Does Captain Kill Switch save my unsaved work?

No. Apps are asked to quit properly first, but anything still open after a couple of seconds is force-closed, including unsaved work. You should save important files before triggering the kill switch.

Is Captain Kill Switch free to use?

Yes, it is genuinely free forever with no account required, no ads, and no hidden upsells.

Will using Captain Kill Switch log me out of my OS?

No. It uses an allowlist model that only targets ordinary user applications while leaving shell processes and system infrastructure untouched.

How do I set up a custom shortcut key?

Open the menu-bar icon, go to Preferences, select Shortcut, and press your desired key combination.

What platforms are supported?

Captain Kill Switch is cross-platform and supports macOS, Windows (10/11), and Linux.

Does Captain Kill Switch collect personal data?

No. It only sends anonymous usage statistics and crash reports tied to a random install ID. It never tracks personal data, filenames, or open application contents.

About Captain Kill Switch

What the tool does and who it's for

Captain Kill Switch is a quiet menu-bar and system-tray app designed to close all open applications in a single click or with a global hotkey. Built with Rust and Tauri, it runs entirely on your local machine to instantly clear your desktop chaos without logging you out or disrupting core operating system processes. The tool attempts to quit well-behaved apps gracefully first to prevent crash-recovery prompts on relaunch, then force-closes any unresponsive programs after a few seconds. It is completely free, lightweight, private, and available cross-platform for macOS, Windows, and Linux.

Key capabilities

Instant One-Click Reset: Close every running application in milliseconds directly from the menu bar or system tray.

Global Hotkey Support: Bind a custom key combination to trigger the panic button from anywhere without navigating to the menu bar.

Graceful App Shutdown: Asks apps to quit cleanly first to avoid crash-recovery prompts on relaunch, force-closing stubborn apps shortly after.

Session-Safe Allowlist: Protects critical system processes, OS shell, and background desktop services so you are never logged out.

Discreet Tray Icon: Lives quietly in your background menu bar with minimal memory footprint and zero background CPU bloat.

Zero Setup Required: Operates out-of-the-box with no mandatory registration, complex configuration, or permissions maze.

Cross-Platform Support: Delivers identical single-button desktop cleanup performance across macOS, Windows, and Linux.

Local Privacy: Runs 100% locally on your machine with no personal data collection or cloud tracking.
