Prettier

  • Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
  • Developers must format entire files rather than selective line ranges in some contexts
  • Limited language support compared to some alternatives, though it covers major languages

Ruby on Rails

  • Licensed under the MIT License per rubyonrails.org; as open source software it has no paid tier or vendor price to compare
  • The framework is Ruby-only by design, per rubyonrails.org's own description of its convention over configuration approach, requiring the Ruby runtime rather than supporting alternate languages
