OpenAI Adds a Linux Download for the Codex Desktop App in ChatGPT
- OpenAI's Codex page now includes a Linux download for Codex in ChatGPT, alongside its IDE extension and the
@openai/codexCLI package. - Codex in ChatGPT is presented as a coding-agent control app that can run agents in parallel across projects using built-in Git worktrees and cloud environments.
- The product lets teams define reusable Skills containing coding standards and workflows, which Codex applies across tasks with less supervision.
- OpenAI says users can schedule background work such as issue triage, alert monitoring, and CI/CD tasks.
- Codex uses the same ChatGPT account across the ChatGPT app, editor extension, and terminal, so work can move between those interfaces.
Hacker News opinions
I would not wait for a company that keeps intelligence behind a premium subscription and can change access by policy.
The landing page changes by OS. I got a Norwegian Windows download page, while the Linux installer link is on learn.chatgpt.com/docs/app.
If this is an Electron app, I do not see much difference from running Codex in the browser. My Chrome app on Mint looks identical.
The desktop app can access your computer, which a browser app generally cannot do in the same way.
For me, the GUI is easier to use than the CLI. Drag and drop, Markdown and image rendering, and normal text-field navigation reduce friction.
I expect the app's advantage is multi-agent supervision: isolated Git worktrees, terminals, file previews, PR review, SSH, an integrated browser, scheduling, and persistent task context.
The app also makes history easier to revisit than digging through CLI transcripts, and cross-device ChatGPT access could matter if I need to check work from my phone.
I worry that a desktop agent makes it too easy to give an unisolated tool access to a primary account, or even admin privileges. Too many people already skip isolation.
The Linux version appears to use bubblewrap and seccomp for a workspace sandbox by default, alongside automatic mode or user approval. I would still prefer a VM.
I installed it a few hours ago and it works fine in a Debian KVM guest over X11.
I treat coding agents as trojans and run them away from the rest of my system. A full desktop VM is fine, but I would not give one direct access to my main machine.
The app has sandboxing by default, and Codex itself is open source, so I do not think the trojan framing is the whole story.
I tested it on Windows and it created two users, then changed NTFS permissions on every file under my user directory without warning. SSH and several applications broke, and fixing roughly 10 million permissions took me three hours.
I doubt many Linux users need this. A lot of Linux use is WSL or SSH into servers, where the CLI makes more sense than a GUI.
The GUI earns its memory use for me with LaTeX, inline images and browser views, spreadsheet-region selection, clickable code references, and interactive visualizations. TUIs lose both plain-text simplicity and real GUI capabilities.
