Which One Should You Use?
Choose tmux if...
RECOMMENDED FOR MOST USERS
- You want the most powerful, flexible option
- You need plugins (session save/restore, clipboard)
- You want extensive scripting capabilities
- You're setting up a long-term development environment
- Active community and frequent updates matter to you
Choose GNU Screen if...
BEST FOR QUICK SSH SESSIONS
- You SSH into servers that only have Screen installed
- You need a simple, reliable session keeper
- You're working on legacy systems
- You only need basic window management
- Stability over features is your priority
Choose Byobu if...
BEST FOR BEGINNERS
- You find tmux/screen shortcuts hard to remember
- You prefer F-key shortcuts
- You want a preconfigured, ready-to-use experience
- You're new to terminal multiplexing
Choose Zellij if...
BEST MODERN EXPERIENCE
- You want on-screen hints (discoverable UI)
- You like floating panes
- You prefer a modern, Rust-based tool
- You want layout configuration files
- You're starting fresh with no habits from other tools
The Practical Answer
Learn tmux as your primary tool — it's the most powerful and widely used. But also know basic Screen commands, because you'll encounter servers where Screen is the only option available. If you want a modern alternative with a gentler learning curve, try Zellij.
Byobu: The Best of Both Worlds
Byobu wraps either tmux or Screen with user-friendly F-key shortcuts. On modern systems, it uses tmux as its backend by default:
# Install
sudo apt install byobu # Ubuntu/Debian
brew install byobu # macOS
# Choose backend
byobu-select-backend # Select tmux or screen
# Launch
byobu # Start with F-key shortcutsZellij: The Modern Contender
Zellij takes a fundamentally different approach with mode-based keybindings and built-in UI hints:
# Install
cargo install zellij # Rust
brew install zellij # macOS
# Key modes
Ctrl+P # Pane mode (create, move, resize panes)
Ctrl+T # Tab mode (create, rename, switch tabs)
Ctrl+N # Resize mode
Ctrl+S # Scroll mode
Ctrl+O # Session mode (detach, manage)
Ctrl+G # Lock mode (pass all keys through)Download the Complete Cheat Sheet
