OpenAI Brings Codex to Windows With Native Sandboxing
OpenAI's dedicated Codex coding app lands on Windows with PowerShell support, one month after its macOS debut.
OpenAI just shipped its Codex coding app for Windows. The dedicated desktop tool arrives with native sandboxing and PowerShell developer environment support, expanding beyond the macOS version that launched a month prior.
The move gives Windows developers a first-class Codex experience rather than forcing them through the browser. Native sandboxing means code execution happens in an isolated environment — a critical feature for developers testing AI-generated code they don't fully trust yet.
OpenAI has been steadily beefing up Codex's capabilities. Back in early February, the company upgraded the app with the ability to manage multiple AI agents simultaneously, turning it into more of a multi-tasking coding command center.
The Windows launch signals OpenAI is serious about owning the developer tooling layer across platforms, not just the API business.
