Show HN: Boo – Screen-style terminal multiplexer built on libghostty

Slightly off-topic:I currently use tmux. Not because I need to multiplex shells in a remote server, but because I like to have my sessions persisted in my local machine. Even between reboots (technically not the same session, but the same tabs and splits I had). I currently have that with tmux and a tmux plugin that restores my sessions. But I think that tmux is overkill for this. And if I'm in a tmux session, then I can't use my terminal emulator's native tabs and splits. Does anyone have a recommendation of how to handle only terminal sessions on Linux?

How would this compare to shpool: https://github.com/shell-pool/shpool

Interesting choice building on libghostty —
how does it handle session persistence across reconnects?

This is super cool. I've been a heavy tmux user for a long time and using it more with my coding agent sessions and prefer ghostty. What was the biggest challenge when it came to building a multiplexer directly on top of libghostty that you ran into?

Been using zmx for a few months and love it: https://github.com/neurosnap/zmx/Very similar, based on libghostty

Really dig the minimal approach here. Swapping the backend to libghostty is exactly the kind of clean architecture we need. Going to test drive this today.

I think Cmux is the incumbent in the "screen-style terminal multiplexer built on libghostty" - any key differentiators here? https://cmux.com/

Installed using the curl-to-bash on Sequoia and I’m getting “error: ReadOnlyFileSystem” on ‘boo new’. Can’t see any open issues on gh and nothing in the readme.Definitely interested in something like this - love ghostty and I’ve been finding Zellij a bit crashy recently (plus I don’t really need tabs).

this looks nice! i've been using herdr the last couple of weeks as a terminal multiplexer for agents, which works amazingly well.

You've obviously written this because screen wasn't doing the right thing, but your readme only explains that it's a "young project, not a drop-in GNU screen replacement". What are its advantages over screen or tmux?
