OpenAI has launched the Codex app for macOS, positioning it as a desktop hub for supervising multiple coding agents across long-running tasks. Usage is included with paid ChatGPT plans and, for a limited time, is also available to ChatGPT Free and Go users. OpenAI states that paid plans receive doubled Codex rate limits during this period.
With the Codex app you can:

- Multitask effortlessly: Work with multiple agents in parallel and keep agent changes isolated with worktrees
- Create & use skills: package your tools + conventions into reusable capabilities

The work is divided into separate project threads, allowing tasks to run in parallel. The app includes built-in diff review, comments, and a handoff to your editor for manual edits. Git worktrees are supported, enabling multiple agents to work on the same repository in isolated copies to avoid conflicts. The app carries over session history and configuration from the Codex CLI and IDE extension. It also packages skills, instructions, scripts, and resources for repeatable workflows. Scheduled Automations run on a user-defined schedule and send results to a review queue.
Security is ensured through system-level sandboxing by default: agents are limited to the active folder or branch and cached web search. They must request permission for elevated actions like network access, with configurable rules to allow trusted commands. OpenAI reports that Codex usage has doubled since GPT-5.2-Codex was released in mid-December, with more than one million developers using Codex in the past month. A Windows release and cloud-triggered Automations are next on the agenda.
