Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Docusaurus
- Customisation past the config file assumes React knowledge, which not every docs team has
- Build times grow noticeably on very large sites, particularly with many versions and locales
- Major version upgrades have required real migration work rather than a dependency bump
- It generates a static site, so anything dynamic — gated content, per-user docs — needs a separate solution
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
