IHP is already used in production for a number of commercial projects, but I'd also highly recommend the framework for anyone interested in just learning and hacking away with haskell. The IHP IDE is a great playground and you are automatically set up with a postgres db, ghc, hls, etc. So a lot of the configuration barrier is removed and you can just start writing Haskell and experimenting with some of the cool libraries on hackage.
