An interface between Haskell web frameworks and web servers.

Build status

A Haskell web application targets WAI and then can be deployed to any backend with a WAI adaptor. The premier WAI backend is the Warp web server.

WAI also adds modularity and code-sharing through middleware and WAI applications. Code can be written that works with any web framework targeting WAI.
