Zellij Terminal Multiplexer

Zellij is a modern terminal multiplexer written in Rust, designed as a user-friendly alternative to tmux and screen with built-in layouts, floating panes, and plugin system. Created by Aram Drevekenin and the Zellij organization in 2020, with over 22,000 stars as of 2026. Key features include: workspace and tabs (multiple tabs with keyboard-driven creation, switching, and renaming, each containing independent pane layouts), pane management (horizontal and vertical splits, floating panes that overlay tab content, and tab/pane renaming), built-in layouts (predefined and custom layout files in KDL format for reproducible workspace setup with named panes and commands), plugin system (WebAssembly-based plugins compiled to WASM running in a sandboxed environment, enabling status bars, session managers, and custom UI extensions), KDL configuration (human-readable configuration format for keybindings, themes, layouts, and plugin definitions), themes (built-in and custom color themes with syntax highlighting in the tab bar and status line), session management (detach from sessions, list and attach to existing sessions, and automated session resurrection), mode system (normal, locked, pane, tab, resize, move, search, session, and tmux modes for contextual keybindings), search (full-text search within terminal scrollback buffer with highlighted matches and navigation), floating panes (panes that float above the tiled layout for temporary command output or monitoring), strider (built-in file browser for quick file navigation and opening), and cross-platform (Linux, macOS, and with WSL on Windows).
