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 No need to find and install external libraries
Beego is a "batteries included" web framework, which means that a lot of features already come out of the box. This way you don't have to spend time and find third-party libraries to integrate to the framework for most of the tasks you need to complete.
Pro Built-in tool which watches for changes
Beego has a built-in tool which watches the code for changes. This tool (called bee tool) can be configured to run any task once the code changes. It can run tests or reload and rebuild the whole project.
Pro Built in ORM
Beego's eloquent ORM is a simple and fast Object-Relational Mapping which helps with organizing the application's database. Beego examples and documentation all use the beego ORM. No need to learn to use and integrate another ORMs API.
Pro Captcha
Pro Auto testing
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 Very opinionated
Con Very opinionated
Con Non-idiomatic code
Con Builds may fail silently
Sometimes even though a build has failed, the pages will still render. Apparently it caches a previous build when the current one has a problem. This can be a frustrating though because it leaves you wondering why the page you are working on stopped working out of the blue.
