FAQ

What is dmux?

A terminal multiplexer that runs multiple AI coding agents in parallel, each in its own tmux pane with a separate git worktree and branch. dmux is a CLI that manages several AI coding agents at once. Each task gets its own tmux pane backed by a separate git worktree and branch, so agents working on different features cannot step on each other's files. When a task finishes, you can merge its branch back into the main branch or push it and open a GitHub pull request from the pane menu.

dmux is open source under the MIT license. Check the license terms before using it in commercial products.
