I'm the author of Zazu, I'm happy to answer any questions. Ask away!
But, they recently made that unavailable for download and want me to buy v3... Which I don't need.
So I've been awaiting an alternative.
So thanks for this ! I'm excited to try it out.

P.S.: not sure about license compatibility of v1 -> v2.
This looks great. I've been debating on building my own tool for this. I'll try and contribute some code to this.
Technically it spins up another process and recursively goes through a whitelisted set of directories. It caches just the app locations, not all the files.
brew cask install zazu
should work to install via Homebrew, but it doesn't. $ brew update && brew cask install zazu
Works for me... $ brew --version
