Ask HN: Homebrew Cask for Linux?

What do you use to provision your Linux machine with pre-built (GUI) binaries that are not available via your distribution's package manager (apt, rpm etc.) I'm thinking about applications like Atom, PyCharm, Google Chrome, Skype, Spotify, etc.

The closest equivalent to Homebrew Cask I've found is Linuxbrew Binary [1] for the Linuxbrew fork [2]

Is there any other package manager / solution I'm not aware of?
