Why I Built This
As someone who frequently works with multiple devices connected to my PC, I often found myself navigating through Windows Device Manager just to check COM port assignments. This repetitive task highlighted the need for a simpler solution.
While some serial monitor applications include port listing features, I wanted a lightweight, standalone tool that does one thing and does it well - showing available COM ports instantly. SerialSpotter was born from this need, designed to be minimal, fast, and always ready when you need it.
