I'm all for opening up the code. I will link up a download once I've cleaned up the documentation for the cgi's.
However, if you want to run it locally, you might as well just use the 'perltidy' and 'perlcritic' command line utilities that come with their respective cpan modules instead of calling out to a web service if you're going to run it locally.
I do understand potential privacy concerns that people may have in using my webservice (though I assure you I'm not logging any code submitted) and so I could see that having an private 'perl tools' web service machine running these scripts would be preferable for some (or many?).
