## 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.
