ZForceClose

No-mercy window killer for Windows 10/11 and Linux (X11).

When an app refuses to die, press your hotkey to arm ZForceClose, move your cursor over the frozen window, and press again. The process is terminated instantly — TerminateProcess on Windows, SIGKILL on Linux. No dialogs. No grace period. No mercy.

How it works

1. Launch ZForceClose — it lives in your system tray.
2. Press your global hotkey (default Ctrl+Shift+K) to arm kill mode.
3. Move your cursor over the frozen window.
4. Press the hotkey again — the process is terminated instantly.
5. Click the overlay widget or wait 8 seconds to cancel.

Features

• Configurable global hotkey (arm + confirm, two-press flow)
• System tray with quick-kill action
• Process blacklist (protects explorer.exe, systemd, your DE compositor, etc.)
• Kill history log with timestamps and results
• Start at login (Windows registry / Linux XDG autostart)
• Experimental: sound + screen flash on kill

Build from source

Requires Rust, Node 18+, and the Tauri prerequisites for your platform.

pnpm install
pnpm tauri dev      # development
pnpm tauri build    # release bundle

Platform notes

• Wayland is not supported in v1. ZForceClose needs to resolve the window under the cursor — Wayland blocks cross-app window inspection by design. Switch to an X11 session on Linux.
• On Linux, you may need libx11-dev / libxcb*-dev packages.
• Killing elevated (admin) processes on Windows requires running ZForceClose as Administrator.
