I’ve been dealing with huge log files lately, several GBs in size, and got frustrated with common tools such as Notepad++ freezing and crashing a server with limited RAM. I wanted something fast, relatively lightweight, and install-free for Windows. I have been searched around the web for a while but couldn't find an equivalent, so I built Giant Log Viewer.

Features:

- It is an equivalent of the Linux' `less` pager tool for Windows, but works on Linux and macOS too

- Opens multi-GB UTF-8 unstructured log/text files instantly (without loading everything into memory)

- Navigates through the file using keyboard shortcuts -- jump to the end of the file, go to previous line, etc.

- Limited text/regular expression searching

- Portable -- just unzip and run

- Open-source -- welcome to contribute or fork

Would love your feedback, and if it’s useful, feel free to star it, suggest improvements or even contribute! Depends on the needs of myself and other users, more features might be added.
