HAppS (Haskell Application Server) is a Free application server for websites written in the functional programming language Haskell. It integrates handling Web, persistence, email (sending and receiving), DNS, XML/XSLT, Amazon S3 backend, and database server functionality. It makes use of a number of Haskell libraries and systems such as Parsec, Cabal, Template Haskell, and monad transformers ("Your app then is just a set of state transformer functions (in the MACID Monad) that take an event and state as input and that evaluate to a new state, a response, and a (possibly null) set of sideeffects.") among others. HAppS has been abandoned and a new version is being maintained Happstack. less
