OpenAI has released the Codex desktop app for Windows, following its macOS launch last month. The app provides a dedicated environment for managing multiple coding agents, running tasks in parallel, and coordinating long-running projects.
Key Features: Codex desktop app
- Parallel Agents: Execute multiple coding agents simultaneously to handle different tasks within the same project.
- Isolated Workspaces: Each task operates in its own worktree to prevent conflicts and keep changes organized.
- Review Changes: Inspect diffs and proposed edits in a single interface before applying them to the codebase.
- Task Continuity: Switch between projects and tasks without losing context or progress.
- Workflow Automation: Create reusable skills to manage repeatable or scheduled tasks.
- Integration with Tools: Open changes directly in editors and maintain existing development setups.
- Progress Tracking: Monitor the real-time activity of each agent.
- Windows Sandbox: Agents run inside an OS-level sandbox with restricted tokens, filesystem ACLs, and dedicated sandbox users; escalation requires explicit approval.
Windows-Specific Enhancements
The Windows version introduces a native agent sandbox, enabling secure execution of agents in standard Windows developer environments such as PowerShell. It preserves configuration and history from the Codex CLI and IDE extensions, supporting seamless workflows.
Availability and System Requirements
- Platform: Windows PC
- Operating System: Windows 10 version 19041.0 or higher
- Access: Available via Microsoft Store or OpenAI Codex
- Sign-In: Requires a ChatGPT subscription or API key
The Codex app on Windows allows developers to coordinate agent-driven coding tasks, manage long-running projects, and maintain isolated workspaces in a secure environment.
