Your terminals, remembered.
A macOS app for people who live in Claude Code, Codex and tmux. Every agent session on your Mac and every tmux session on your servers stays one click away, in a grid or in tabs, and comes back after a restart.
Download for macOSA grid of sessions
Nine terminals on one screen, each its own session, in a smaller font so they fit. Expand one to the whole window when you need to read it, and put it back. Prefer tabs? One switch.
Nothing gets lost
Claude Code and Codex conversations resume exactly where they stopped. tmux sessions reattach when Megamux starts. Closing an agent or a tmux session never ends it: tmux detaches, and a local agent keeps working in the background.
tmux on your servers, without typing tmux
Add a host you reach over SSH and Megamux lists its tmux sessions and what runs in each. Attach, rename, detach or kill one with a click.
Knows when an agent needs you
A session that finishes, waits for your input or rings the bell gets a NEW tag, a count on the Dock icon and a short ping, while you work somewhere else.
Install
- Download the DMG above, open it, and drag Megamux into Applications.
- Open Megamux from Applications. It is signed and notarized by Apple, so it opens without warnings.
- From then on Megamux updates itself: it checks once at launch and asks before it restarts. Settings › Updates shows your version and checks on demand.
