LogoRRR

The clue is in your logs. LogoRRR helps you find it with a color-coded heatmap, linked text and timeline views, and reusable literal or regular-expression searches. Keep the investigation in view, then move straight to the lines that matter. Normal log analysis stays on your computer.

Open multiple log files and compressed bundles, follow growing files, and investigate across tabs or detached windows. LogoRRR is a desktop app for macOS, Windows and Linux.

Use the full app for 30 days, then make an optional one-time purchase for permanent access. No credit card is required to start the trial, there is no automatic charge and no subscription. After the trial, opening files and starting new analysis require a purchase; loaded work remains available to read and copy.
