rmux

rmux is a terminal multiplexer and automation engine that keeps shell sessions alive and scriptable.

RMUX is a tmux-compatible multiplexer and terminal automation engine designed for agents and programmatic control. It keeps terminal sessions alive, scriptable, and inspectable, allowing code to act as the user in a manner similar to Playwright. Users can share a terminal in the browser using encrypted web-share sessions. The platform provides official SDKs including Rust with rmux-sdk, Python with librmux, and TypeScript with @rmux/sdk. It supports the same commands and behavior as tmux while enabling terminal automation workflows. It is natively available on Windows, macOS, and Linux.
