Haskell web framework inspired by Ruby's Sinatra, using WAI and Warp (Official Repository)

A Haskell web framework inspired by Ruby's Sinatra, using WAI and Warp.

Scotty is the cheap and cheerful way to write RESTful, declarative web applications.

  • A page is as simple as defining the verb, url pattern, and Text content.
  • It is template-language agnostic. Anything that returns a Text value will do.
  • Conforms to WAI Application interface.
  • Uses very fast Warp webserver by default.
