CMUX: Cracking Multitasking with Claude Code
https://cmux.com/
If you use Claude Code, OpenCode, Codex, or other AI coding agents, you’ve probably run into the same problem: once you start multitasking with multiple agent instances, it becomes hard to remember what each one is doing, which one is waiting for input, and which one already finished.
In this video, I show you CMUX, a new open-source Mac app that makes it much easier to manage multiple coding agents at once. It combines a clean terminal experience with workspaces, pane layouts, notifications, status metadata, progress bars, browser integration, and even some lightweight agent orchestration through its CLI.
I’ve been using CMUX for the past few weeks, and it has become one of my favourite tools for working with agentic coding harnesses like Claude Code and OpenCode.
In this video, I cover:
• How CMUX helps manage multiple AI coding agents
• Workspace organization for different projects
• Notifications for completed or blocked agent runs
• Progress bars and status metadata for coding tasks
• Using the CMUX CLI with Claude Code hooks
• Spinning up additional panes and orchestrating agents
• Using the built-in browser for app development workflows
• How to install CMUX on macOS
If you’ve been looking for a better way to multitask with AI coding tools, this may be one of the best developer tools to check out right now.
