  • Each has a real cost: 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; SolidJS much smaller ecosystem than React, so many problems have no off-the-shelf library
  • Prices and features above were last checked on 29 August 2026.

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

SolidJS

  • Much smaller ecosystem than React, so many problems have no off-the-shelf library
  • The React-like syntax is misleading: components run once, and React habits produce subtle bugs
  • Smaller hiring pool and fewer learning resources than the mainstream frameworks

Answered from the vendors’ own pages

Ruby on Rails: Is Ruby on Rails free?

Yes, Ruby on Rails is free and open-source, licensed under the MIT License. There are no costs associated with using or distributing the framework.

Source
SolidJS: Is SolidJS free?

Yes, open source under the MIT licence.

Ruby on Rails: What is Ruby on Rails licensed under?

Ruby on Rails is licensed under the MIT License, a permissive open-source license that allows commercial and private use.

Source
SolidJS: Is SolidJS just React without the virtual DOM?

The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.

SolidJS: Why is SolidJS fast?

It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.
