Claude Desktop: What It Does That the Website Doesn't
September 7, 2026
Claude Desktop is the native Claude app for Mac, Windows, and — in beta — Linux. It's free to install, and the short answer to "is it worth it over the website" is: the Chat tab is a nicer window onto the same thing, and the other two tabs are the actual reason to install it.
The app has three tabs:
| Tab | What it's for | Needs a paid plan |
|---|---|---|
| Chat | Normal Claude conversations | No |
| Cowork | Longer agentic work and Dispatch | Yes |
| Code | Software development with Claude Code | Yes |
If you only ever use Chat, the desktop app buys you a dedicated window, a global hotkey, and voice mode without a browser tab. If you write code or run long tasks, it buys you something the website structurally cannot do: access to your local files, your terminal, and your git repositories.
Platforms, honestly
| Platform | Status | How you get it |
|---|---|---|
| macOS | Stable | Universal build — one download covers Intel and Apple silicon |
| Windows x64 | Stable | Installer |
| Windows ARM64 | Stable | Separate ARM64 installer |
| Linux | Beta | apt or .deb, Ubuntu 22.04+ / Debian 12+ only |
Linux is genuinely supported now, which surprises people who last checked a year ago — but it's beta, it's Debian-based distributions only, and a few features aren't there yet. We covered the details, and what to run on Fedora or Arch instead, in Claude on Linux.
On Windows, the Code tab needs Git for Windows installed before it will work, and you have to restart the app after installing it. Nothing warns you about this in advance.
Signing in, and the API key trap
Claude Desktop signs in with a claude.ai subscription or your organisation's SSO.
It does not accept a Claude Console API key. This catches developers out regularly: you have an API key, you have billing set up in the Console, and the desktop app still won't let you in. That's expected. Console API keys and claude.ai subscriptions are separate products with separate billing — an API key authenticates the Claude Code CLI and the SDKs, not the desktop app.
So if your budget lives in API credits rather than a subscription, use the CLI.
What the Code tab actually gives you
This is the part worth installing for, and it's more than a chat box next to your editor:
- Parallel sessions with git isolation — several tasks running at once without stepping on each other's working tree
- Visual diff review before changes land
- An integrated terminal and file editor
- Live app preview, so Claude can look at what it just built
- Pull request monitoring
- Side chats for a quick question that shouldn't derail the main session
- Computer use — letting Claude control apps and the screen, where supported
- Dispatch sessions from your phone, picked up later on the desktop
Same engine as the CLI. Different ergonomics: the CLI is one focused conversation in a terminal, the desktop app is a workspace holding several at once. Plenty of people run both and switch depending on the task.
Is Claude Desktop free?
The app is free to download and install, and the Free plan covers Chat on desktop alongside web, iOS, and Android.
What the free plan does not include is Claude Code, which means the Code tab — and Cowork — need a paid plan. Anthropic lists what each tier includes on its pricing page, and that page is the only reliable source, since plan contents change.
The honest framing: install it free, use Chat, and upgrade only if the Code or Cowork tabs are what you came for.
Desktop, web, or CLI?
| You want to... | Use |
|---|---|
| Chat, with a dedicated window and a hotkey | Desktop, Chat tab |
| Chat from any machine, nothing installed | claude.ai in a browser |
| Work on code with local files and git | Desktop, Code tab |
| Script it, pipe it, run it in CI | Claude Code CLI |
| Work inside your editor | The VS Code extension |
The web app is not a lesser version of the desktop app for chatting — it's the same conversations, synced. It simply can't touch your filesystem, which is the entire point of the other two tabs.

FAQ
Is there a Claude desktop app for Mac?
Yes. The macOS build is a universal binary, so one download runs on both Intel and Apple silicon Macs.
Is Claude Desktop free?
The app is free to install, and the free plan includes Chat on desktop. The Code and Cowork tabs require a paid plan.
Is there a Claude app for Windows?
Yes, with separate installers for x64 and ARM64. The Code tab additionally requires Git for Windows, and you need to restart the app after installing it.
Can I use my API key with Claude Desktop?
No. Claude Desktop authenticates with a claude.ai subscription or organisation SSO. For API key authentication, use the Claude Code CLI or the SDKs. Console API billing is separate from a claude.ai subscription.
What's the difference between Claude Desktop and Claude Code?
Claude Code is the coding agent; Claude Desktop is one of the places it runs. The desktop app's Code tab and the terminal CLI use the same engine, with the desktop adding parallel sessions, visual diffs, an integrated editor, and app previews.
Does Claude Desktop work offline?
No. It's a client for a hosted model and needs an internet connection.
The short version
Install it free, use Chat, and treat the Code tab as the real feature. Mac and Windows are stable, Linux is a Debian-only beta, and the one gotcha that costs people an hour is that a Console API key will not sign you in.
The reason a desktop app beats a browser tab here is access — to your files, your terminal, your machine. Taku starts from the same premise and asks what else local access buys you: not one assistant with a filesystem, but a workspace where AI apps and agents other people built arrive runnable, and you keep the ones that earn their place. The marketplace is the short version. Taku is in Beta, and the Mac app is available now.
