OpenAI Releases Codex App for Windows

One month after it released a standalone Codex app on the Mac, OpenAI announced a version for Windows. The company reports that the Mac app has been downloaded over one million times since its initial release.

“Codex is the best way to build and ship with agents, powered by OpenAI’s frontier coding models, and it’s now the only coding agent with a first-class Windows experience,” an OpenAI representative told me. “According to a 2025 survey from Stack Overflow, nearly 50% of developers use Windows for professional use and more than 55% use it for personal use.”

OpenAI says that its Codex app for Windows is built for real Windows developer environments and not just Windows compatibility. It provides native sandboxing and native workflows so that developers can stay in the tools and environments they already use without falling back to the Windows Subsystem for Linux (WSL) or virtual machines for safety reasons.

The Codex app for Windows lets developers command multiple agents working asynchronously across projects, delegate and schedule repeatable work using Automations, go beyond code generation using Skills that connect agents to tools and workflows, and review, guide, and intervene in agent work without losing context. It’s available for those on ChatGPT Free, Go, Plus, Pro, Business, Enterprise, and Edu accounts today and it can be used across the app, CLI, IDE extension, and cloud with a single account.
