Tmux is a terminal multiplexer that allows users to create and manage multiple terminal sessions within a single window. It offers features like session persistence, window and pane splitting, and customization options, enhancing productivity for Linux users, especially those working with remote servers or VMs.
Zellij is a terminal workspace similar to tmux or screen, offering base functionality with additional features for personalization. Users can split the terminal into panes and tabs, and define a map of panes in a configuration file for easy setup. Zellij includes a layout engine and supports plugins written in any compiled language, such as the Strider file explorer. It uses Webassembly and WASI for plugin execution.
