Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):
curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh
$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; irm https://chatgpt.com/codex/install.ps1 | iex
Codex CLI can also be installed via the following package managers:
## Install using npm
npm install -g @openai/codex
## Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
codex-aarch64-apple-darwin.tar.gzcodex-x86_64-apple-darwin.tar.gzcodex-x86_64-unknown-linux-musl.tar.gzcodex-aarch64-unknown-linux-musl.tar.gzEach archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.

For more advanced scripting, including how to parse JSON and handle errors, use
the --output-format json flag to get structured output:
gemini -p "Explain the architecture of this codebase" --output-format json
For real-time event streaming (useful for monitoring long-running operations),
use --output-format stream-json to get newline-delimited JSON events:
gemini -p "Run tests and deploy" --output-format stream-json
