The official Codex desktop app from OpenAI is your command center for agentic software development. With the Codex app you can: - Multi-task with agents — Run multiple coding agents in parallel, organized by project and thread - Keep work isolated — Built-in worktrees and cloud environments let agents make changes simultaneously without conflicts - Review before you merge — Inspect diffs in the thread, leave comments, and open changes in your editor - Stay in flow — Seamlessly switch between tasks and projects without losing context - Use skills — Extend Codex with reusable workflows that bundle tools, scripts, and team conventions - Automate repeat work — Delegate routine tasks with scheduled or repeatable workflows - Bring your setup — Picks up your history and configuration from the Codex CLI and IDE extension - Safer by default on Windows — Codex runs in a secure sandbox with bounded permissions, and only escalates when you approve it Download Codex and ship more, with less overhead.
