Install
- macOS
- Windows
- Linux
Download the installer from claude.com/product/claude-science and double-click to install. On first launch, the app sets up its runtime and starter Python and R environments, which takes a few minutes, then opens a new tab in your default browser. If no browser tab appears, click Claude Science in the Dock.
Claude Science is a local application, not a website, so there’s no public URL to visit. On Windows it opens in its own window, and on macOS and Linux it opens in a browser tab. Open it from the application itself: Claude Science in Applications or the Dock on macOS, the Start menu on Windows, or the
claude-science command on Linux. On a remote server, the sign-in link reaches your browser through an SSH tunnel; see Run on a remote Linux server.Sign in and complete setup
When the app opens, sign in with your Claude account. On Windows, click the Sign in on the web button and confirm with Continue; the app opens claude.ai in your default browser and continues in the app window once you approve the sign-in there. No API key is required. If you approve the sign-in in your browser but Claude Science doesn’t continue (for example, on a remote server when the sign-in can’t return through the SSH tunnel), sign in with a code instead:- Go back to the Claude Science sign-in screen and select Paste code instead, then Open on web.
- Approve access in the browser, then copy the whole code the page shows.
- Paste the code into Claude Science. If the sign-in doesn’t continue on its own, select Continue.
Claude Science keeps your data in a single folder in your home directory:
~/.claude-science on macOS and Linux, and %USERPROFILE%\.claude-science on Windows. On Linux, the claude-science command itself installs to ~/.local/bin, and on Windows the app installs to %LOCALAPPDATA%\Programs\ClaudeScience and adds that folder to your user PATH. Beyond that, it doesn’t modify your existing conda installation, R libraries, or shell configuration. To remove Claude Science, see Uninstall Claude Science.Run your first analysis
- Open the Example project, or create a new one.
- Start a conversation. Reference a folder on your computer by typing its path or using the @ picker in the composer.
- Review the folder-access card when it appears and choose whether to allow it.
- Review the code-execution card when Claude proposes running code and choose whether to allow it.
- Results appear as artifacts in the Files panel.

Remove the Terminal command
The app also adds a
claude-science command for Terminal. Remove it with rm ~/.local/bin/claude-science.~/.claude-science folder.Troubleshooting first launch
- macOS says the application isn’t supported, or the app icon appears crossed out: the download page picked the build for the wrong processor. Return to the download page and choose Mac (Intel) or Mac (Apple Silicon) to match your Mac. To check which you have, open the Apple menu, choose About This Mac, and look at the Chip or Processor line.
- No browser tab appeared on macOS or Linux: on macOS, click Claude Science in the Dock. On Linux, copy the printed URL into a browser on the same machine, or run
claude-science urlto print a fresh one. - On macOS, some of Claude’s tools can’t start and the error mentions the Xcode license, usually right after an Xcode update: macOS won’t run the Python that comes with Apple’s developer tools until the license is accepted. Open Xcode and agree to the license with an administrator account, or run
sudo xcodebuild -license acceptin Terminal, then ask Claude to try again. - A Claude Science message on Windows says the app was not installed because the file could not be confirmed: the copy you opened still runs but isn’t installed. Download the installer again from claude.com/product/claude-science and open the new file. If the message persists, the PC could not verify the publisher’s signature, so ask your IT team.
- The Windows app reports that it couldn’t set up the app window engine: the first launch downloads that engine from
downloads.claude.ai, and this usually means the app couldn’t reach it. Check the internet connection, and on a corporate network ask IT to allow that domain (see Network requirements). - On Linux, the installer stops with
The download service may be unreachable, or not yet available in your region: the installer couldn’t get the latest version fromstorage.googleapis.com. Check the internet connection, and on a corporate network ask IT to allow that domain (see Network requirements). Claude Science is available where Anthropic offers claude.ai. See Supported countries and regions. - On Linux, the shell reports
command not foundforclaude-science:~/.local/binisn’t on your PATH. Add the PATH line that the installer printed to your shell profile, then open a new terminal. - On Linux,
claude-science servestops withSandbox unavailable: bwrap not found on PATH: bubblewrap isn’t installed, or isn’t on your PATH. Install bubblewrap and socat with the command for your distribution in the Linux tab of Install. - On Linux,
claude-science servestops withSandbox unavailable: bwrap too old: the installed bubblewrap is older than 0.8.0. Check the version withbwrap --version, then upgrade bubblewrap. Ubuntu 24.04’s repositories carry a new enough version and Ubuntu 22.04’s don’t. - On Linux,
claude-science servestops withSandbox unavailable: bwrap cannot create unprivileged user namespaces: the kernel or an AppArmor profile blocks the sandbox from creating user namespaces. The rest of the message names the settings to check on Ubuntu, Debian, and other distributions, and changing them takes administrator (sudo) access. - On Linux, an error says
socat is required for Linux sandbox networking but was not found in PATH: socat isn’t installed, or isn’t on your PATH. Install socat with the command for your distribution in the Linux tab of Install. - Projects from another computer don’t appear: by design, Claude Science keeps your work on the computer where it’s installed, so each computer starts with its own projects. Your earlier projects are still on the other computer. See Use Claude Science on more than one computer.
- Projects you created under another sign-in on this computer don’t appear automatically, for example, after you move from a personal plan to your organization’s Team plan: your earlier projects are still in that sign-in’s folder. Select the Review button on the banner at the top of the home screen, or select Review next to Access previously saved Claude Science work on this computer under Settings > General > Account, to access them. On Team and Enterprise plans, if there’s no banner and the setting is grayed out, your admin controls it. See Access work from another sign-in on your computer.
- Sign-in stops at claude.ai: your account is on the Free plan (upgrade required), the redirect couldn’t return (use Paste code instead), or your Team or Enterprise organization hasn’t enabled Claude Science yet.
- After you paste a code, Claude Science says the code wasn’t recognized or was issued for an earlier sign-in attempt: select Open on web again, approve access, and paste the whole new code. If it says
PKCE state missing or expiredinstead, select Back and follow the steps in Sign in and complete setup again.
