Why HALTWARE?

When your process hangs, your system freezes, or your script goes rogue — reach for the button.

Instant Hardware Kill

Physical button sends kill signal directly to your target process. No software delays.

Beautiful Rust TUI

Ratatui-powered terminal interface with ASCII art logo, color-coded status, and real-time logs.

Process Browser

Press Tab to browse all running processes. Live search, arrow-key navigation, instant attach.

Animated Kill Flash

When you kill a process, get a satisfying full-screen animation with animated skull and pulsing banner.

Nuclear Mode

Press '!' to enable nuclear mode — kills the entire process tree, not just one PID.

USB Plug & Play

ESP32-based hardware. Works on Linux, macOS, and Windows. Driver-free on Linux/macOS. Windows requires CP2102 driver.

Things This Won't Fix

Let's be honest about what you're getting.

Will Fix

Runaway processes
Infinite loops
Frozen Docker containers
npm nightmares
AI agents gone rogue

Won't Fix

Your code quality
Imposter syndrome
Vim (you're stuck forever)
Your dating life
That merge conflict

Totally Unnecessary Features We Added Anyway

Because overkill is the best kind of kill.

3-Frame Animated Skull

Why 3 frames? Perfect balance. 2 frames: too jerky. 4 frames: too smooth. 3 frames: just right.

Color-Coded Process Status

Green, red, yellow — like a tiny traffic light for death. Because visual feedback matters.

Event Log with Timestamps

For process forensics. When you need to know exactly when that rogue process died.

60fps TUI Rendering

Because watching processes die should be smooth. Lag is for losers.
