openmux review
A free, open-source multiplexer for persistent, tiled terminal workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
openmux is an open-source terminal multiplexer for developers who want persistent local sessions, multiple workspaces, and tiled pane layouts. It runs as a command-line application on macOS and Linux, including supported Apple Silicon, x64, and arm64 environments. Its core workflow combines pane splitting, movement, zooming, closing, and detach-and-attach session management with Vim-style navigation and configurable keybindings.
Its standout feature is the master-stack layout model, which gives users a structured way to arrange panes while keeping nine workspaces with isolated layouts. The aggregate view helps browse and filter pseudo-terminals, while mouse tracking, scrollback, and Kitty graphics protocol support extend the terminal interface beyond basic text navigation. Hot-reloaded configuration lets users change settings without restarting the application, and the headless-style CLI supports session and pane operations. These capabilities make openmux a strong fit for developers who organize work across several local terminal contexts.
openmux is free and open source, with installation methods through npm, Bun, source builds, and prebuilt binaries for supported platforms. Its persistence scope is local, so it suits users who want terminal continuity on a machine rather than hosted synchronization or shared cloud workspaces. The macOS and Linux focus also narrows its fit for teams or individuals working across other operating systems. Choose openmux for tiling-focused local development and configurable terminal control; choose another multiplexer if cross-platform coverage, hosted session access, or collaborative workspaces are central requirements.
