Scrutiny Debugger

An open source debugging, development and testing tool for C/C++ embedded applications that works through instrumentation.

Compares to NXP FreeMaster, STM32CubeMonitor, MCUViewer, Micrium uC/Probe, Segger J-Scope or XCP based software -- but free, vendor-agnostic, with a Python SDK, multi-client support and does not need a debug probe.
