Sass is a mature CSS preprocessor language that extends CSS with variables, nested rules, mixins, functions, and selector inheritance, compiled to standard CSS. The sass/sass repository hosts the language specification and proposals, with the primary implementation being Dart Sass, distributed as a standalone CLI, a Dart library, and the pure-JavaScript sass / sass-embedded npm packages.

Use cases

  • compile scss to css
  • use variables and mixins in stylesheets
  • organize large css codebases with nesting and partials
  • integrate sass compilation into a webpack or vite build
  • programmatically compile sass from node.js or dart
  • share design tokens across projects with sass functions

When to choose

  • you want a battle-tested, fully-featured CSS preprocessor with active development
  • you need a fast standalone CLI or embeddable JS/Dart API for compiling stylesheets
  • your project already uses .scss/.sass files and needs the reference implementation

When to avoid

  • you only need plain modern CSS, since native CSS now supports variables and nesting
  • you rely on LibSass or node-sass, which are deprecated and no longer receive new features
  • you want a utility-first or component-scoped styling approach rather than a preprocessor
