ClaudeTTY: The Undying cmux When cmux or other terminals crashed, it used to just be another day. but when Claude's in the middle of a command that could ruin my computer if it goes wrong, it's a bit worrying and jarring. In ClaudeTTY tabs live in zmx sessions outside the app, so quitting, crashing or updating it doesn't kill anything. Tabs and groups don't die unless you explicitly quit them. It also has better tools for keeping an eye on your Claude sessions. each tab's dots show if its Claude is thinking, writing, reading or running code, and they turn amber when it's waiting on you. Clicking "3 agents" opens a subagent's transcript live beside its Claude. I built it with Claude Code on libghostty, about 4,800 lines of Swift in three files. If you want it different, have Claude change it and run ./install.sh, and the open window switches to the new build without killing anything. Free, macOS 26 on Apple Silicon. aqilc/ClaudeTTY

I made an undying cmux I used cmux for a while and loved the layout, but it crashed a lot for me and updates killed everything I had running, which slightly hurts when Claude's running something about to brick my computer if it stops. In ClaudeTTY, tabs live in zmx sessions outside the app, so quitting, crashing or updating it doesn't kill anything. Tabs and groups don't die unless you explicitly quit them. It keeps cmux's layout and shortcuts, and it tracks each Claude instead of each workspace, so with 4 Claudes in a group you can see which one's thinking and which one's waiting on you. You get one notification per tab and it clears when you look at that tab. I left out the browser and file viewer since I never opened them. It's a lot lighter too, 68 MB vs 1,029 MB for cmux on my M4 Pro with one idle tab. Also, just for fun, terminal-browser runs better in ClaudeTTY than in cmux. cmux is what got me working this way, so credit to the devs. Free, macOS 26 on Apple Silicon. aqilc/ClaudeTTY

I know this is hard for security and dozens of reasons, but the thing that drives me nuts about mosh is not having SSH's ControlMaster protocol so I can multiplex. It's a protocol thing, so not directly fixable via a compatible implementation. But it just sucks, I have so many tabs, and I have each one having to do the deed again, maintain it's own connection. I chatted with Astra about this ask here: chatgpt.com I flip on and off using my own term-preserver toolkit, which let's me autoreconnect to servers (via ssh) and or tmux sessions automatically. tangled.org .
