I think Tabby is a similar project, but personally I spin up and throw out terminals very liberally. Tabby had a horrendous launch time, something more than a second which constantly bothered me while trying to work. I’d love to see how quick this is though!
I tried to use kitty but I have to ssh in to remote machines often for work, usually one of a few hundred edge devices, and I can’t configure them all to work properly with it. Is solid ssh support just not a deal breaker for others?
