CMTrace Open
A modern, cross-platform, Tauri-powered log analyzer that leaves the original CMTrace in the dust.
Why CMTrace Open?
Microsoft's CMTrace.exe is Windows-only, closed-source, hasn't been updated in years, and only reads CCM-format logs. Admins managing Intune, Autopilot, and modern management need something better.
CMTrace Open doesn't just replace CMTrace.exe. It replaces the workflow of opening logs in Notepad, manually searching for error codes, and cross-referencing Microsoft docs.
