Spacepal for Claude Code

When you run Claude Code in five or ten projects at once, each on its own desktop, the hard part is knowing which one stopped to ask you something. Spacepal marks the desktop whose Claude is waiting for you or has finished, tells you why, and takes you straight to that terminal.

Two sessions waiting, one finished, with each project's branch and dev server. Recorded in Spacepal's demo mode with sample Spaces.

See which session needs you

Spacepal listens to Claude Code's hooks. When a session asks for permission, waits for input or finishes its turn, Spacepal works out which desktop it belongs to from the session's folder, then:

The mark clears when you visit that desktop or answer Claude.

Go straight to the terminal

⌃⌥J goes to the session that has waited longest, then to the ones that finished. Spacepal switches to its desktop and brings that session's terminal tab to the front, in iTerm or Terminal, so you can answer right away. Clicking a marked tile in the overview does the same.

Branch and dev server on every project tile

For desktops whose terminal runs in a project folder, the overview tile shows the git branch, how many files changed, and local servers started from that folder, such as localhost:3000. Click the server to open it in a new browser window on that desktop.

Links open on the right desktop

When Claude Code opens a link, the browser normally adds a tab to the window you used last, which may be on another desktop. Spacepal brings that browser window to the desktop you are on. With the Spacepal MCP server, Claude can also open a page on the project's own desktop with open_url, and see the other sessions with agent_sessions, for example to check whether the backend session has finished.

A desktop for a new project

New Project Space (Windows and Spaces menu) makes a desktop named after a folder and starts Claude Code there. macOS allows 16 desktops per display; when there is no room, Spacepal uses an empty unnamed one. This one is new, so tell us if it does not work for you.

Set it up

  1. Download Spacepal (macOS 14 or later, 14-day free trial).
  2. Open Settings > General > Claude Code and click Add to Claude Code. It adds three hooks (Notification, Stop, UserPromptSubmit) to ~/.claude/settings.json, keeps your other settings and saves a copy of the old file.
  3. Start new Claude Code sessions. Hooks load when a session starts.

Spacepal finds a session's desktop from the terminals it has saved for each desktop, or from a desktop note that names the folder. Everything stays on your Mac: the hooks pass the folder, Claude's message and the terminal's name to Spacepal and nothing else.
