DevKill is a Windows utility that discovers processes listening on ports via native Windows APIs and lets you kill them. It auto-discovers zombie dev servers (Node, .NET, Python, PHP, Vite, and others), shows them in a modern dark Fluent UI, and lets you kill them individually or in bulk. Includes CLI mode (devkill 3000), system tray integration, and auto-refresh.

DevKill

A Windows utility that finds and kills orphaned dev server processes hogging your ports.

Developers accumulate zombie dev servers — Node, .NET, Python, PHP, Vite, and others — that occupy ports and cause conflicts. DevKill auto-discovers these processes, shows them in a modern dark UI, and lets you kill them individually or in bulk.

Features

Auto-discovers listening ports via native Windows APIs (no netstat parsing)
Smart grouping — known dev server processes (Node, dotnet, Python, PHP, etc.) are surfaced in a "Dev Servers" group
Bulk kill — select multiple processes and kill them all at once
System tray — minimizes to tray with quick-kill context menu
CLI mode — run devkill 3000 to instantly free a port without opening the GUI
Auto-refresh — polls every 3 seconds for changes
Search/filter — filter by port number, process name, or PID
Start with Windows — optional auto-start via registry
