Where each one falls short

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

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

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits
