Free plan · Open source See pricing ↓

RMUX is a tmux-compatible terminal multiplexer and Rust terminal automation engine that keeps shell sessions alive, scriptable, and inspectable. It exposes a tmux-compatible 90-command CLI surface plus typed SDKs for Rust, Python, and TypeScript to programmatically create sessions, send keys, wait for output, and take structured snapshots. It also includes a 'Web Share' feature to expose an encrypted, browser-accessible terminal session. It runs natively on Windows, macOS, and Linux.
