If you're just looking to pimp your terminal and sand off some of the edges, fish is a great shell replacement to try: https://github.com/fish-shell/fish-shell

A lot of Mac users either don't know they're using zsh by default now or simply don't take advantage of it's scripting language/featureset. For those people, I think fish makes a compelling upgrade. No log-in, just a slightly nicer interactive terminal prompt.

Fish is a shell, warp is a terminal emulator. So even if someone uses fish they still need a terminal emulator; e.g. iTerm2 or Terminal.app. Am I missing something?

Warp goes a bit beyond a normal terminal emulator and blurs the line a bit in order to support multiple shells without the user having to configure it in their shell by editing .bashrc or whatever. Eg Clickable position for text entry, which most other text boxes have supported since the 80's. I'm sure there's a readline setting somewhere out there but Warp overrides whatever settings are needed in order to get that to work out of the box.

Wow it looks like it's possible but hard to get readline to take the position from a mouseclick: https://stackoverflow.com/a/55437976

Yep! fish and iTerm2 make a wonderful pair on MacOS, it's my go-to combo. My larger point is that you can add nice features to your terminal without adding cloud logins or shady proprietary clients.

As someone who previously used a very customized zsh, switching to fish was great: reliable, fast, low config, etc

I'm in the same boat. My zsh setup was much fancier, but fish gets me 80% of the features with 0% of the configuration.

Same.

Warp team: I watched the demo and it looks great, and I downloaded it while going through this thread. I didn't install. I think you're boxing yourselves out.
