Codex offers one coding agent across the terminal, supported IDEs, a desktop app, and the web, with local CLI installs for major desktop platforms and ChatGPT-plan sign-in.
Codex CLI is an **Apache-2.0** coding agent that runs locally. It also has IDE support for VS Code, Cursor, and Windsurf, plus desktop and cloud-based Codex experiences.
Choose the surface that matches the task: terminal for repository work, IDE for in-editor use, app for desktop workflows, or web for a hosted agent. CLI installation supports **macOS, Linux, and Windows**.

Choose the surface that matches the task: terminal for repository work, IDE for in-editor use, app for desktop workflows, or web for a hosted agent. CLI installation supports **macOS, Linux, and Windows**. ChatGPT sign-in covers listed Plus, Pro, Business, Edu, and Enterprise plans. API-key use needs additional setup, and the material does not compare capabilities or isolation across the four surfaces.
Codex consolidates local terminal, editor, desktop, and hosted access around one coding-agent project and sign-in path, making surface choice a workflow decision rather than a separate-tool adoption. It also defines a base that monitoring, orchestration, mobile steering, and cross-agent plugins can extend, while leaving capability and isolation differences between surfaces unresolved.
