Key Points:
- Pro features require a valid React on Rails Pro subscription for production use
- Free use is permitted for educational, personal, and non-production purposes
- Modifying MIT-licensed interface files is permitted under MIT terms
- However, using those modifications to access Pro features without a valid license violates the Pro License
License validation mechanisms include but are not limited to:
- Runtime checks for valid Pro subscriptions
- Authentication systems in
react_on_rails/lib/react_on_rails/utils.rband Pro TypeScript modules - The
react_on_rails_pro?method androrProfield generation
While MIT-licensed code may be modified under MIT terms, using such modifications to access Pro features without a valid license violates the React on Rails Pro License.
