Sites, Applications, and Systems that are Powered By Tomcat
This page is a list of some, in all likelihood a very small fraction actually, of the sites out there that use [http://tomcat.apache.org Apache Tomcat] in production. For security and other policy-related reasons, many organizations choose not to disclose the server they use. Tomcat has been downloaded more than 1 million times: assuming even a 1% production adoption rate results in more than 10000 installations. (By the way, you can see recent Tomcat download statistics on [http://people.apache.org/~vgritsenko/stats/projects/tomcat.html Vadim Gritsenko's page]). Companies that support Tomcat, such as [http://www.covalent.com Covalent] claim more than half of the global Fortune 500 as their clients.
This page is organized by categories: [#pub sites with publications], [#user sites added by users], [#surveys independent surveys], and [#more more]. Anyone can and is encouraged to add to this page: please add your site, application, or system as you see fit. You do need to register with the Apache wiki system to edit this page: simply click the login or user preferences links at the top right of your screen to do so. Don't worry if you don't think it fits here or into any particular category: we would like to see your application listed no matter how big, how small, or how miscategorized 
Some of these applications are simply compatible with, ship with, or run on Tomcat. Others are specifically designed or documented with Tomcat as the container in mind.
Please note that all the corporate logos and names used below are trademarked by their respective organizations. These organizations are not affiliated with this web site or with The Apache Software Foundation, and make no claims regarding The Foundation or its products. Further, in most cases the companies are not aware of their being listed on this site at all.
