Where each one falls short

Bolt.new

  • The free plan is capped at 300K tokens a day and 1M tokens a month
  • Pro starts at 10M tokens a month for $25, so heavy sessions are metered rather than unlimited
  • Team seats are billed at $30 per member per month and tokens are not pooled across the team
  • Unused tokens roll over for one additional month only, so they expire after two

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
