The site is under maintenance.

Most probably the CPANTS databases are being regenerated from scratch behind the scenes due to the major change in Kwalitee metrics or the update of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.

Ranking

To keep attracting people's attention, CPANTS has been hosting an "online multiplayer game" where you can earn respect by uploading more Kwalitative distributions to CPAN.

As noted everywhere, Kwalitee is not quality. Higher Kwalitee score doesn't mean they are "best" or "good" Perl programmers. They are just good CPANTS game players who diligently improve their distributions as well as their tools for authoring, or maybe who can luckily use better tools from the first. So, don't take these rankings seriously. It's a game after all!
