OpenAI has launched a new Codex app for macOS, a new interface designed to make working with AI coding agents easier, faster, and more collaborative. The app allows developers to manage multiple agents at once, run tasks in parallel, and oversee long-running projects, changing how software is built.
Since its debut in April 2025, Codex has enabled developers to handle complex tasks from start to finish. The new macOS app acts as a central command centre, providing a workspace to supervise multiple AI agents, review their work, and collaborate more efficiently than traditional IDEs or terminal tools allow.

The Codex app lets developers work with multiple agents simultaneously, each running in separate threads organised by project. Users can switch between tasks without losing context, review code changes, comment on diffs, and open files in their preferred editor for manual adjustments. This setup ensures developers remain fully in control while agents handle routine coding work.
To prevent conflicts when multiple agents work on the same repository, the app includes support for worktrees, providing each agent with an isolated copy of the code. Developers can explore different approaches without worrying about breaking the main project. They can review changes locally or let agents continue progressing independently.
The app includes a library of skills for tools and workflows that have become popular at OpenAI. Developers can convert Figma designs into production-ready UI code, manage bugs and releases in Linear, deploy apps to popular cloud platforms, generate images for UI mockups and product visuals, reference OpenAI API documentation, and create or edit PDFs, spreadsheets, and docx files.

The Codex macOS app is now available. Users with a ChatGPT Plus, Pro, Business, Enterprise or Edu subscription can use Codex across the CLI, web, IDE-extension and app with their ChatGPT login. For a limited time, ChatGPT Free and Go users can access Codex as well. OpenAI is also temporarily doubling rate limits for all paid plans.
