Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bootstrap

  • Default styling is recognisable, so sites can look generic without deliberate customisation
  • Ships a large stylesheet, and unused CSS must be purged to keep payloads reasonable
  • Component-based approach fits less naturally into React and Vue codebases than libraries designed for them

Sass

  • Licensed under the MIT License per sass-lang.com; as open source software it has no paid tier or vendor price to compare
  • The LibSass and Ruby Sass implementations are marked deprecated on sass-lang.com, leaving Dart Sass as the only actively maintained compiler
