Claude Cowork on Windows and Linux: How to Run It in 2026

You bought a Max subscription on the strength of a Claude Cowork demo: a desktop agent quietly working through a folder of spreadsheets, drafting a deck, organizing receipts while you did something else. You install Claude Desktop on your Windows laptop, sign in, and start looking for the feature. Or you are on Ubuntu, you go to download the app, and there is no Linux build at all. The question underneath both moments is the same one: where does Cowork actually run, and what do you do if your machine is not on the list.

This guide answers the platform question directly. It covers Claude Cowork on Windows (supported, with a few hardware caveats), the Linux situation (no official app, and what your options are), how the shared-folder workspace behaves once you are in, and where a cross-platform, open-source workspace fits for people whose operating system or use case sits outside what Cowork covers well.

A quick note on what Cowork is, so the platform answer lands in context. Claude Cowork launched in January 2026 as Anthropic’s desktop agent for non-technical knowledge work: research, analysis, organizing local files, producing finished deliverables. It runs on the same underlying engine as Claude Code, tuned for delegation rather than software development. You point it at shared local folders, it can use the browser through Claude in Chrome, run desktop plugins, and execute scheduled tasks. It is a capable product for the audience it targets. Platform reach is simply where the questions cluster, so that is the focus here.

Is Claude Cowork available on Windows

Yes. Claude Cowork came to Windows on February 10, 2026, roughly a month after the macOS research preview, and Anthropic shipped it with feature parity to the Mac version. File access, plugins, MCP connectors, and multi-step task execution all work on Windows the way they do on macOS. If you searched for “claude cowork for windows” expecting a half-finished port, what you get is better than that: it is a full release.

One caveat matters before you assume your specific Windows machine qualifies. Cowork runs its agent inside a sandboxed virtual machine, and on Windows that depends on the Hyper-V virtualization stack. Hyper-V ships with Windows Pro, Enterprise, and Education editions, but not with Windows Home, so a Home edition machine may not be able to run Cowork’s sandbox even with a paid Claude plan. Anthropic ships separate Windows installers and readiness checks for x64 and Arm (arm64) processors, so grab the build that matches your machine and run the readiness check first. Requirements like these can shift, so verify the current list on Anthropic’s site before you commit.

How to download and install Claude Cowork on Windows

Getting set up follows a short path. The steps below reflect the launch flow; confirm details on Anthropic’s site since installers change.

1. Confirm you are on a paid Claude plan. Cowork is available on Pro, Max, Team, and Enterprise. A free account will not show the feature, which also answers the common “is claude cowork free” question: it is not.
2. Download the latest Claude Desktop for Windows from claude.com/download. Cowork lives inside the desktop app, not the web app or mobile, so the desktop installer is the thing you actually want when you go to download Claude Cowork.
3. Run Anthropic’s readiness check for Windows (separate checks exist for x64 and arm64). It verifies that your machine meets the virtualization requirements before you rely on the feature.
4. Sign in and open Cowork from inside the desktop app. Point it at a folder you are comfortable letting an agent read and write, and give it a task.

One operational detail worth knowing: the desktop app needs to stay open while a Cowork task runs. Closing the app terminates active work. Anthropic has noted limited ability to assign tasks from mobile on some plans, but execution happens on the desktop.

The Linux situation: no official app, and what to do about it

Here is the part that sends people searching for “claude cowork linux” and coming up frustrated. Anthropic does not ship Claude Cowork on Linux, and as of mid-2026 it does not ship the Claude Desktop app on Linux at all. macOS and Windows are the only officially supported desktops. There is no apt package, no official AppImage, no Flatpak from Anthropic. If you run Ubuntu, Fedora, Arch, or any other distribution as your daily driver, the official answer today is that Cowork is not built for you. Verify the latest status on Anthropic’s site, because this is exactly the kind of thing that can change with a release.

Linux users have a few practical routes in the meantime, each with trade-offs:

• Run a supported desktop elsewhere and connect over SSH. If your goal is coding work specifically, you can run Claude on a Mac or Windows box and point its Code workflow at a remote Linux host over SSH. This keeps your Linux machine as the execution environment while the agent UI lives on a supported OS. It does not give you Cowork’s office-document delegation on Linux, it gives you remote development.
• Community workarounds. Several open-source projects reverse-engineer or repackage the macOS build to run on Linux x86_64, including Nix-based packages that patch the app for Linux. These are unofficial, can break on any Anthropic update, and put you in the position of trusting a third party’s repackaging of a closed app. Use judgment, especially on a work machine.
• A cross-platform alternative. If what you want is a workspace that runs coding agents natively on Linux without a workaround, an open-source tool built for all three desktops is a steadier foundation than a patched binary. More on that below.

A Chromebook lands in the same bucket as Linux for this purpose. ChromeOS will not run the Claude Desktop installer, so Cowork does not install there directly either, and the same SSH-or-alternative options apply.

How the shared-folder workspace behaves

Once Cowork is running on a supported machine, the working model is folder-centric. You grant it access to local directories, and it reads, edits, and creates files inside that scope: spreadsheets, documents, slides, images, whatever lives there. It can reach out through the browser via Claude in Chrome for research, run plugins that extend what it can do, and run scheduled tasks so a job kicks off without you sitting there. The agent operates inside its sandboxed VM, which is why the virtualization requirement exists on Windows and why a Linux build is non-trivial for Anthropic to ship.

For office knowledge work, that design is genuinely useful. You hand off a folder and a goal, and you get finished deliverables back. The friction shows up at the edges: when your operating system is not supported, when your work is software development rather than document production, or when more than one person needs to be in the same workspace at once. For those edges, a different shape of tool tends to fit better.

For builders, and for platforms Cowork does not cover

If you write software, or you are on Linux, the gap is not really about Cowork being a weak product. It is built for delegation of office work on macOS and Windows, and it does that job. The mismatch is platform and purpose. Several open-source tools have grown up around running coding agents across operating systems, and the broader landscape is worth a look. Two adjacent guides go deeper than this one: a roundup of Claude Cowork alternatives in 2026 and a survey of Codex GUI tools and desktop apps. This article stays on the operating-system question rather than repeating those comparisons.

Nimbalyst is one option in that space, and worth a mention precisely because of the platform angle this post is about. It is an open-source, AI-native visual workspace that runs multiple coding agents side by side: Claude Code, OpenAI Codex (gpt-5.5), OpenCode, and Copilot, with pluggable agent harnesses so you are not locked to one engine. Each session gets its own transcript, its own git worktree, and a spot on a session kanban board. It includes visual editors for markdown, mockups, diagrams, data models, spreadsheets, slides, and code through Monaco, plus planning docs, task trackers, real-time multiplayer collaboration, and a native iOS companion app.

The relevant detail for this guide: the desktop app runs on macOS, Windows, and Linux, with a native iOS app alongside it. So if you are the Ubuntu user from the opening, you have a workspace that installs on your actual operating system. Nimbalyst leverages and extends Claude Code and Codex rather than replacing them, and the desktop and iOS apps are MIT licensed and free for individual use. It is aimed at software work, not the office-document delegation Cowork is tuned for, so the honest framing is that they serve different jobs. If you want a side-by-side, see Nimbalyst vs Claude Cowork.

Platform availability at a glance

The table below compares where Claude Cowork runs against a cross-platform, open-source workspace for coding agents. Treat the Cowork rows as accurate to mid-2026 and verify current specifics on Anthropic’s site.

Capability	Claude Cowork	Cross-platform open-source workspace (Nimbalyst)
macOS	Supported	Supported
Windows	Supported (Hyper-V required; Pro/Enterprise/Education)	Supported
Linux	Not officially supported	Supported
iOS companion	Mobile task assignment limited on some plans	Native iOS app
Primary use	Office knowledge work, document delegation	Software development with coding agents
Agents	Claude (same engine as Claude Code)	Claude Code, Codex, OpenCode, Copilot
License / cost	Paid Claude plan (Pro, Max, Team, Enterprise)	MIT, free for individual use (desktop and iOS)

The pattern is straightforward. On macOS and Windows for office tasks, Cowork is a strong fit and you may not need anything else. On Linux, or for development work, or when you want to run more than one agent, a cross-platform tool fills the gap.

Where this leaves you

If you are on macOS or Windows and your work is research, analysis, and producing documents, Claude Cowork on Windows or Mac is a capable choice, and you can stop reading here. Download Claude Desktop, confirm your hardware passes the readiness check, and put it to work. There is no need to reach for an alternative when the supported product does your job.

If you are on Linux, on a Chromebook, or building software, the picture is different. Cowork’s desktop app does not install on your platform today, and its strength is office delegation rather than coding. For those situations, a cross-platform, open-source workspace that runs Claude Code and Codex on macOS, Windows, Linux, and iOS is a more natural fit. Nimbalyst is one such option, and you can download it free for individual use at nimbalyst.com. If you want the longer comparison first, the Claude Cowork alternatives roundup and the Nimbalyst vs Cowork breakdown both go further than this platform-focused guide.

Whichever way you go, check Anthropic’s site for the current state of Cowork’s platform support before you make a purchase decision. Software ships on its own schedule, and the Linux answer in particular is the kind that could move.
