Symfony vs Yesod: What are the differences?
What is Symfony? 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.
What is Yesod? A RESTful Haskell web framework built on WAI. Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference.
Symfony and Yesod can be categorized as "Frameworks (Full Stack)" tools.
"Open source" is the primary reason why developers consider Symfony over the competitors, whereas "Haskell" was stated as the key factor in picking Yesod.
Symfony and Yesod are both open source tools. It seems that Symfony with 21.1K GitHub stars and 7.01K forks on GitHub has more adoption than Yesod with 2.11K GitHub stars and 329 GitHub forks.
According to the StackShare community, Symfony has a broader approval, being mentioned in 374 company stacks & 277 developers stacks; compared to Yesod, which is listed in 5 company stacks and 5 developer stacks.
