Overview
The Snap framework consists of the following:
- snap-core,[5] a generic Haskell web server API.
- 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 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 (PostgreSQL, MongoDB, etc.), generation of JavaScript from Haskell code, and more.
- 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 input/output (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] Lee Paste's Financial Blog,[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]
