The Absolute LogViewer

The Absolute LogViewer is a fast, lightweight log file viewer built natively for Windows with WPF and .NET 10. Designed specifically for reading, tailing, and analyzing log files — not bloated with editor features you don't need.

Split-pane view: compare two log files side-by-side with synchronized scrolling. Each pane has its own independent tail status and search context.
