 As you can see, there is quite an above-average offer of them. They mostly differ at the level of abstraction and scope: Scotty being relatively low-abstraction routing and middleware and Yesod being a complete solution including templating and persistence, everything on a high abstraction level. The choice depends on your preference and needs. As always, a higher abstraction means the system does a lot of job for yourself, you write fewer code, which means a higher effectiveness and less bugs. On the other hand, you may face a [leaky abstraction problem](https://blog.codinghorror.com/all-abstractions-are-failed-abstractions/) at some point.

+### IHP (Integrated Haskell Platform)
+
+[IHP](https://ihp.digitallyinduced.com/) is a batteries-included web framework for Haskell. It is designed to be easy to use and to provide a lot of functionality out of the box, including:
+
+* A powerful type system that helps catch errors at compile time
+* A built-in ORM (Object-Relational Mapping) for working with databases
+* A templating engine for generating HTML
+* A development server for testing and debugging
+
+IHP is a good choice for developers who want to build web applications quickly and easily, without having to worry about the underlying details of web development. It is also a good choice for developers who want to take advantage of Haskell's powerful type system and functional programming features.
+
+The architecture of IHP is based on the Model-View-Controller (MVC) pattern, which helps to keep the code organized and maintainable. The framework also provides a lot of built-in functionality for common web development tasks, such as authentication, authorization, and database migrations.

 ### Scotty
 
 [Scotty](https://github.com/scotty-web/scotty) is another Haskell web framework inspired by Ruby's [Sinatra](http://sinatrarb.com), using [WAI](https://hackage.haskell.org/package/wai) and [Warp](https://hackage.haskell.org/package/warp) (a fast, light-weight web server for WAI applications). You can write your own application just with WAI (Web Application Interface), but Scotty provides you with abstractions from a low-level communication. Sadly, there is not so much documentation about Scotty, everything is just on [GitHub](https://github.com/scotty-web/scotty). Scotty uses primarily [Blaze HTML](https://hackage.haskell.org/package/blaze-html) for HTML "templates", however, as we explained, you may also integrate it with any templating library you like.
