  • A modern, browser-based serial terminal for UART communication with microcontrollers, embedded devices, and IoT hardware. No installation required - just open in your browser and connect to your serial device. UART machine using the native Web Serial API. HEX/ASCII views with synchronized scrolling. JSON command scripting for automated hardware testing. Packet timing controls that actually understand how real serial traffic behaves. Export logs with timestamps. Switch themes without burning your retinas. For hardware hackers who want their tools compact, powerful, and just a little bit pretty.
