Ports are virtual points where network connections start and end. They are unsigned 16-bit integers, meaning they can range from 0 to 65,535 , and they help your computer differentiate between multiple services like a web server, a database, or a chat application.

With all these potential issues—orphaned ports, conflicting services, and system-level bugs—it's clear that manually managing localhost ports can be a significant source of friction. This is where the "new" approach, embodied by a tool like , comes in.
