Zellij — Terminal Workspace with Batteries Included

What it is

Zellij is a terminal multiplexer written in Rust that provides sane defaults, discoverable keybindings, a layout system, floating panes, session management, and a WebAssembly plugin system. Unlike tmux, Zellij shows available keybindings at the bottom of the screen, making it immediately usable without memorizing shortcuts.

Developers, DevOps engineers, and terminal power users who want a modern multiplexer that works out of the box without a .tmux.conf file use Zellij. The WebAssembly plugin system enables community extensions without recompiling.

How it saves time or tokens

Zellij eliminates the steep learning curve of tmux. New users are productive in minutes thanks to visible keybinding hints. The layout system lets you define terminal arrangements in KDL files and load them with one command, replacing manual pane splitting. Session persistence means you never lose your terminal layout on disconnection.

How to use

1. Install Zellij:

brew install zellij                         # macOS
cargo install --locked zellij               # Rust

1. Launch a session:

zellij

1. Use the keybinding hints at the bottom. Press Ctrl+p for pane mode, Ctrl+t for tab mode, Ctrl+n for resize mode.

Example

// layout.kdl - Define a development workspace
layout {
    pane split_direction="vertical" {
        pane command="nvim" {
            args "."
        }
        pane split_direction="horizontal" {
            pane command="cargo" {
                args "watch" "-x" "test"
            }
            pane  // empty shell
        }
    }
}

# Load the layout
zellij --layout layout.kdl

Common pitfalls

• Zellij keybindings conflict with some terminal emulators or applications that also use Ctrl+p or Ctrl+t. Use zellij setup --check to detect conflicts and remap keys.
• Nested multiplexers (running Zellij inside tmux or vice versa) cause keybinding confusion. Pick one multiplexer per session.
• WebAssembly plugins are still a young ecosystem. The plugin API changes between versions, so pin your Zellij version when using third-party plugins.
