Best Terminal Multiplexers
Compare tmux, Zellij, WezTerm and cy: sessions, panes, tabs, detach and reattach, plus configuration and platform differences.
Updated
short verdict
Pick tmux if you need detach and reattach over SSH on BSD, Linux, macOS or Solaris. Pick Zellij for floating panes, layouts and WASM plugins with working defaults. Pick WezTerm if you want multiplexing inside the terminal emulator, configured in Lua. Pick cy if session replay and Janet scripting matter more than ecosystem size.
A terminal multiplexer runs several shells in panes, windows or tabs inside one screen, and often lets you detach a session and reattach later. tmux and Zellij are standalone programs that run inside any terminal. cy follows the tmux model with replay and a Lisp-style config. WezTerm is a terminal emulator with a multiplexer built in, so it replaces both layers.
this page is for
- Developers keeping long-running processes alive over SSH
- Users who want panes and layouts with minimal configuration
- People who want one Lua-configured terminal with tabs, splits and workspaces
- Users who want to replay and search past terminal output
The default multiplexer: detachable sessions, panes and windows, written in C for BSD, Linux, macOS and Solaris.
best for
- Persistent sessions over SSH
- Servers and minimal environments
- Scripted session setup
strengths
- Detach a session and reattach from the same or a different terminal
- Session sharing between multiple users
- Scriptable through configuration files
- Runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS and Solaris
weaknesses
- Needs libevent 2.x and ncurses when building from source
- Source install is ./configure && make, with no plugin system described by the project
- All control goes through keyboard shortcuts and commands, with no floating panes
A Rust multiplexer with tiled, stacked and floating panes, layouts, and WebAssembly plugins, usable on default settings.
best for
- Newcomers to multiplexers
- Reproducible workspaces via layouts
- Browser access to a session
strengths
- Floating and stacked panes alongside tiled panes
- Plugins in any language that compiles to WASM
- Built-in web client to reach sessions from a browser
- Try it without installing via bash <(curl -L https://zellij.dev/launch)
weaknesses
- Platform support is not listed by the project
- Installing from Cargo means a Rust toolchain: cargo install --locked zellij
- Multiplayer mode and web client add surface area a solo user may not need
A GPU-accelerated terminal emulator with native tabs, panes and workspaces, configured entirely in Lua on Linux, macOS and Windows.
best for
- Windows users who want multiplexing
- Lua-scripted terminal setups
- One tool for emulator and multiplexer
strengths
- Multiplexer works over SSH
- Runs on Linux, macOS and Windows with the same config
- Lua is a full programming language for configuration
- Ligatures and image support in the emulator
weaknesses
- You must use WezTerm as your terminal; it is not a program you run inside another emulator
- Session persistence and detach behavior is less documented than in tmux
A tmux-style multiplexer with time-travel replay of session history, fuzzy finding and Janet configuration.
best for
- Reviewing and searching past terminal output
- Users who want a programmable Lisp-style config
- Searchable command history across sessions
strengths
- Replay and search any terminal session history
- Ctrl+R interface to revisit and insert earlier commands
- Built-in fuzzy finding and thumbs text selection
- Configured in Janet rather than a fixed config format
weaknesses
- Much smaller adoption than tmux, Zellij or WezTerm
- Janet is a language you probably have to learn before customizing
- Language, license and platform support are not listed
How to choose
The deciding factor is usually where you work and how much configuration you want to write.
- Remote servers and SSH persistence: tmux, with detach and reattach on BSD, Linux, macOS and Solaris.
- Working defaults without a config file: Zellij, which ships layouts and floating panes out of the box.
- Windows support: WezTerm, which runs on Linux, macOS and Windows.
- Extending with plugins: Zellij for WASM plugins in any compiling language, WezTerm for Lua scripting.
- Searching and replaying past output: cy, with time-travel replay and a Ctrl+R command history.
When not to use these
- You only need one shell per window and already use a terminal emulator with tabs.
- You need a multiplexer on a host where you cannot install software or build from source.
FAQ
- What is the best terminal multiplexer for SSH sessions?
- tmux is the usual pick. You can detach a session, let it keep running in the background, and reattach from the same or a different terminal. WezTerm's multiplexer also works over SSH.
- Is Zellij a replacement for tmux?
- For most multiplexing tasks, yes. Zellij has tiled, stacked and floating panes, layouts, multiplayer sessions, WASM plugins and a web client. tmux covers more platforms explicitly, including the BSDs and Solaris.
- Does a multiplexer replace a terminal emulator?
- tmux, Zellij and cy run inside a terminal emulator. WezTerm is an emulator with a built-in multiplexer, so it covers both roles.
- Which multiplexer is configured with a programming language?
- WezTerm uses Lua and cy uses Janet, a Lisp-like language. tmux uses configuration files, and Zellij supports layouts and personal configuration.
