## What it is
RMUX is a terminal multiplexer written in Rust that is tmux-compatible and natively supports Linux, macOS, and Windows (ConPTY). It ships typed SDKs for Rust, Python, and TypeScript so agents and scripts can drive persistent terminal sessions programmatically, plus browser-based Web Share for sharing sessions.

## Use cases
- drive a CLI or TUI app from code
- keep terminal sessions alive across script runs
- automate terminal testing with assertions on output
- replace tmux on Windows without WSL
- share a terminal session in the browser
- let an AI agent control a persistent shell

## When to choose
- you need tmux-like multiplexing with native Windows support
- you want Playwright-style programmatic terminal automation instead of TTY scraping
- you're building agents or CI tooling that must drive interactive CLIs from Rust, Python, or TypeScript

## When to avoid
- you only need plain tmux and are happy on Unix
- you need a battle-tested, decades-mature multiplexer (rmux is young, v0.10)
- you require a permissively documented license (license is unverified/nonstandard)
