Neither vendor publishes a head-to-head test, so no one can say for certain. Claude Code is built only for coding. ChatGPT is a chat assistant whose coding agent is Codex. Both have a $20 plan, so the cheapest test is to give the same task to each for a week.
What is the difference between Claude Code and ChatGPT?
Claude Code is a coding agent that reads your project, edits files and runs commands, in the terminal, an editor, a desktop app or the browser. ChatGPT is OpenAI's general chat assistant, and Codex is its coding agent, included in every ChatGPT plan.
How much do Claude Code and ChatGPT cost?
Claude Code comes with Claude Pro at $20 a month ($17 a month billed yearly), Max at $100 and Ultra at $200. ChatGPT is $0 on Free, $8 on Go and $20 on Plus, with Pro plans at $100, $200 or $500 (all as of November 2026).
Can I use Claude Code for free?
No. The Claude Free plan does not include Claude Code. You need Pro or higher, or an Anthropic Console account that pays per token.
Does ChatGPT have a free coding agent?
Partly. ChatGPT Free and Go include Codex with the GPT-6 Luna model in the desktop app, subject to rollout. Codex in the terminal, the editor extension, the web and iOS starts with Plus.
Can I use Claude Code with a ChatGPT subscription?
No, a ChatGPT login does not work in Claude Code. Most Claude Code surfaces need a Claude subscription or an Anthropic Console account, and Claude Code can also run on models from Amazon Bedrock or Google Cloud. A ChatGPT plan gives you Codex instead.
Do Claude Code and ChatGPT both support MCP?
Yes. Claude Code connects to MCP servers, and ChatGPT and Codex do too, so many of the same servers work in both.
Which one has higher usage limits?
Both use usage limits that reset on a schedule, and both vendors say real use varies with the task. Claude Max gives 5 times Pro usage, and Ultra has no 5-hour limit. ChatGPT Pro plans have no five-hour limit, and Plus is estimated at 15 to 160 GPT-6.1 Sol messages per five hours (as of November 2026).
Is ChatGPT Codex the same as Claude Code?
No, they are rival products from different companies. They do the same kind of job. See Claude Code vs Codex for the direct comparison.
