Hi Product Hunt! I built SerialFlow because I was tired of lugging around a laptop just to debug embedded systems, sensors, and IoT devices in the field. I wanted a reliable way to connect an ESP32 or GPS module directly to my phone and actually make sense of the data—without endlessly scrolling through raw logs. SerialFlow started as a simple terminal but quickly evolved into a fully-featured portable workstation. We added fast regex filtering, Modbus RTU views, NMEA parsing, and real-time waveform visualizations so you can diagnose issues instantly, wherever you are. Whether you are debugging firmware, inspecting sensor output, or testing a microcontroller, I hope SerialFlow makes your hardware development process much smoother. I'd love to hear your feedback and answer any questions!
