Codex CLI - Open AI

Codex CLI is an open-source command-line tool that connects OpenAI’s Codex model with your terminal, allowing you to interact with code using plain language prompts and commands. You can use Codex CLI to explain codebases, fix bugs, add new features, refactor code, run tests, and automate repetitive tasks by simply typing what you want to do. It supports multimodal inputs, so you can attach screenshots or diagrams for code or error analysis right from the CLI. You can control how hands-on the agent is with approval modes—from suggesting edits for your confirmation to full automation—keeping your workflow flexible and secure. Codex CLI works entirely on your local machine, integrates with version control, and is compatible with advanced models like GPT-5-Codex and others via API, so your code never leaves your environment unless you choose to share it. It turns your terminal into a powerful AI coding assistant that speeds up development, debugging, and automation.
