## What it is
LogExpert is a Windows GUI log file viewer and tail program, acting as a feature-rich replacement for the Unix tail command. It supports highlighting, filtering, bookmarking, columnizing, and third-party plugins for parsing log formats.

## Use cases
- tail log files on Windows with a GUI
- analyze large log files with filtering and highlighting
- split log lines into columns with columnizer plugins
- bookmark and search log entries with regex
- view log4j XML and Serilog compact format logs

## When to choose
- you need a Windows GUI alternative to tail for monitoring logs
- you want filtering, highlighting, and bookmarks while inspecting logs
- you need plugin-based parsing of custom log formats

## When to avoid
- you need a cross-platform or command-line log viewer
- you work primarily on Linux or macOS
- you need centralized log aggregation rather than local file viewing

## Facets

- maturity: active
- function: logging, gui, plugin-system, search-engine
