I suspect Ghostty is to Rex what Chromium is to Google Chrome (without all the negative connotations that is, I’m a happy Rex user!): both something of a tech demo for libghostty, and an open source, basic-but-fully-featured terminal emulator. Rex, then, will possibly be a paid product at some point, and adds features like the server, agent integration, and persistent session management on top. If you had asked me two years ago if I was ready to pay for my terminal and quit my jetbrains subscription, I’d have laughed. Now I’m earnestly ready for that if Superlogical were to announce a paid plan.
