LogExpert is a good answer to a narrow question: how do I follow and search a log file on a Windows PC without freezing the editor? But it is Windows-only, it needs the .NET desktop runtime, and some people simply want a tool that also runs on a Linux jump host or a Mac. This article compares LogExpert with the alternatives admins actually ask about: klogg, BareTail, Notepad++, PowerShell and a log server. Facts come from the projects’ own pages, checked on 6 November 2026. We have not installed or tested any of these tools ourselves.
The short answer
Stay with LogExpert if you work on Windows and want tail mode, highlighting and column views in one free program. Pick klogg if you need Linux or macOS, or if your files are measured in gigabytes. Use Notepad++ or PowerShell when you only need a quick look at a live file. Move to a log server such as Graylog Open when the question is no longer “what is in this file” but “what happened across twelve machines”.
LogExpert and its alternatives side by side
| Criterion | LogExpert | klogg | BareTail | Notepad++ |
|---|---|---|---|---|
| Version we checked | 1.50.0 (marked Latest on its releases page) | 22.06 is the latest stable release; newer builds are only “continuous” pre-releases | Release 3.50a (2006) on the vendor page | 8.9.8.1 |
| Platforms | Windows only | Windows, Linux, macOS | Windows; the vendor lists systems up to Vista | Windows |
| Follow a growing file | Yes (tail mode) | Yes (follow mode and reload on change) | Yes | Yes (Monitoring toggle, file becomes read-only) |
| Regex search and filter | Regex search, filter view, filter to tab | Regex search with AND/OR/NOT, predefined filters | String highlighting | Regex search; no dedicated log filter view |
| Column view for structured logs | Yes (columnizer plugins, log4j XML, Serilog compact JSON) | Not listed in the pages we read | No | No |
| Triggers and plugins | Yes | Not listed | No | General-purpose plugins |
| Licence | Free, open source | GPLv3 or later | Free version with a start-up splash screen; licence terms not readable when we checked | See the project page |
| Install | ZIP, setup, Chocolatey, winget; portable mode | Installer or portable on Windows; DEB, RPM, AppImage, DMG | Single executable | Installer |
LogExpert: what it does well
LogExpert is a Windows tail program and log analyser. Its feature list covers tail mode, tabs, regex search, a filter view that can send results to a new tab, line highlighting, triggers that create a bookmark or run a plugin, and columnizers that split lines into columns. Recent releases added opening a file at a given line from the command line, for example LogExpert.exe "C:logsapp.log" --line 1234. It needs the .NET 10 desktop runtime and, in portable mode, stores settings next to the program. For the full walk-through see our LogExpert page. One note: that page still shows the previous version number, 1.43.0; the vendor’s releases page lists 1.50.0 as the latest.
klogg: the cross-platform choice
klogg started in 2016 as a fork of glogg and describes itself as a fast log explorer. It reads files from disk without loading them into memory, and its README says files of 10 GB and more are not a problem. Search uses Perl-compatible regular expressions, and since release 22.06 it supports combining conditions with AND, OR and NOT. It is licensed GPLv3 or later and runs on Windows, Linux and macOS. The caveat is release cadence: the last stable version we found is 22.06 from June 2022, with development builds published since. That may be fine for a read-only viewer, but you should know it before you standardise on it. We could not reach the original glogg site when we checked, so we say nothing about that project’s current status.
BareTail: the old classic
BareTail is a single small executable with tabs and configurable line highlighting, and it handles files over 2 GB according to the vendor. The vendor page, however, lists Windows versions only up to Vista and shows release 3.50a dated 2006. The free version shows a start-up splash screen. We could not read the licence page, so check the terms yourself before using it in a company. We do not recommend it for new deployments when maintained alternatives exist.
Notepad++ and PowerShell: no extra install
Notepad++ has a Monitoring (tail -f) toggle that watches the open file for changes. The manual notes that it turns the file into a de-facto read-only view. That is enough to watch a small log; it lacks the filter view and columns of a dedicated viewer. If you only need the last lines in a console, PowerShell does it with Get-Content app.log -Tail 50 -Wait. Microsoft documents -Tail as the number of lines from the end of the file and -Wait as checking the file once per second for new lines.
When a viewer is the wrong tool
A file viewer shows one file on one machine. If you search the same patterns on many servers, you want central collection. Graylog Open is free and runs on a Linux server; our page lists version 7.1.9 and a Data Node plus MongoDB as required components. On a small Windows network, EventSentry Light watches event logs on up to five machines. Our guide to free security and audit log tools explains where each fits.
How to choose
- Windows admin, mixed formats, wants highlighting and columns: LogExpert.
- Linux or macOS, or very large files: klogg.
- One-off look at a live file: Notepad++ monitoring or
Get-Content -Wait. - Dozens of sources, alerts, retention: a log server, not a viewer.
FAQ
Is there a LogExpert alternative for Mac or Linux?
LogExpert is Windows-only. klogg runs on Windows, Linux and macOS and is licensed GPLv3 or later.
LogExpert vs Notepad++: which one for logs?
Notepad++ can follow a file with its Monitoring (tail -f) toggle, but it is a general editor. LogExpert adds a filter view, highlighting rules, triggers and column views built for logs.
What is a free alternative to BareTail?
LogExpert and klogg are both free. BareTail’s vendor page still shows a 2006 release and lists Windows only up to Vista.
What happened to glogg?
klogg began in 2016 as a fork of glogg. We could not reach the glogg site when we checked, so we cannot confirm its current status.
How do I tail a file without installing anything?
In PowerShell, run Get-Content file.log -Tail 50 -Wait. It prints the last 50 lines and keeps checking for new ones.
Which runtime does LogExpert need?
The current README lists .NET 10 as the requirement. Older builds ran on the .NET Framework that ships with Windows.
