Rails vs Spring: What are the differences?
What is Rails? Web development that doesn't hurt. Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.
What is Spring? Provides a comprehensive programming and configuration model for modern Java-based enterprise applications. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
Rails and Spring can be categorized as "Frameworks (Full Stack)" tools.
"Rapid development", "Great gems" and "Great community" are the key factors why developers consider Rails; whereas "Java", "Open source" and "Great community" are the primary reasons why Spring is favored.
Rails and Spring are both open source tools. It seems that Rails with 43.6K GitHub stars and 17.5K forks on GitHub has more adoption than Spring with 30.6K GitHub stars and 19.6K GitHub forks.
Airbnb, Twitter, and Instacart are some of the popular companies that use Rails, whereas Spring is used by MIT, Zillow, and Intuit. Rails has a broader approval, being mentioned in 2321 company stacks & 796 developers stacks; compared to Spring, which is listed in 319 company stacks and 184 developer stacks.
