tmux vs screen vs Zellij
Choosing the right terminal multiplexer for your workflow, with a feature-by-feature comparison.
tmux
The de facto standard
tmux is the most popular terminal multiplexer with a massive ecosystem of plugins, themes, and integrations. It's highly scriptable and powers countless developer workflows.
Best For
Developers, sysadmins, and power users who want maximum control and extensibility.
GNU Screen
The original
Screen is the grandfather of terminal multiplexers, created in 1987. It's still maintained and useful, but lacks modern features like true color and proper split support.
Best For
Legacy systems, simple use cases, or when tmux isn't available.
Zellij
The modern alternative
Zellij is a newer terminal multiplexer written in Rust with a focus on user experience. It features floating panes, WebAssembly plugins, and a beginner-friendly interface.
Best For
Users who want modern UX out of the box without extensive configuration.

How to choose
- You work on remote servers. Pick tmux. It is in every major Linux distribution's package manager, so the same keys and config work on your laptop and on the server.
- You want to script your workspace. Pick tmux. Every action is a command you can run from a shell script, which is how people build whole project layouts with one command.
- You want on-screen hints while you learn. Zellij shows the available keys at the bottom of the screen, which makes the first days easier. You may need to install it yourself on servers.
- You are on an old system or a serial console. GNU screen has been around since the 1980s, is often already installed, and can connect to serial devices directly.
Coming from GNU screen?
The ideas carry over directly: screen's sessions and windows work much like tmux's. The main difference is the prefix key, Ctrl+a in screen and Ctrl+b in tmux. Many people who switch move the tmux prefix to Ctrl+a, as shown in the configuration guide.
| Task | screen | tmux |
|---|---|---|
| Start a named session | screen -S work | tmux new -s work |
| List sessions | screen -ls | tmux ls |
| Reattach | screen -r work | tmux attach -t work |
| Detach | Ctrl+a d | Ctrl+b d |
| New window | Ctrl+a c | Ctrl+b c |
| Next window | Ctrl+a n | Ctrl+b n |
| Scroll back | Ctrl+a [ or Esc | Ctrl+b [ |
Our Recommendation
tmux is the best choice for most users. Its massive ecosystem, excellent documentation, and battle-tested reliability make it the industry standard. The learning curve pays off with unmatched flexibility and power.
For Power Users
tmux + plugins gives you complete control
For Beginners
Zellij's UI hints help, but tmux skills transfer better
For Servers
tmux is one install command away on any server, and widely supported
