User beware: these claims are not always substantiated, and some of the frameworks in this list are poorly maintained and/or documented.
Since Lisp makes it trivial to do so, you can just grab an HTTP server, HTML generator or HTML template library, a database (see the list of Current recommended libraries) and just write your web application already.
See webframeworkmatrix for a tabular comparison of the various currently available frameworks.
