history

Project history and usage

3mux is a Go terminal multiplexer positioned as an i3-inspired, lower-friction alternative to traditional multiplexers such as tmux.

Project history

The official repository was created in 2019 and the README describes 3mux as a terminal multiplexer with search, mouse-controlled scrollback, session management, and i3-like keybindings. Its early GitHub releases moved from v0.1.0 in April 2020 to v1.0.0 in May 2020 and v1.1.0 in March 2021.

Adoption history

The package-manager footprint is small but real: the input facts list Homebrew, MacPorts, and Nix packages, while the README also documents installation from Go source.

How it is used

3mux is used from the terminal to split panes, move between panes with i3- or vim-like keybindings, search scrollback, resize panes, and manage sessions without a large tmux configuration.

Why package nerds care

Its package-nerd appeal is as a compact terminal-multiplexer alternative: a single Go CLI that packages familiar tiling-window-manager ideas for shell sessions.

Timeline

2019: GitHub repository created.
2020: v0.1.0 release published.
2020: v1.0.0 release published.
2021: v1.1.0 release published.

Related projects

The README explicitly frames 3mux against tmux and borrows interaction ideas from i3.
