Byobu review
A free, mature terminal multiplexer with persistent sessions, layouts, and configurable status indicators.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Byobu is a free, GPLv3 open-source terminal multiplexer and text-based window manager for Linux, BSD, and macOS. It wraps tmux or GNU Screen and is intended for terminal users, developers, system administrators, and people managing persistent shell sessions over local terminals or SSH. Its interface adds function-key shortcuts, window and pane controls, profiles, configurable color themes, and a two-line system-status bar with configurable indicators. The overall fit is strongest for users already familiar with tmux or Screen who want a more guided layer around those backends.
Session and layout management are Byobu’s clearest strengths. Users can create, rename, reorder, and split windows and panes, then detach and reattach persistent sessions. Split-pane layouts can be saved and restored, while the interactive configuration menu provides a way to adjust settings without relying only on command-line options. These features suit ongoing shell work where terminal state needs to remain available across disconnects or later sessions. Persistence is local: sessions remain on the machine where Byobu and its tmux or GNU Screen backend run, so it is oriented toward local terminals and SSH workflows rather than a hosted session service.
Byobu keeps its commercial model simple: it is free open-source software, with no paid tiers described. Installation options include common Linux package managers, Homebrew on macOS, or installation from source. Its platform and ecosystem fit comes from supporting tmux and GNU Screen rather than replacing them with a separate multiplexer backend. That makes it a practical choice for mature terminal users who want function-key controls, profiles, status indicators, and layout handling in one interface. Users seeking a graphical terminal manager or persistence beyond the local host should choose an alternative aligned with those needs.
