Good to know
Pattern matching
This tool checks known error patterns; it does not use AI and cannot diagnose every crash. A clean result means no supported pattern matched.
Performance warnings
“Can’t keep up!” shows that ticks are late, not why. CPU load, world generation, plugins, storage and memory can all contribute.
Questions
Do my logs leave my computer?
