Ccmux – Reduce context switching for parallel Claude Code sessions
I’ve been running parallel Claude Code instances while working on different tasks. Two problems kept slowing me down: 1. I was constantly jumping between terminals to see which session needed input. 2. Using git worktrees added setup friction (installing deps, bootstrapping environments, etc.), which discouraged parallel work. So I built ccmux. It’s a thin layer on top of tmux that: - Adds a glanceable sidebar UI showing all Claude Code sessions - Surfaces attention-needed states with visible alerts - Wraps git worktrees with a lightweight workflow abstraction so spinning up parallel tasks…
In plain words
Ccmux is a terminal interface layer for tmux that helps developers manage multiple parallel Claude Code sessions. It displays all active sessions in a sidebar with visual alerts for which ones need attention, and simplifies setting up isolated work environments using git worktrees. Built with Python's Textual framework, it reduces the friction of switching between terminals and bootstrapping separate project instances, making it easier to work on multiple coding tasks simultaneously.

I’ve been running parallel Claude Code instances while working on different tasks. Two problems kept slowing me down: 1. I was constantly jumping between terminals to see which session needed input. 2. Using git worktrees added setup friction (installing deps, bootstrapping environments, etc.), which discouraged parallel work. So I built ccmux. It’s a thin layer on top of tmux that: - Adds a glanceable sidebar UI showing all Claude Code sessions - Surfaces attention-needed states with visible alerts - Wraps git worktrees with a lightweight workflow abstraction so spinning up parallel tasks feels cheap Technical details: - tmux provides the pane/session orchestration - The sidebar is built with Python’s Textual (rich TUI) - Each Claude Code session runs as a window in a nested tmux session. I now use it daily to juggle multiple AI coding sessions without losing context. Happy to answer questions or dive into implementation details.
