Xylem

Every Claude Code session. One window.

A Mac app for Claude Code: one tab per conversation, and you always see which one needs you.

Download for Mac Free. For macOS 26 or later on Apple silicon (M1 or newer).

Xylem runs the same claude you use in Terminal and leaves your Claude Code settings alone. Try it: pick a tab in the window above, or a feature below.

Features

Up and running in a minute.

Xylem uses the Claude Code you already have, with your account, settings and sessions.

  1. Install Claude Code

    Skip this if claude already works in your terminal.

    curl -fsSL https://claude.ai/install.sh | sh

  2. Download Xylem

    Open the downloaded file and drag Xylem into Applications. It's signed and checked by Apple.

    Download for Mac

  3. Open a project folder

    Xylem picks up the last Claude conversation in that folder, or starts a new one. If it can't find claude, the Doctor at the bottom of the window shows how to fix it.

Questions

Does Xylem change my Claude Code settings?

No. Xylem only reads your settings files. To know what each tab is doing, it gives claude a few extra hooks when it starts a tab (through --settings), without changing any of your files.

What leaves my Mac?

Nothing about you or your code. Xylem checks status.claude.com for outages, skills.sh for the skills directory, and every few hours this site for a new version of Xylem. If Xylem crashes, it sends a crash report to Sentry with the error, macOS version, Mac model and Xylem version, never your prompts, files or IP address. Claude Code talks to Anthropic as usual.

Which Macs does it run on?

Macs with Apple silicon (M1 or newer) on macOS 26 Tahoe or later.

Does it work with nvm, mise or a custom config folder?

Yes. Tabs start claude the same way your terminal does, so nvm, mise, Homebrew and your own PATH setup all work. A custom CLAUDE_CONFIG_DIR is picked up too.

Why isn't it in the App Store?

App Store apps run in a sandbox, and a sandboxed app can't open a real terminal session. So Xylem is a direct download, signed and notarized by Apple.

How much does it cost?

Xylem is free to use. Claude Code usage is billed by Anthropic as usual, through your Claude plan or API key.

Is Xylem made by Anthropic?

No. Xylem is an independent app. Claude and Claude Code are Anthropic's products.
