glogg – Qt graphical log explorer

glogg is a multi-platform GUI application to browse and search through long or advanced log files.

It’s designed with programmers and system administrators in mind. glogg can be seen as a graphical, interactive combination of grep and less.

glogg can be started from the command line, optionally passing the file to open as an argument, or via the desktop environment’s menu or file association.

Features include:

  • Fast and reads the file directly from disk, without loading it into memory.
  • Provides a second window showing the result of the current search.
  • Reads UTF-8 and ASCII / ISO-8859-1 files.
  • Supports grep/egrep like regular expressions. There’s support for wildcards and fixed strings.
  • QuickFind search types with incremental QuickFind.
  • Colorizes the log and search results.
  • Displays a context view of where in the log the lines of interest are.
  • Configurable font family and size.
  • Option to load your last session.
  • Optional line numbers main and filtered views.
  • Follow file mode – refreshes a growing log file.
  • Cross-platform support – runs under Linux, macOS, and Windows systems.
