OpenAI has released the ChatGPT desktop app for Linux, closing the last big gap in its desktop line-up. The release went out worldwide on Tuesday, 11 August 2026, and it is a preview build rather than a finished product. It bundles three things in one window: regular ChatGPT, ChatGPT Work, and Codex, OpenAI’s coding agent.
Until now Linux users had the browser and, for Codex, a command-line tool or an editor extension. This is the first time the graphical Codex workflow runs natively on the platform.
Which distros the ChatGPT desktop app for Linux supports
OpenAI has tested the app on a short list of distributions. That list is narrower than it looks in practice, because each of these is the base for a large family of downstream desktop spins.
- Ubuntu: 24.04 LTS and 26.04 LTS, desktop variants
- Debian: 13
- Fedora: 43 and 44
- Architectures: x64 and ARM64, both supported
- Packages: DEB and RPM builds for each architecture
- Licence: closed source, despite the Linux release
Downloads are on OpenAI’s own site. Only DEB and RPM packages are listed for the preview, so distributions outside the tested list are largely on their own. Arch Linux is not officially supported, though community packages are already on the AUR — useful, but community-maintained and not backed by OpenAI.
What OpenAI said
The company framed the launch as a response to demand rather than a new product direction.
“Linux has been one of the most-requested platforms for the desktop app, and this launch extends ChatGPT and Codex across every major desktop operating system,” the company said Tuesday.
What it actually does on your machine
The draw over the browser version is local access. Codex can open projects on your disk, edit files, work with Git repositories and run commands with your user’s permissions. The app can also read local files without uploading them somewhere first, and hook into other applications through extensions. You switch between the ChatGPT and Codex modes from a menu in the top-left corner.
That capability list is also the reason to slow down before installing it. This is a closed-source binary asking for access to your filesystem and the ability to execute commands as you — on a platform whose users generally expect to be able to read what they are running. A preview build with that much reach deserves a scratch VM or a container first, not your main working machine, and it is worth deciding deliberately which directories you point it at. OpenAI’s own framing is honest enough that this is preview software; treat it that way.
Should you install it?
If you already pay for ChatGPT and write code on Linux, the Codex integration is the genuine reason to try it. If you only chat, the browser does the same job without putting a vendor-controlled package on your system. Linux desktop use has been climbing steadily — we looked at the numbers behind that in our piece on Linux crossing 10% desktop share in North America — and this launch is a reasonable marker of the platform mattering enough for commercial vendors to ship for it. It is not a reason to skip the usual caution.
