A community fork released opentmux 0.1, describing itself as ‘tmux – the terminal multiplexer before AI was introduced’ and branching from tmux 3.6a to keep an AI-free version of the multiplexer. The Codeberg project appeared on September 11, 2026 and Fedora began packaging opentmux 0.1 for Fedora 43, 44, and 45 on September 14, offering an alternative to tmux’s contribution policy, which allows AI-assisted code that is either too trivial to copyright or produced by providers that publicly disclaim copyright in their output.
