A Cmd+Tab-style app switcher for macOS that only lists apps with a window on the current Space.
Screen.Recording.2026-08-06.at.9.37.51.PM.mov
Built to stay responsive over high-latency screen sharing.
- macOS 13 or later
- Xcode Command Line Tools (
xcode-select --install) — full Xcode not required
git clone https://github.com/emp/SpaceTab.git
cd SpaceTab
./install.shinstall.sh builds a release binary, assembles SpaceTab.app, installs it to
/Applications, and launches it.
To build without installing, run ./build.sh and open build/SpaceTab.app.
The app lives in the menu bar and has no Dock icon. Quit it from there.
The menu bar icon shows a warning triangle while the hotkey is not live, and the
menu reads Active once it is.
Note: A few screen sharing apps are excluded from it - you can modify the list via the menu bar. So you can still CMD+Tab inside a remote mac, for example.
System Settings → General → Login Items → + → SpaceTab.
