Portie
Port intelligence for macOS. See every open port, which app owns it, and shut it down from one window.
No more guessing which process is holding port 3000. Portie shows every open TCP and UDP port on your Mac, identifies the app that owns it, and lets you kill it without touching the terminal.
Features
Live local monitoring: Every open port on your Mac, refreshed automatically every 3 seconds using native APIs. No shell commands, no sudo required for most ports.
View by app or port: Switch between a flat sortable table and a view grouped by application. Filter and search by port number, app name, or address.
Process control: Gracefully quit or force-kill any process directly from the port list. SIGTERM first, SIGKILL fallback after 3 seconds. Keyboard shortcut included.
Remote port scanner: Scan any hostname or IP address for open ports with automatic service identification. Customize port ranges, timeout, and concurrency. Scans the top 100 common ports by default.
