## What it is
zmx is a lightweight terminal session persistence tool written in Zig that lets users attach and detach from shell sessions without killing them. It is a minimal tmux alternative focused solely on session persistence, deliberately omitting windows, tabs, and splits.

## Use cases
- persist terminal sessions across ssh disconnects
- detach from a long-running shell and reattach later
- share a terminal session between multiple clients
- send commands to a running session without attaching
- print scrollback history of a terminal session as plain text
- replace tmux when you only need session persistence

## When to choose
- you want tmux-like session persistence without panes, tabs, or splits
- you prefer native terminal scrollback over multiplexer-provided scrollback
- you need to script commands into a persistent session without attaching
- you run macOS or Linux and want a small, fast single-purpose tool

## When to avoid
- you need window/tab/split management that tmux or zellij provide
- you are on Windows
- you need a full terminal multiplexer with layouts and status bars
