SerialX: A Browser-Based Serial Monitor for Embedded Developers

When developing embedded firmware, one application almost always remains open throughout the development cycle: A Serial Monitor. Whether I'm working with an ESP32, STM32, Arduino, or another microcontroller, UART output is usually the first place I look when debugging firmware, verifying sensor readings, or testing communication protocols. Over time, I noticed that my debugging workflow had become fragmented. I would use one application to view serial logs, another to plot sensor values, anothe
