SerialFlow
Turn your Android into a portable serial debugging station.
SerialFlow is a modern USB serial terminal that turns your Android device into a portable debugging workstation. Built for developers working with Arduino, ESP32, STM32, and IoT hardware. Monitor data, send commands, and find key info using fast regex filtering and protocol decoding (Modbus, NMEA). Pro features unlock real-time waveform visualization, 3D attitude tracking, and GPS diagnostics.
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!
