OpenAI brings the ChatGPT and Codex desktop app to Linux

OpenAI shipped a Linux preview of its ChatGPT desktop app this week, combining ChatGPT, ChatGPT Work, and Codex into one client with native .deb and .rpm packages for Ubuntu 24.04 and 26.04 LTS, Debian 13, and Fedora 43 and 44, covering both x64 and ARM64.

The Mac and Windows builds launched in July alongside ChatGPT Work. An OpenAI spokesperson said Linux was one of the most-requested platforms for the app, closing the gap with the other two major desktop operating systems. Anthropic's Claude desktop app has faced similar growing pains figuring out how a chat interface should represent an agent running for an hour across several subtasks and file edits, a problem neither company has fully solved yet.

Linux developers were not locked out of Codex before this release. The Codex CLI and IDE extension already run on Linux, and Codex cloud lets you delegate coding tasks without installing anything local. The desktop app adds a coordination layer instead: a place to track multiple long-running agent tasks, inspect generated files, review diffs, and move work between local and cloud execution.

One gap at launch: native Computer Use, letting ChatGPT drive other desktop apps like GIMP or OpenOffice, is not available on Linux, according to OpenAI. That also limits Appshots, Record & Replay, and voice requests tied to desktop apps. In-app browser workflows and Chrome extension support work as they do on Mac and Windows.

If you already script Codex into CI or work mostly from a terminal, the CLI remains the more direct tool. The desktop client is built for coordinating several agents or repositories at once, not for replacing it.
