Log files made simple.
Spot problems at a glance.
LogoRRR turns every log entry into a color-coded visual block. A desktop-native app — your log data never leaves your machine, and it works fully offline. Define search groups, save favourites, and find patterns across files, zips, and directories — on macOS, Windows, and Linux.
