Applications and libraries
Applications, libraries and tools written in Haskell.
Developers: if you release any Haskell code, please document it for the community, by adding it to the appropriate category on this page.
The first places to look for data types or functions are:
- The Standard Prelude
- Language and library specification
- The Standard Hierarchical Libraries
- Hoogle - The Haskell API Search Engine
- The Hackage database
HackageDB is the new central database for 3rd party Haskell packages. Look here for stable versions of common libraries. Developers: upload your cabalised packages to hackageDB (if you don't have a login, just ask). Recent packages uploaded to HackageDB.

Guidelines for developers
- How to write a new Haskell library
- Creating a .deb from a Haskell Cabal package
- Creating a Haskell library by example
- Guide to making standard library submissions
- If you notice the library documentation is lacking, or could be improved, please report it here
- Google Code Search can help identify common idioms, improving your API
- Wanted libraries: if you can't find a library for a problem, document it here, and someone might write it.
- Project activity for some of the larger Haskell projects is graphed here.
- Cabal, The Common Architecture for Building Applications and Libraries, is a framework for packaging, building, and installing any tool developed in the Haskell language.
Proposals for the module name space layout that can be used to guide the construction of new libraries.
Libraries for other languages
If you are thinking about designing a new library for Haskell, you ought to look what has been done in other languages. Here are standard library definitions for
