Its principles, such as Convention Over Configuration and modularity through gems, have inspired a generation of frameworks like Laravel and Django, emphasizing developer productivity and experience. As Rails continues to evolve, it sets a standard for open-source projects and maintains relevance in modern web development.

AmazingPrint is a Ruby library that enhances the pretty-printing of Ruby objects with full color and proper indentation, making it a suitable replacement for the now-stale AwesomePrint.

Tips for integrating `dbg-rb` into Rails without adding it to the Gemfile are also discussed.
