Very curious about your cmux fork, any chance you could link the repo? (Maker of cmux here :))

Totally fair, maker of cmux here. We fixed many RAM usage issues (latest version is 0.64.22), and also added an activity monitor to see how much RAM/CPU coding agents are taking.
My cmux has been running with 136 workspaces and 218 terminals, and has been hovering around 5.7 GB. Granted, the theoretical RAM minimum for this number of terminals is around 1-1.5 GB before real scrollback, so we definitely have more work to do.

Behind the scenes stuff:
https://sf.isopolis.city/dev.html
> The source is Google Photorealistic 3D Tiles. Isometric.nyc explored and rejected the use of 3d building data. It is pretty insane that US gov has free LIDAR data for every city in the US available to the public. I spent <30mins exploring this and stuck to google 3d images. Claude Code whipped up a scraper to stream the 3D Tiles and render with three.js. This gives the best "real" texture base for the model to learn from. Anything else would involve a LOT of manual work to get the inputs right.
> Now that we have the 3D tiles, we need to generate the ground truth pairs for training! Similar to isometric.nyc, I generated a few ghibli-style pixel-art images using Google's Nano Banana. SF terrain is very interesting. There are quite a few distinct features like skyscrapers in FiDi, the hills in the southeast, 2 iconic bridges, lots of coastline, piers, parks, suburban grids and lots of water. I generated a ton of images and curated from them. Getting consistent style was a challenge. There was a LOT of manual trial and error. But as usual, Claude Code added this feature to the dev app that allowed me to select the best images and approve them.

I'm one of the creators of cmux. I'm moving a lot of my own dev work to Mac Minis, so I'm starting to feel quite a lot of the pain you mentioned... will try to make this better!

Can you develop freestyle in freestyle vms?

Could you file an issue with more details: https://github.com/manaflow-ai/cmux/issues
Would greatly appreciate it!

Should be fixed in latest release (0.58.0). Please let me know if it's still an issue!

Thanks for the feedback! Mitchell Hashimoto is awesome. Have a PR for fixing devtools here: https://github.com/manaflow-ai/cmux/pull/117
> hotkey overrides - I have some things explicitly unmapped / remapped in my ghostty config that conflict with some cmux keybindings and weren't respected
We need to be better about this; right now you can modify keyboard shorcuts with cmd+, in the GUI. Planning on making it a config file in the spirit of ghostty though, not sure if we want to reuse ghostty's config file though since it might become a maintenance burden for them...
> command palette (cmd-shift-p) for less-often-used actions + discoverability
yes
> cmd-z to "zoom in" to a pane is enormously useful imo
Thinking of the right way to design this. Like hypothetically we can expand it, but what happens if you make a vertical/horizontal split, or cmd+t to make a new tab? I guess we could just "merge" it back into the original space which would be pretty cool.

We're working on a tmux/it2 compatibility layer to make this happen!

No built in way to override new-pane actions right now, but `cmux --help` can automate all parts of cmux.
So you can make your own script that can make new panels/workspaces and just invoke it from the terminal:
git worktree add -b my-branch ../repo-my-branch
ws=$(cmux new-workspace 2>&1 | awk '{print $2}')
cmux send --workspace "$ws" "cd ../repo-my-branch && claude"
cmux send-key --workspace "$ws" Enter
