Sitetheory is a robust and scalable framework to build beautiful and highly functional platforms. It is built to empower vendors, developers and design partners to rapidly create cool websites and powerful mobile apps. Sitetheory is the first vendor among many, with an admin website that functions as a website builder, CMS (Content Management System) and CRM (Customer Relationship Management). But other vendors can leverage the existing UI, API, Content Types, and Functionality to create their own identical (white labeled) or distinct platforms or just to make individual websites.

On the backend, Sitetheory utilizes Symfony as a modern framework, Doctrine for database and entity management, and Twig for HTML templating. As a CMS framework, Sitetheory just manages page requests on the server side. The current URL determines the correct Content (page) to load. Each Content is associated with a specific Content Type, e.g. Article, Profile, Landing Page Stream, etc. Sitetheory will load the correct Controller for the current Content Type, as well as the appropriate Twig Template. Individual Themes or websites can extend or overwrite the Controller or Templates to allow for endless customization.
