Implementations of the Web Server Gateway Interface

Note: many of these implementations may be partial/incomplete or noncompliant as of the current draft spec. If you can't get the code samples in the spec to work with one of these implementations, there's a good chance that the implementation is broken: contact the implementation's author.

See [http://www.python.org/peps/pep-0333.html PEP 333] for more information on WSGI.

Web Server implementations

• [http://mail.python.org/pipermail/web-sig/2004-October/000956.html wsgiref] - a library of base classes covering most of the "hard parts" of a WSGI server implementation, written by the PEP author. It also includes utility functions and classes that may be useful for application/framework implementors, and should be considered a "must read" for server implementors. (Update: most of the limitations mentioned in the linked post have now been resolved; wsgiref now includes sensible default error handling and logging, automatic calculation of Content-Length when possible, and greater test coverage.)

• [http://www.xhaus.com/modjy modjy] - a WSGI implementation for Jython

• see Jonpy below
• see WSGIUtils below

• [http://st0rm.hopto.org/wsgi/ Twisted] (If the server isn't working, there's a copy [http://svn.colorstudy.com/trunk/WSGIKit/wsgikit/twisted_wsgi.py here])

• [http://www.idyll.org/~t/www-tools/wsgi/] - SWAP, a WSGI adapter for [http://www.mems-exchange.org/software/scgi/ SCGI].

• [http://pyds.muensterland.org/wiki/toolserver.html Toolserver Framework for Python] - a WSGI implementation in a Medusa-based webservice framework

• [http://isapi_wsgi.python-hosting.com isapi_wsgi] - a WSGI implementation for IIS ISAPI

Web Framework implementations

• [http://www.pythonweb.org Python Web Modules] - New version contains a WSGI server and middleware.

• [http://svn.colorstudy.com/trunk/WSGIKit WSGIKit] - a [http://w4py.org Webware] reimplementation, implemented with a degree of framework-neutrality in mind.

• [http://st0rm.hopto.org/wsgi/ Jonpy] - this also includes a HTTP server with a WSGI backend

• Nevow - in a branch of its Subversion repository. (Can someone supply a link to this?)

• [http://www.owlfish.com/software/wsgiutils/ WSGIUtils] - A multi-threaded WSGI server implementation and a simple framework providing basic user authentication, signed cookies, and persistent sessions.

• [http://www.idyll.org/~t/www-tools/wsgi/] - QWIP, a WSGI adapter for [http://quixote.ca/ Quixote] applications.

• [http://subway.python-hosting.com Subway] - early work on a [http://rubyonrails.org Rails]-like system.
