Keyboard-driven port process killer for developers
Find and kill processes blocking your ports in seconds.
Windows
Port conflicts kill momentum.
A stuck port means opening Task Manager, searching for the process, figuring out which one to kill, and hoping you got the right one. That friction adds up when you're juggling multiple dev servers.
PortKiller removes that gap.
Press Alt+P and an overlay appears instantly. Search, select, kill. No mouse needed, no context switching. You stay in flow and get back to coding.
PortKiller is a lightweight, always-ready Windows utility that shows which processes are using your ports and lets you kill them with a keystroke. It runs quietly in your system tray and appears only when you need it.
- Global Hotkey —
Alt+Pto show/hide from anywhere; change it in Settings - Keyboard Navigation — Arrow keys or vim-style
j/k, fuzzy search, or just start typing a port number - Which process is which — Each row shows the command line, so five

kill 3000,kill 3000-4000,admin,refresh, with suggestions as you type - Range Search — Type
3000-4000to filter to a port range - Pinned Ports — Press
pto pin favorites; they stick to the top - Protocol Filter — One-click toggle for All / TCP / UDP
- Public Binding Badge — Spot ports bound to
0.0.0.0instantly - Multi-Select —
Ctrl+Click,Space, or "select all from this PID" for bulk kill - Safe Kills — Every kill takes two presses, the backend re-checks the process before terminating it, and the result tells you whether the port was actually freed

- Never-Kill List — Mark your own processes as protected
- Real-Time Updates — Newly opened ports are highlighted
- Process Details — Double-click for memory, CPU, command line, quick actions
