I've made a terminal that is essentially ghostty + herder, but all natively and has a session persistence. https://thurm.rs
there is an ios application in testflight and web client, nothing is on the servers, using tailscale through clients or you can use classic remote hosts.
p.s. it has a daemon and automatically installs claude/codex/pi skills so the agent knows how to control and script the panes, tabs and everything else. It is also heavily inspired by Rex's design.
I just hard forked paseo and used its websockets/relay system w/e2ee along with some additional credentialling.
Seems like we all get tailored suits now.
hehe, I also have done the same, but I'm building on top of tmux. Though much more minimal in scope. https://kido.tools (website showcases the TUI only but there's native macOS app in the PR which I'm using but still refining).
We should compare notes!
