Specs
Question Ranking
Pros
Pro Offers templating for type-safe, well-formed content
While not required, Yesod offers templating through a Shakespearean family of languages to produce page code.
Pro Uses type-safe URLs
Ensures that data provided by the URL is type-safe. This means that data in the URL has a definitive type.
Pro Can be used without knowing much Haskell
While Yesod is written in Haskell, developers can achieve basic functionality without much investment in the language.
Pro Backed by a major corporation
Hapi was developed and is still being used by Walmart. Being backed by such a major company means that it will not lose support any time soon and most importantly it's being developed by professionals and that you will always get support for it.
Pro Consistency across applications
Hapi's philosophy is that configuration is more important than code. This is especially useful for very large teams because it helps developers maintain consistency and reusability throughout their code.
Cons
Con Is hard to customize
Learning how Yesod works internally is hard. It is a large framework with complicated components. Finding the appropriate code and understanding how it contributes to the framework is difficult, meaning developers will struggle.
Con Too much template haskell
You actually want to code in haskell and not some DSL with "magic" hidden under the bonnet.
Con Requires too much boilerplate
Hapi seems to be made with large applications in mind. The sheer amount of boilerplate code it requires is simply not practical for a small web app. This also means that there are few examples of Hapi applications around for beginners to learn from.
