Deep Dive: Switching from Uncircle to cmux
Trade-offs, installation & data architecture
What you trade away
cmux is an excellent terminal workspace, but it does not provide Uncircle’s declarative per-project stack, one-click parallel startup, process health view, and automatic restart.
How to deploy cmux
Drag the signed macOS app from its DMG into Applications, or install the Homebrew cask
What it takes to run
macOS only; each coding-agent CLI and its account or API credentials must be installed separately
Where your data lives
Configuration, workspace state, and terminal scrollback live on the Mac; the optional iOS companion connects over the user's local network or Tailscale rather than a vendor relay
Why fork cmux instead of vibe-coding a Uncircle clone?
The core loop · read a yml of processes from the repo, run them, stream logs into terminals, show status dots · is a genuine one-sitting build with node-pty and xterm.js, and mprocs already gives you most of it in a TUI for free. What does not one-shot is everything around it: a native window with tray and notifications, killing whole process trees without orphans on three OSes, crash auto-restart that does not flap, and signed auto-updating builds. And since the paid tier is $19 once rather than a subscription, the usual death-list math barely applies.
