spacecake

spacecake is an open-source desktop app for Claude Code.
It combines an integrated terminal, visual markdown editor, and live task tracking.
You can run agents, write specs, and see what's happening in one place.

ℹ️ spacecake is in public alpha.

🚀 getting started

Download an installer for your platform from the latest release:

• macOS: Download the .dmg file (arm64 for Apple Silicon, x64 for Intel)
• Windows: Download the .exe installer
• Linux: Download the .deb file (for Debian-based distributions like Ubuntu) or .AppImage for other distros
• macOS (ZIP): Download the .zip file for manual installation

linux & windows users: for best file watching performance, install watchman. spacecake will show a tip in the status bar recommending this.

On first launch, spacecake opens the home folder (~/.spacecake) for general notes.
Press ⌘O (macOS) or ctrl+O (Windows/Linux) to open your project as a workspace.

🖥️ integrated terminal

Claude Code integration

spacecake provides deep integration with Claude Code:

• context awareness: tells Claude which file and line you're editing
• plan mode: enabled by default when running in the spacecake terminal
• status line: auto-configured on first launch, shows live metrics (model, context %, cost)
• plans panel: press ctrl+G to view and manage plans
• open files: Claude can open files directly in the editor and wait for you to save and close before continuing

See the Claude Code integration docs for more details.

🔀 git

built-in git integration with a dockable panel:

• changes: view modified, staged, and untracked files with inline diffs
• commit: select files, write a message, and commit (with amend support)
• branches: create, switch, and delete branches from a popover
• sync: fetch, pull, and push with ahead/behind indicators
• stash: quick stash, pop, and drop
• history: browse recent commits and view per-commit diffs
• merge conflicts: dedicated conflict editor for resolving conflicts
• clone / init: clone a repo (⌘⇧C) or initialise a new one from the menu bar
• GitHub: links to view on GitHub and create pull requests

📋 tasks

the tasks panel shows live Claude Code tasks from the active session, with status filters and sortable columns.
dock it left, right, or bottom alongside the terminal and git panels.
