Description
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.

Could you build this?
Yes A multiplexer CLI or wrapper script to switch between terminal tabs/windows running parallel CLI instances can be assembled in an afternoon using tmux or terminal UI libraries.
Discussion
5 comments analyzed.
Concerns raised: Setup and teardown of worktrees too cumbersome without ccmux, Lightweight context (name + branch) insufficient for long-running multi-day sessions
Feature requests: Auto-generate and maintain session summaries with AI (like git commits), Search feature to find and resurrect old Claude code sessions, Enhanced context/metadata beyond name and git branch for task tracking

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
