Not sure if it’s just me, but haven’t been able to get onto the site for awhile.
Caskroom[.]io has not been affiliated with Homebrew or Homebrew Cask since 2016. We don’t know who owns or operates the domain as of 2018.
We don’t recommend you use that site, as we have no control over it.
Homebrew’s (and Homebrew Cask’s) official website is brew.sh. Feel free to use the
brew search command to search for Casks.
