## What it is
Toolong is a terminal application (TUI) for viewing, tailing, merging, and searching log files, including JSONL. It handles multi-gigabyte files quickly, auto-detects timestamps to merge logs, and syntax highlights common web server log formats.

## Use cases
- tail log files in the terminal
- view huge multi-gigabyte log files instantly
- merge multiple log files by timestamp
- pretty print and search JSONL files
- open compressed .bz and .bz2 log files
- analyze web server logs with syntax highlighting

## When to choose
- you need a fast, interactive TUI for inspecting logs on a server over ssh
- you work with JSONL or compressed log files regularly
- you want to merge logs from multiple sources by timestamp

## When to avoid
- you need centralized log aggregation or alerting across a fleet (use ELK, Loki, etc.)
- you prefer plain unix tools like tail, less, and grep in scripts
- you need a GUI-based log viewer
