Codex app

Codex app for Windows

The Codex app is now available on Windows. The app gives you one interface for working across projects, running parallel agent threads, and reviewing results in one place.

The Codex app runs natively on Windows using PowerShell and a native Windows sandbox for bounded permissions, so you can use Codex on Windows without moving your workflow into WSL, onto a virtual machine, or by deactivating the sandbox.

The Windows app includes the same core features as the rest of the Codex app:

• Skills to discover and extend Codex capabilities.
• Automations to run work in the background.
• Worktrees to handle independent tasks in the same project.

If you prefer to develop in WSL, you can also switch the Codex agent and the integrated terminal to run there.

Download it from the Microsoft Store and sign in with your ChatGPT account or an API key. For setup and configuration details, see Setup, Use WSL with the Codex app, and Customize the app for your development setup.
