Minion

Minion is Haskell library for developing web applications. It stands between Scotty and Servant

	Scotty	Minion	Servant
As simple as ABC	Yes	No	No
At term level	Yes	Yes	No
Typesafe	No	Yes	Yes
Introspectable	No	Yes	Yes
Generated client	No	No	Yes

Since Minion defines servers at the term level, it's easier to start and without excess verbosity.
