## What it is
tmux is a terminal multiplexer written in C that lets users create, access, and control multiple terminal sessions from a single screen. Sessions can be detached and run in the background, then reattached later.

## Use cases
- keep long-running processes alive after disconnecting from ssh
- split one terminal window into multiple panes
- share a terminal session between users for pair programming
- detach and reattach terminal sessions across reboots of my laptop
- manage many shell sessions from a single screen
- run persistent development environments on a remote server

## When to choose
- you work over SSH and need sessions that survive disconnects
- you want to split and organize terminal windows without a full window manager
- you need a mature, widely supported tool on Unix-like systems

## When to avoid
- you only need a single terminal with no session persistence
- you are on Windows without WSL or a Unix-like environment
- you want a GUI-based terminal manager

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cli, terminal-ui, developer-tools
- domain: developer-tools
- platform: bsd, cross-platform, cli
- tags: terminal-multiplexer, session-management, c, command-line, linux, macos
