WMUX review
A focused open-source choice for keeping local terminal work organized and alive.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WMUX is an open-source terminal multiplexer for keeping shells, servers, logs, builds, agents, and project workspaces running after a terminal client disconnects. Its persistent server owns terminal state while clients remain disposable, with sessions, windows, and panes providing the core structure. The project targets Windows, Linux, and macOS, including Intel and Apple Silicon macOS builds, making it suited to desktop users who want a consistent multiplexing model across those operating systems.
The feature set covers the main mechanics expected from a focused terminal multiplexer. Users can split, navigate, resize, and zoom panes; name and target sessions, windows, and panes; and configure key bindings and command parsing. Copy mode, paste buffers, mouse support, configurable themes, and animations add control over terminal interaction and presentation. Custom layouts are supported, while local installers are available through shell or PowerShell. Together, these features make WMUX a practical fit for managing several related terminal tasks in one workspace without depending on a persistent client connection.
WMUX is free and open source, so its pricing model is straightforward: there is no paid tier to evaluate. The main boundary is scope. Persistence is local rather than cross-device, and the product is centered on individual terminal workspaces rather than shared collaboration or plugin-based expansion. Choose WMUX if you want persistent sessions, pane organization, and native desktop support across Windows, Linux, and macOS. Consider another tool if your workflow depends on synchronized sessions between devices, collaborative access, or an extensible plugin ecosystem.
