OpenAI has released a dedicated Codex app for macOS, giving developers a focused workspace for agent-based coding. The app brings Codex into a standalone Mac experience designed to work smoothly with IDEs and the Terminal.
In a separate announcement, OpenAI said the Codex Mac app acts as a central hub where multiple coding agents can run at the same time. Each agent works in its own thread, grouped by project, which makes it easy to switch tasks without losing context.
How the Codex Mac app works
The app lets you review an agent’s code changes directly in the thread. You can comment on diffs or open them in your editor for manual edits. Built-in support for worktrees allows several agents to work on the same repository without conflicts, since each agent uses an isolated copy of the code.
OpenAI explained:
“The Codex app provides a focused space for multi-tasking with agents,” the company said.
The app also syncs session history and settings from the Codex CLI and IDE extensions. As a result, you can pick up existing projects right away without extra setup.
Automations and availability
Codex for Mac includes Automations, which let agents run in the background on a schedule you define. When an automation finishes, its output appears in a review queue so you can continue work when ready.
To mark the launch, OpenAI is temporarily expanding access. The Codex app is available to ChatGPT Free and Go users, while rate limits are doubled for Plus, Pro, Business, Enterprise, and Edu users for a limited time.
You can download the Codex macOS app directly from OpenAI’s website, with a detailed blog post available for those who want deeper technical information.
