Portsly

A lightweight macOS menu bar app that shows which applications are listening on which ports, with a quick way to kill them.

Features

• View all listening TCP ports and their processes at a glance
• View PIDs, commands and working directories
• Quick "Open in Browser" for web services
• Kill processes with one click (with confirmation)
• Smart name detection for NodeJS apps, Docker, Python and other dev tools
• Filters for dev processes and system process
• Toggleable filters out system processes by default
• Process window with uptime, start time, memory, and details for every listening process

Process Window

Open it from "Open Process Window..." in the menu, or double-click the menu bar icon. It lists one row per process, sortable by any column, so you can see how long each server has been running and kill it from there. The inspector shows the parent process, CPU time, thread count, working directory, full command, and whether each port is bound to localhost only or to all interfaces.

Usage

1. Click the Portsly icon in your menu bar
2. View all processes listening on TCP ports
3. Click on any port to see options:

• Open in Browser: Opens http://localhost:PORT in your default browser
• Kill Process: Sends SIGTERM to the process
• Force Quit: Sends SIGKILL to the process

4. Double-click the menu bar icon (or choose "Open Process Window...") for the full process window
