tmux is described as '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' and is a very popular terminal emulator in the os & utilities category. There are more than 10 alternatives to tmux for Linux, Mac, Windows, Rust and Wayland. The best tmux alternative is GNU Screen, which is both free and Open Source. Other great apps like tmux are WezTerm, byobu, Zellij and RMUX.
Offers full-screen terminal multiplexing with independent windows, VT100 emulation, scrollback, and copy-paste. Supports ANSI standards, detaching, and persistent background process execution for shells or commands across Unix-like systems.
A GPU-accelerated cross-platform terminal emulator and multiplexer written by @wez and implemented in Rust
Byobu is a GPLv3 open source text-based window manager and terminal multiplexer. It was originally designed to provide elegant enhancements to the otherwise functional, plain, practical GNU Screen , for the Ubuntu server distribution.
Zellij is a terminal workspace. It has the base functionality of a terminal multiplexer (similar to tmux or screen) but includes many built-in features that would allow users to extend it and create their own personalized environment.
Universal Rust multiplexer for the agentic era: detachable, scriptable, and inspectable, with a tmux-compatible CLI, daemon-backed SDK, and native Ratatui integration.
Automatically tiles and organizes all terminal sessions in one native macOS window, scaling layouts from fullscreen to grid, grouping sessions by project with color-coding, enabling instant filtering, supporting any CLI tool, and requiring zero configuration.
dtach is a tiny program that emulates the detach feature of screen, allowing you to run a program in an environment that is protected from the controlling terminal and attach to it later. dtach does not keep track of the contents of the screen, and thus works best with programs...
abduco provides session management i.e. it allows programs to be run independently from their controlling terminal. That is programs can be detached - run in the background - and then later reattached. Together with dvtm it provides a simpler and cleaner alternative to tmux or...

It has the most intuitive key bindings and the vastest range of capabilities amongst the ones I have tried. However, the first thing you should do after installation is to change command character because it is terrible choice.
