Dtask

A modern, open-source cross-platform desktop app built with Electron v41.3.0 + React v19.2 + Vite that lists all network processes with their ports and lets you kill them with one click.

Features

• Process table — lists all network processes with PID, name, listening port(s), protocol, and optional command-line path
• Search — filter by PID, process name, or port number
• Sortable columns — click any column header (PID, Name, Ports, Protocol) to sort ascending/descending
• Kill processes — single-click kill with confirmation modal; system process protection (PID < 1000)
• Batch kill — checkbox-select multiple processes and kill them all at once
• Kill by port — Ctrl+K opens a dialog; enter a port to find and kill the owning process
• Port conflict detector — ports shared by multiple processes are highlighted with an amber indicator
• Group by executable — collapse same-name processes (e.g. chrome.exe × 12) into one expandable row
• Command-line column — toggle to show full executable paths and arguments, with hover tooltip
• Export CSV — download dtask-processes-*.csv with all filtered rows
• Suspend / Resume — pause a process (yellow indicator) and resume it later
• Change highlighting — new processes since the last refresh pulse green for 2.5 seconds
• Auto-refresh — toggle to refresh every 3 seconds
• System tray — minimize to tray on Windows/Linux; right-click → Kill by port
• Window state persistence — remembers size and position across restarts
• Dark-mode-first — modern UI with shadcn/ui components and Tailwind CSS v4
• Responsive header — full toolbar on wide windows, hamburger command menu on narrow

Install

npm install

Development

npm run dev

Build

Build the app for packaging:

npm run build

Create distributables:

# All platforms
npm run dist

# Platform-specific
npm run dist:win    # Windows NSIS installer
npm run dist:mac    # macOS DMG
npm run dist:linux  # Linux AppImage

GitHub Release

Tag and push to trigger CI:

npm version patch   # or minor / major
git push origin v0.1.1

Keyboard Shortcuts

Shortcut	Action
Ctrl+S	Focus search input
Ctrl+K	Open Kill by Port dialog
Ctrl+R	Refresh process list
Escape	Clear search / close dialogs

Platform Support

Platform	Process Detection	Process Killing	Suspend/Resume
Windows	netstat -ano + tasklist	taskkill /F /T /PID + taskkill /F /IM	PowerShell NtSuspendProcess/NtResumeProcess
macOS	lsof -iTCP -sTCP:LISTEN	kill -9	kill -SIGSTOP / kill -SIGCONT
Linux	ss -tunlp (fallback netstat)	kill -9	kill -SIGSTOP / kill -SIGCONT

Security

• contextIsolation: true — renderer is isolated from Node.js
• nodeIntegration: false — no direct Node API access in renderer
• All OS commands run exclusively in the main process
• Preload script exposes a minimal, typed API surface
• PID validation and system process guards prevent accidental damage
