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 well-known app in the OS & Utilities category. There are eight alternatives to tmux for Linux, Mac, BSD and Xfce. The best alternative is Terminator, which is both free and Open Source. Other great apps like tmux are GNU Screen (Free, Open Source), byobu (Free, Open Source), dtach (Free, Open Source) and mtm (Free, Open Source).
Terminator enables the user to run and manage multiple terminal emulators side-by-side in the same window. The main focus is arranging terminals in a grid. (Tabs is the most common default method, which Terminator also supports.
Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.

Almost everyone thinks GNU Screen is a great alternative to tmux.

byobu vs tmux opinions
Some users think byobu is a great alternative to tmux, some don't.
byobu uses tmux as a back-end. It's literally just alternative keybindings and a predefined status bar. It's tmux configuration, not tmux replacement.
mtm is the Micro Terminal Multiplexer, a terminal multiplexer. It has four major features/princples: Simplicity There are three commands (change focus, split, close). There are no modes, no dozens of commands, no crazy feature list.
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.
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.
