Overview
Codex CLI is a coding agent from OpenAI that runs in the terminal on your machine. It installs through a shell script, npm, Homebrew, or prebuilt release binaries for macOS and Linux, and it signs in with a ChatGPT plan or an API key. The same project also covers IDE extensions and a desktop app.
Who it is for: Developers who want a terminal coding agent tied to OpenAI
Strengths

- Multiple install paths: script, npm, Homebrew, or release archive
- Sign-in with an existing ChatGPT Plus, Pro, Business, Edu, or Enterprise plan
- Apache-2.0 license, written in Rust
Weaknesses
- README documents only OpenAI sign-in or API key; other model providers are not mentioned
- API key use requires extra setup beyond the quickstart
- RAM and disk requirements are unknown
- Install scripts fetch from OpenAI-hosted release URLs by default
