Introduction

Running Claude Code in multiple parallel sessions has become the norm. Along with this, various session management tools have emerged.

However, before choosing a tool, the first thing to understand is that these tools generally fall into two approaches. Understanding this will naturally narrow down which tool is right for you.

Two Approaches

Worktree Management Type

Examples: claude-squad, vibe-kanban, workmux, dmux

These tools assume a workflow of "new task = new worktree + new session" and manage everything from session creation to worktree isolation, merging, and cleanup in an integrated manner.

Pros

  • Since branches are automatically isolated for each task, conflicts during parallel work are less likely to occur.
  • You can leave the session lifecycle management (creation, monitoring, termination, merging) to the tool.
  • Because you only need to follow the tool's instructions, the hurdle for multi-session operation is low.

Cons

  • Since the tool takes control of the entire session lifecycle, the workflow becomes tool-centric.
  • It is difficult to leverage existing tmux sessions or pane configurations.
  • Merging and cleaning up worktrees also go through the tool, which may conflict with your existing Git practices.

Existing Environment Monitoring Type

Examples: crmux, cmux, TmuxCC

This approach detects and monitors sessions that are already running. You are free to decide how to create sessions and how to manage Git.

Pros

  • Can be introduced without changing your existing workflow.
  • tmux pane configurations, vim settings, and integration with other CLI tools can be used as they are.
  • Since it only "looks into" the sessions, it does not disrupt the state of other panes.

Cons

  • You need to perform worktree isolation and merging yourself.
  • Session management automation is limited, and a certain level of tmux literacy is assumed.

Why I Chose the Existing Environment Monitoring Type

Since I am the creator of crmux, this part is biased. However, my reason for choosing this approach is clear.

I did not want to let go of my tmux-centric workflow.

My development environment is composed of tmux sessions, windows, and panes. I run NeoVim within them, and I use various CLI/TUI tools in combination within tmux. I run multiple instances of Claude Code in parallel as one of those panes. Recently, I've had about 10 running.

Using a worktree management tool would require me to adapt this configuration to the tool. I would be delegating the session lifecycle to the tool, and my local pane configuration would become "something managed by the tool." That didn't fit my needs.

crmux does not change existing panes; it just looks at them. You can send text via tmux's send-keys only when necessary. There is peace of mind in knowing it won't break the state of other panes. This was important to me. (I can always return to the pane where Claude Code is actually running.)

Of course, I have to handle worktree isolation myself, but since I'm the type who prefers to manage my Git operations, this is actually more convenient.

Conclusion

I don't think one approach is better or worse; it's about choosing based on whether it fits your workflow.

  • If you want to aggressively run parallel tasks based on worktrees, the Worktree Management type is easier.
  • If you don't want to disrupt your existing tmux environment, the Existing Environment Monitoring type is a better fit.

All of these tools are being actively developed, so I recommend trying out the ones that interest you.

Personally, if an official "definitive" tool is released, I might end up switching to it.
