Codex CLI

OpenAI

Freemium

Codex CLI is OpenAI's lightweight coding agent that runs locally in your terminal to write, edit, and execute code.

Local Terminal Agent: Runs on your own machine and edits files, executes shell commands, and iterates on tasks without leaving the terminal.
ChatGPT Plan Sign-In: Uses your existing ChatGPT Plus/Pro/Business/Edu/Enterprise subscription for auth, so you don't need a separate API key.
Approval-Gated Execution: Prompts you before running shell commands or file writes, giving you control over what the agent touches.
Cross-Platform Binaries: Ships prebuilt binaries for macOS (arm64/x86_64), Linux (x86_64/arm64), and Windows via multiple package managers.
Companion Products: Interoperates with Codex Web (chatgpt.com/codex), the Codex desktop app, and the Codex IDE extensions for VS Code, Cursor, and Windsurf.
Open Source Under Apache 2.0: Fully open source on GitHub so teams can inspect, fork, and self-host the CLI.
API Key Fallback: Optional OpenAI API key authentication for users outside a ChatGPT plan or for CI environments.

Terminal-native Pair Programming: Delegate refactors, bug fixes, and small features to Codex while staying in your existing shell workflow.
Test and Fix Loops: Have Codex run your test suite, read failures, and iterate on patches until green.
Repository Onboarding: Ask Codex to explore an unfamiliar codebase, summarize modules, and answer 'where is X handled' questions.
Shell and DevOps Automation: Draft and run shell scripts, containers, and CI recipes with an agent that can execute them locally.
Cross-Surface Continuation: Start a task in Codex Web or the Codex IDE extension and finish it from the terminal on the same ChatGPT account.
