Where each one falls short

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

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

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
