title: Command-Line Interface
introduction: >
  Different implementations of Sass have different interfaces when using them
  from the command line:
---

- [Dart Sass](/documentation/cli/dart-sass) has the same command-line interface
  no matter how you [install it](/dart-sass).

- [Ruby Sass](/documentation/cli/ruby-sass) is [deprecated](/ruby-sass), and we
  recommend you move to a different implementation.
