Codex CLI is built for developers who already live in the terminal and want ChatGPT‑level reasoning plus the power to actually run code, manipulate files, and iterate – all under version control. In short, it’s chat‑driven development that understands and executes your repo.
- Zero setup — bring your OpenAI API key and it just works!
- Full auto-approval, while safe + secure by running network-disabled and directory-sandboxed
- Multimodal — pass in screenshots or diagrams to implement features ✨
And it's fully open-source so you can see and contribute to how it develops!
