The document describes different frameworks used for ISUCON including Sinatra, Kossy, and Express for Ruby, Perl, and Node.js respectively. It then shows an example Python application built with Flask that defines routes for index and post endpoints, renders templates, and is deployed on Apache with mod_wsgi. The Flask app code is available on GitHub from the user memememomo.
