There's also skim[1], which would be a Rust fzy alternative.
But neither fzy nor skim quite do what fzf does, which is offer an simple feature-filled experience out of the box. The big draw is fzf Just Works™. I don't mind that it feels bloated and slow sometimes, because I don't want to spend a week figuring out how to make the other two do what fzf does without configuration or drama, and all the speed improvements in the world doesn't really matter when the bottleneck is the meatball behind the keyboard.
