Plux review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Plux is an open-source terminal multiplexer implemented in Rust for Unix-like systems. It keeps shell processes and terminal state in a background daemon while an attached client handles input and ANSI rendering. Command-line users and developers working on Linux or macOS can create named sessions, detach and reattach to them, split panes, adjust layouts, and preserve terminal state locally. Temporary command sessions are also available through plux run.

Its main strength is focused terminal persistence rather than a broad platform ecosystem. Plux supports vertical and horizontal pane splitting, pane focus and zoom, split-ratio adjustment, scrollback history, history search, mouse selection, and clipboard integration. SSH remote attach adds reconnect support, while clipboard connections include wl-copy, xclip, xsel, and pbcopy. The published feature set also includes custom layouts, but persistence remains local and session synchronization is not supported. This makes Plux suited to users who want a compact Unix workflow centered on durable terminal sessions and pane management.

Plux is distributed as MIT-licensed open-source software, with no paid tier structure described. Its scope is deliberately narrow: Windows is unsupported, and the category specifications list no collaboration or plugin and extension system. Those constraints matter for teams that need shared sessions, synchronized state, or an extensible multiplexer environment. Users who primarily need local persistence, SSH reconnect, and core pane and history controls should find the feature set well aligned; users requiring cross-platform access, collaboration, synchronized sessions, or plugins should choose a product built around those capabilities instead.
