FastLog is now available on itch.io. It’s a lightweight, Windows-native command-line tool designed to analyze large log files quickly without opening them in slow or crashing text editors. FastLog works directly from the terminal and processes logs incrementally, making it suitable for files ranging from small debug logs to very large ones.
The free version is fully usable and intended for everyday debugging and quick inspection. It shows the top 50 results, runs in a single thread, and requires no installation or external dependencies. You can download it instantly and start using it right away.

For users who regularly work with large logs, a Pro version is also available. The Pro version removes limits, enables multi-threaded processing for better performance, and supports exporting results to JSON for further analysis or automation.
FastLog was built to save time when working with logs, and feedback from real users is highly appreciated. If you deal with large log files and prefer working from the command line, feel free to try it out and share your thoughts.
