Klogg is a multi-platform GUI application that helps browse and search through long and complex log files. It is designed with programmers and system administrators in mind and can be seen as a graphical, interactive combination of grep, less, and tail.
Please refer to the documentation page for how to use Klogg.

Klogg started as a fork of glogg - the fast, smart log explorer in 2016.
Since then it has evolved from fixing small annoying bugs to rewriting core components to make it faster and smarter that predecessor.
Development of klogg is driven by features my colleagues and I need to stay productive as well as feature requests from users on Github and in glogg mailing list.
Latest news about klogg development can be found at https://klogg.filimonov.dev.
- Runs on Unix-like systems, Windows and Mac thanks to Qt5
- Is fast and reads the file directly from disk, without loading it into memory
- Can operate on huge text files (10+ Gb is not a problem)
- Search results are displayed separately from original file
- Supports Perl-compatible regular expressions
- Colorizes the log and search results
- Displays a context view of where in the log the lines of interest are
- Watches for file changes on disk and reloads it (kind of like tail)
- Is open source, released under the GPL
- Multithreading support for file indexing and regular expression matching
- Log encoding detection using uchardet library (support utf8, utf16, cp1251 and more)
- Limiting search to a part of open file
- In-memory cache of search results per search pattern
- Support for many common text encodings
- And lots of small features that make life easier (closing tabs, copying file paths, favorite files menu, etc.)
