The scripts typically create tables in a database, install software, adjust permissions, and modify web server configuration files. Although Fantastico is typically associated with open-source software, a handful of scripts are also available which install commercial products, which once installed, are available to all of the domains hosted by a physical server; such as web site builder SohoLaunch, PerlDesk customer support software, and AccountLab Plus software for interacting with Internet registrars. There are more than 50 applications that have Fantastico scripts associated with them, some of these scripts a listed below
