Every project, every agent.
One window.

Cmux Pro is a centralised place for all of your work, with every project in its own workspace, colour-coded by how recently you used it.

Stay in a workspace and it turns green, then fades to amber, red, quiet.

Group your work however you think

Drag workspaces into groups for clients or products, each with its own colour.

Close it, reopen it, nothing moved

Everything comes back where you left it. The colours pick up where they stopped.

How to best use it

Set it up as a system

  1. 01
    Keep one master folder for all of it. Every group and workspace lives inside a single folder on your Mac, so your whole setup stays in one place.
  2. 02
    Organise workspaces that belong together into groups. A group gathers related workspaces under one heading, so Health keeps workouts, dental, health-app and bloodwork-analysis together instead of scattered.
  3. 03
    A workspace is one project. Each one keeps its own folder, session and history, so you pick up exactly where you left it.
  4. 04
    Split your projects into separate workspaces. Everything in a workspace becomes context the agent has to carry, so keeping one project per workspace stops it juggling your workouts, your dental notes and your app codebase at the same time.
  5. 05
    Use colours for groups and workspaces. Give a group its colour and its workspaces carry it, so you can tell which part of your work you are looking at without reading a single name.
  6. 06
    Use the activity system. A workspace turns green while you work in it and cools as you leave, so you can see which are live and which have gone quiet. Set the timings in Settings.
  7. 07
    Use the mini-apps to supercharge your workflow. Review changes, watch progress, check what Claude remembers and edit files from the tab bar, so checking the work never costs you the window.

Only the first time. It opens normally after that.

Open a project

Start a session and stay in it. The workspace turns green and moves to the top.
