Spring vs Symfony: What are the differences?
Developers describe Spring as "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. On the other hand, Symfony is detailed as "A PHP full-stack web framework". Symfony is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP. Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
Spring and Symfony belong to "Frameworks (Full Stack)" category of the tech stack.
"Java", "Open source" and "Great community" are the key factors why developers consider Spring; whereas "Open source", "Php" and "Community" are the primary reasons why Symfony is favored.
Spring and Symfony are both open source tools. It seems that Spring with 30.1K GitHub stars and 19.2K forks on GitHub has more adoption than Symfony with 21K GitHub stars and 6.98K GitHub forks.
According to the StackShare community, Symfony has a broader approval, being mentioned in 355 company stacks & 267 developers stacks; compared to Spring, which is listed in 316 company stacks and 179 developer stacks.
