Where each one falls short

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

Carrd

  • Free tier strictly limited to 3 sites; any additional sites require upgrading to Pro
  • Pro plan includes Carrd branding removal but still lacks advanced features (e-commerce, multi-step funnels, complex forms)
  • Single-page design only; does not support multi-page websites or complex site structures
  • Limited template library compared to competitors like Leadpages or Unbounce
  • Annual payment required for Pro tier; no monthly payment option
  • No native A/B testing, analytics dashboard or conversion optimisation tools built-in

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
