there's a big market for "makes your life easier" tools both in B2C and B2B
maybe not that big of a market but who knows
Note, I am deliberately using a generic example, I use Ghostty but I haven't tried Rex yet and I have no idea how much value it provides over competing widgets)
I'd say the whole "lower cost" thing is less of a problem when it comes to ergonomics, we know that many devs buy all kinds of fancy split keyboards and things like that to make their workflow smoother, so I wouldn't be surprised if people easily forked over money to this
question is if it will actually take off or actually provide/slot into workflows that people actually like etc. if it's heavily opinionated or not really innovative, I don't see how people would "move over"
just my take though.
Rex is a more serious challenger to iTerm, for me, but atm has similar flaws (Mac only, for most functionality) without coming close on a feature basis. (Nobody uses all of iTerm's features, but most iTerm fans use a subset of them that still exceeds what less-featureful terminal apps (i.e., all of them) can do).
But libghostty is fuckig amazing. Do you have some internal/personal bespoke app that needs a terminal pane somewhere? Ask your clanker to use libghostty.
Do you have a professional, commercial product that needs a terminal somewhere? Direct your team of highly-paid experienced human software engineers to evaluate libghostty.
It's the fucking business.
