There are options for using Sass in a project without having to work on the command line.
Koala is a GUI app that compiles Less, Sass, CoffeeScript and more automatically in the background. Free. (I'm recommending this one.)
Codekit does everything for you in terms of pulling your Sass, Javascript, Templates and so on together for a working site. It is macOS only. $39.
Another do-it-all tool modeled after Codekit, but available on all three OSes: macOS, Windows, and Linux. $29
Not an alternative, a list of alternative ways to build websites. My personal preference is Jekyll, but there a many others.
