OpenAI ChatGPT Desktop App for Linux: Supported Distros, Bundled Apps, and Release Timing

On August 11, 2026, OpenAI expanded ChatGPT to Linux, its fourth desktop OS, releasing a native desktop app in public preview alongside existing macOS and Windows clients . This closes what the company called "the last gap in its desktop lineup" — Linux was one of the most-requested platforms for the desktop app, and the launch extends ChatGPT and Codex across every major desktop operating system .

Supported Linux Distributions

The preview is officially tested and validated on these specific versions :

• Ubuntu 24.04 LTS and 26.04 LTS
• Debian 13
• Fedora 43 and 44
• Architectures: x64 (amd64) and ARM64
• Package formats: .deb (with an OpenAI apt repository) and .rpm

Because these distributions are the base for many downstream Linux variants (such as Kubuntu, Linux Mint, and other Debian or Red Hat-family derivatives), OpenAI expects a wider set of desktops to run the app — but the company does not test or guarantee compatibility on those systems .

"In practice, this means you can run on most Debian and Red Hat-family Linux distributions," ZDNET noted after testing the app on Linux Mint . Community packages for Arch Linux have already appeared in the AUR, though Arch is not officially supported .

Apps Bundled in the Single Desktop Application

The desktop app bundles three work surfaces in one native window :

• ChatGPT — the standard conversational AI interface for everyday questions and research
• ChatGPT Work — a built-in productivity workspace with a browser for research and document editing, designed for longer professional tasks
• Codex — OpenAI's coding agent for writing, debugging, and explaining code, with access to local projects, files, repositories, terminals, and developer tools

The app also supports importing projects, chats, skills, and plugins from other AI tools, and features automatic updates to keep work synced across devices . Browser actions work in the built-in browser or Chrome, but controlling other desktop apps is not yet supported in this preview .

Timeline Comparison with Anthropic's Claude Desktop App for Linux

Anthropic's Claude desktop app for Linux launched approximately six weeks before OpenAI's, on June 30, 2026, in beta . Here's how the two releases compare:

Detail	OpenAI ChatGPT	Anthropic Claude
Linux release date	August 11, 2026 (public preview)	June 30, 2026 (official beta)
Release status	Public preview	Beta
Supported distributions	Ubuntu 24.04/26.04 LTS, Debian 13, Fedora 43/44	Ubuntu 22.04+, Debian 12+ (Ubuntu/Debian only; no Fedora support)
Architectures	x64 and ARM64	x86_64 and arm64
Apps/modalities bundled	ChatGPT + ChatGPT Work + Codex	Claude Chat + Claude Code + Claude Cowork
Install mechanism	.deb (apt repo) and .rpm packages	.deb via Anthropic's apt repository
Notable limitations	No native Computer Use; dictation not available	No Computer Use or dictation in this beta

OpenAI's preview arrived later but covers a wider distro range — including Fedora 43 and 44 (which Anthropic does not officially support) — and ships as both .deb and .rpm packages . Anthropic's initial Linux support is narrower, limited to Ubuntu 22.04+ and Debian 12+, with no Fedora or RHEL package yet .

Both apps are still in pre-GA stages (preview vs. beta), and neither has reached stable general availability on Linux.

Key Takeaways

• OpenAI released the ChatGPT desktop app for Linux on August 11, 2026, as a public preview — the first official native Linux client .
• Officially supported distros are limited to five specific versions: Ubuntu 24.04 LTS, Ubuntu 26.04 LTS, Debian 13, Fedora 43, and Fedora 44 .
• The app bundles ChatGPT, ChatGPT Work, and Codex in one native window, available for x64 and ARM64 as .deb and .rpm packages .
• Anthropic's Claude desktop app for Linux launched about six weeks earlier (June 30, 2026) but with narrower distro support (Ubuntu and Debian only) .
