Introducción

Zellij is a terminal workspace (multiplexer) written in Rust. Unlike tmux with its steep learning curve and cryptic keybindings, Zellij ships with discoverable UI hints, sane defaults, and a layout system. First released in 2021 by Aram Drevekenin, it quickly became the go-to tmux alternative for developers who want modern UX.

What Zellij Does

  • Panes — horizontal, vertical, floating
  • Tabs — named, reorderable
  • Sessions — persist across detach/reattach
  • Layouts — KDL-based declarative layouts
  • Floating panes — overlay panes
  • Plugin system — WebAssembly plugins (WASI)
  • Session manager — built-in session picker
  • Discoverable UI — mode indicators and key hints at bottom
  • Copy mode — search and select text
  • Themes — built-in themes

Architecture

Rust binary using crossterm for terminal rendering. Plugins run as WASM modules (WASI), isolated and sandboxed. Each pane is a separate PTY process. State is serialized for session persistence.

FAQ

Q: Zellij vs tmux? A: Zellij works out of the box (beginner-friendly, discoverable UI, floating panes); tmux is more mature (stable server, larger community, deeper customization). Both work, but Zellij is 10x easier to pick up.

Q: Can it be used with Alacritty? A: A perfect match. Alacritty (minimal terminal) + Zellij (pane management) is a golden combo for many developers.

Q: Does it support SSH? A: Run Zellij inside an SSH session. After disconnecting, zellij attach restores it.
