yesterday we shipped Codex for Linux 🐧

the full Codex desktop experience is now on Ubuntu, Debian and Fedora

parallel agents, worktrees, diffs, skills, automations and browser workflows, all right where you already build

so so happy this one is out! https://t.co/J4qYUlNt6K

Codex for Linux is finally here

TL;DR: The ChatGPT desktop app for Linux is now available in preview. Read the official Linux installation guide to choose the right .deb or .rpm package.

If you’ve been waiting for the Codex desktop experience on Linux, this one’s for you. It’s finally here.

The ChatGPT desktop app is now available on Linux in preview, bringing Codex, ChatGPT, and Work together in one app. Open your repositories, run multiple coding agents in parallel, review their changes, and keep your projects moving right where you already build.

The Codex CLI already supports Linux. Now the desktop experience is here too, with parallel coding tasks, project management, and code review.

What you get

Open the app, sign in with your ChatGPT account, and select Codex. From there, you can work directly with local repositories, files, terminals, and developer tools.

You can:

• Run several coding tasks in parallel and keep each task’s context separate.

• Use Git worktrees so agents can work in the same repository without overwriting each other’s changes.

• Review diffs, inspect what changed, and continue the work in your editor.

• Ask Codex to build features, fix bugs, refactor code, run tests, and investigate unfamiliar codebases.

• Use skills to give Codex your team’s instructions, preferred workflows, and project-specific context.

• Schedule recurring work and return when the results are ready.

• Use the built-in browser or Chrome extension for browser-based tasks.

You can also switch to ChatGPT for quick questions or Work for longer tasks such as research, documents, and analysis.

Supported Linux distributions

The preview supports:

• Ubuntu 24.04 LTS and 26.04 LTS

• Debian 13

• Fedora 43 and 44

Both x64 and ARM64 processors are supported. Ubuntu and Debian use .deb packages; Fedora uses .rpm packages.

To check your architecture:

bashuname -m

x86_64 means you need the x64 package. aarch64 or arm64 means you need the ARM64 package.

Download and install

Choose the package for your distribution and processor:

• Ubuntu or Debian · x64: Download ChatGPT for Linux (.deb, x64)

• Ubuntu or Debian · ARM64: Download ChatGPT for Linux (.deb, ARM64)

• Fedora · x64: Download ChatGPT for Linux (.rpm, x64)

• Fedora · ARM64: Download ChatGPT for Linux (.rpm, ARM64)

Ubuntu and Debian

Download the .deb package, open a terminal, and run:

bashcd ~/Downloads sudo apt install ./chatgpt_amd64.deb

On ARM64, replace chatgpt_amd64.deb with chatgpt_arm64.deb.

Fedora

Download the .rpm package and run:

bashcd ~/Downloads sudo dnf install ./chatgpt.x86_64.rpm

On ARM64, replace chatgpt.x86_64.rpm with chatgpt.aarch64.rpm.

After installation, launch ChatGPT from your applications menu or run chatgpt in your terminal. Sign in, select Codex, and open a project or local folder.

Updates through your package manager

The installer configures a signed OpenAI package repository, so future updates work through the package manager you already use.

On Ubuntu or Debian:

bashsudo apt update sudo apt install –only-upgrade chatgpt

On Fedora:

bashsudo dnf upgrade –refresh chatgpt

Wayland support

Native Wayland support is experimental and will continue to improve. In a Wayland session, the app uses XWayland when available. To explicitly select native Wayland, fully quit the app and launch it from a terminal:

bashchatgpt –ozone-platform=wayland

Some features, such as floating windows, window positioning, focus, and keyboard shortcuts, may not fully work while native Wayland support matures.

Built for real development workflows

The useful part of the desktop experience is being able to delegate several pieces of work without losing track of any of them.

You might ask one agent to investigate a failing test, another to implement a feature, and a third to review an existing change. Each task stays organized, and worktrees keep concurrent changes isolated. You can inspect the results, ask for revisions, or open the code in your editor when you want to take over.

The built-in browser and Chrome extension also work on Linux. That means browser-based tasks remain available alongside local coding workflows, whether you’re checking documentation, testing a web app, or gathering information needed for a change.

Skills let you make those workflows more specific. Add your repository’s conventions, testing instructions, or deployment checklist, and Codex can apply them as it works.

Linux-native sandboxing

Codex’s open-source Linux sandbox uses bubblewrap by default to restrict the files and processes available to an agent. Under workspace-restricted settings, it keeps the broader filesystem read-only and permits writes only in approved workspace roots.

The sandbox also protects sensitive paths such as .git and .codex, isolates processes with Linux namespaces, and applies seccomp restrictions. Codex uses your system’s bwrap when available and can fall back to its bundled copy.

You still control which folders Codex can access and when a task needs additional permissions. If you want the implementation details, the Codex Linux sandbox source is public.

More Linux capabilities are on the way

Codex, ChatGPT, Voice, the built-in browser, and the Chrome extension are already available on Linux. We’re actively working to bring native Computer Use to Linux soon, so Codex and ChatGPT can interact with desktop applications such as GIMP and OpenOffice too.

That work will also make room for features that depend on native desktop interaction, including Appshots, Record & Replay, and voice requests involving other desktop applications. Browser-based workflows already work today, including voice requests in the browser.

The preview currently focuses on the supported Ubuntu, Debian, and Fedora desktop distributions listed above. Other distributions may work but aren’t formally supported.

Try it

If you’ve been waiting for Codex on Linux, download the package for your system, install it with apt or dnf, and open your first project.
