We don't have a comparable ecosystem yet, but IHP uses many popular Haskell libraries under the hood. So many normal Haskell libraries integrate very well, as the underlying data structures are always exposed. Functional programs compose well in general due to it's stateless nature, that helps as well.

IHP also comes with a lot of things you'd typically use external packages for (e.g. Auth).

In general the IHP experience is very different from other Haskell web frameworks and much more batteries included, so a lot of apps typically don't need any external packages at all.
