#log-analysis Startups & Tools

LogoRRR is a desktop log viewer and visual log analyzer for macOS, Windows and Linux. Its linked heatmap, text and timeline views help developers and support engineers find patterns, narrow an incident and inspect the original log lines. Literal and regular-expression searches can be reused and assigned colors. Open multiple logs and supported compressed bundles, follow growing files and work across tabs or detached windows. Normal log analysis stays on the device; log contents are not uploaded for analysis. License activation, verification and user-initiated restore can use the network. The full app has a 30-day trial without a credit card or automatic charge. After the trial, opening files and starting new analysis require a one-time purchase for permanent access. Loaded work remains available to read and copy. There is no subscription.
