Doesn’t work as insanely quickly as voidtools’ Everything, but I use Thomas Tempelmann’s Find Any File as my Everything replacement on macOS:

I love how you remember the authors of the tools you use.

Alfred does use its own index, instead of Spotlight’s, so it is certainly miles faster than macOS’s built in search; make sure to check what directories are being searched over in settings.
