A minimal, dependency-free Python tool to monitor multiple log files simultaneously in a single terminal window. Like tail -f, but for up to 9 files at once in a clean tiled layout. ~315 lines of code. Tested on Ubuntu and macOS. Brought to you & tested via Claude Code Opus 4.5.

Features

• Zero dependencies — Python 3.10+ standard library only
• Quick path — tailgrid /path/ auto-selects .txt/.log/.out/.err files
• Up to 9 tiles — auto-layout or manual grid selection
• Scroll mode — freeze tile with f, scroll with j/k
• Session restore — saves last 10 sessions

Viewer: +/- lines | f freeze | j/k scroll | Tab focus | q quit

Quick start

From PyPI:

pip install tailgrid
tailgrid

Quick start with path (auto-selects .txt/.log/.out/.err files, newest first):

tailgrid /var/log/       # selects all files up to 9 (newest)
tailgrid /var/log/ 4     # 4 newest files shown in 2x2 grid

From source:

git clone https://github.com/ferreirafabio/tailgrid.git
cd tailgrid
python -m tailgrid
