Origin story
Existing serial monitor tools—including the Arduino Serial Monitor—often prioritize basic functionality over developer experience. ComChan was built to provide a faster, more capable, and more ergonomic serial debugging workflow.

A fast minimal serial monitor with serial plotter TUI for embedded systems
A Blazingly Fast Minimal Serial Monitor with serial plottter TUI and more
From the maintainer
First workflow
I suggest the users to install ratty (By Orhun Parmakisiz) and try out the 3D telemetry either via the simulate mode or using actual hardware which outputs Pitch, Yaw, Roll
Design choice
The main thing that makes it different is that it is mainly terminal-based (TUI) unlike other programs which are mostly GUI.
Roadmap
I want to add a feature allowing comchan users to view CAN/MODBUS logs and plot it. Which makes it easier to debug stuff.
