happstack-server

happstack-server contains a low-level HTTP backend, and high-level functions for routing requests, examining request data, and generating responses. happstack-server is part of the Happstack framework, but can be used as an independent entity. The low and high level portions of the server are not cleanly separated into different packages, so it is not the best choice if you only need a low-level backend.

Snap Server

Part of the Snap framework, the Snap server is similar to Hyena in that it provides a very fast low level web server. From the Hackage package:

This is the first developer prerelease of the Snap framework. Snap is a simple and fast web development framework and server written in Haskell. For more information or to download the latest version, you can visit the Snap project website at http://snapframework.com/.

The Snap HTTP server is a high performance, epoll-enabled, iteratee-based web server library written in Haskell. Together with the snap-core library upon which it depends, it provides a clean and efficient Haskell programming interface to the HTTP protocol.

Higher-level facilities for building web applications (like user/session management, component interfaces, data modeling, etc.) are planned but not yet implemented, so this release will mostly be of interest for those who:

  • need a fast and minimal HTTP API at roughly the same level of abstraction as Java servlets, or
  • are interested in contributing to the Snap Framework project.
