LogExpert is a free, open-source Windows log viewer and analyzer that provides a graphical alternative to the Unix tail command. It monitors log files in real time and automatically displays newly appended entries. Users can open multiple files in a tabbed interface and search their contents using text or regular expressions. Custom highlighting rules make important events, warnings, and errors easier to identify. Its filtering system can isolate matching entries in separate tabs for focused investigation. Bookmarks and configurable triggers help users navigate logs and respond to specific events. A plugin architecture supports structured columns, additional log sources, Unicode text, and formats such as log4j XML and compact Serilog.
