The short version
- Each has a real cost: Spring Boot requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported; 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

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Spring Boot
- Requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
- Requires Spring Framework 7.0.8 or above and Gradle 8.14+ or Maven 3.6.3+, per Spring's own system requirements page, so older toolchains must be upgraded first
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
