## What it is
Sloth is a native macOS application that displays all open files, directories, sockets, pipes, and devices in use by running processes, serving as a graphical front-end to the lsof command-line tool. It offers filtering, sorting, and detailed inspection of file and socket usage across the system.

## Use cases
- find out which app is using a file on mac
- see what processes have a file open
- gui for lsof on macos
- check which process is using a port or socket
- investigate open files held by an app
- find processes locking a file

## When to choose
- you need a visual, searchable view of open files and sockets on macOS
- you want lsof functionality without memorizing command-line flags
- you need to debug which apps are holding files, pipes, or network sockets

## When to avoid
- you are on Linux or Windows rather than macOS
- you need scriptable, headless output - use lsof directly
- you need deep kernel-level tracing beyond what lsof provides
