Probably Hyper. Don't use it unless you like terminals that crash anytime any program you're running spits out more than a few lines of text too quickly.

Correct, I generally use iTerm. I use Hyper whenever I need a gif/video to present something, since Hyper tends to look fancier and prettier.

Hey, the terminal is Hyper and the theme is spaceship (by Denys Dovhan), you could find it on github here : https://github.com/denysdovhan/spaceship-zsh-theme. It is a theme for oh-my-zsh. There exists a standard oh-my-zsh theme named spaceship too, so don't get confused.

looks like an oh-my-zsh one
