RMUX is described as 'Universal Rust multiplexer for the agentic era: detachable, scriptable, and inspectable, with a tmux-compatible CLI, daemon-backed SDK, and native Ratatui integration' and is a terminal emulator in the os & utilities category. There are more than 10 alternatives to RMUX for a variety of platforms, including Linux, Mac, Windows, Rust and Homebrew apps. The best RMUX alternative is tmux, which is both free and Open Source. Other great apps like RMUX are Herdr, WezTerm, GNU Screen and Zellij.
tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
Handle multiple coding agents in real terminals with instant status tracking, persistent sessions that survive disconnects, SSH/mobile reattachment, keyboard and mouse controls, plugin support, and lightweight operation as a Rust binary for enhanced workflows.
