snap-server,[6] a fast[7] HTTP server that implements the snap-core interface.
Heist,[8] an HTML-based templating system for generating pages that allows you to bind Haskell functionality to HTML tags for a clean separation of view and backend code, much like
Lift's snippets. Heist is completely self-contained and can be used independently.
Snaplets,[9] a high-level system for building modular web applications.
Built-in snaplets for templating, session management, and authentication.
Third party snaplets for features including file uploads, database connectivity (

The Snap
monad for stateful access to HTTP requests and responses.[10]
Snap runs on both Windows NT and Unix-like platforms. Snap uses the
Iteratee I/O model,[11] As of version 1.0, its i/o is implemented with
io-streams.
Usage
Snap is used by Silk,[12] JanRain,[13][14] Racemetric,[15] www.lpaste.net,[16][17] SooStone Inc, and Group Commerce. Snap is also used as a lightweight, standalone Haskell server. The static site generator Hakyll uses Snap for its preview mode.[18]
