Warp founder here. We actually are chatting with Mitchell about integrating Ghostty so it's the terminal grid renderer within Warp.

Warp failed to launch. Perhaps too much AI pushed onto the users in the early days that failed to show its charm.

Ghostty remains incredible stable and usable and fast compared to competition.

libghostty makes it pretty easy to do. I spent about two weeks setting something up until it was advanced enough to daily drive. I wanted to have a modal workflow similar to vim or tmux copy mode, but without having the overhead of using tmux... that's probably a lot more complicated than "I want Ghostty but with $X tweak". You can poke around in the repo to get a feel for what's involved if you want: https://github.com/milch/mistty

check out yaw terminal for a terminal first experience that also treats ai cli as a first class citizen. and if you're on windows is very dialed into git bash.
