Codex

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.

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 CODEXINSTALLERUSERELEASESOPENAICOM to false (0 and no are also accepted):
