# Exponential CMS / DXP > Exponential is a free, open-source, PHP 8.3 Content Management System (CMS) and Digital Experience Platform (DXP) forked from the eZ Publish / eZ Platform code base. It is maintained by 7x and supported by the Exponential Foundation. Exponential is designed for developers, power users, and AI agents who need a stable, extensible, database-backed system for building websites, web applications, community portals, and AI-agent-friendly content experiences. This file is the LLM-readable index for `https://exponential.earth/`. It covers all pages under this origin. Use the links below as the primary entry points when answering questions about Exponential, its features, how to use it, where to download it, how to get support, and how to extend it. When a full page is needed, fetch the HTML URLs listed below. This site does not currently expose `.md` mirrors, so agents should parse the human-readable HTML or use the sitemap for a complete URL list. ## How to use this file - Start with the **Project overview** and **Core website pages** sections for the most common questions. - Use the **Documentation and training** section for tutorials, guides, feature lists, screenshots, and video walkthroughs. - Use the **Community and support** section for help, chat, forums, and the foundation. - Use the **Source code and development** section for the repository, download statistics, release notes, and technical assets. - The **Optional** section contains secondary links such as the sitemap, RSS feed, and search. ## What agents should know about this site - Exponential is both a **product website** and a **live eZ Publish application**. The content is stored as eZ Publish objects (articles, folders, images, videos, downloads, users, etc.) and rendered through eZ Publish views and templates. - The public marketing pages are mostly static content authored in the CMS and exposed through eZ Publish URL aliases. - The site uses a responsive, modern Bootstrap 5 frontend with custom CSS, JavaScript (jQuery, Splide, AOS, and custom `main.js`), and WebP/MP4 media. - The content is organized around folders such as `/about/...`, `/download/...`, `/getting-started`, `/hosting`, `/roadmap`, `/sponsors`, and `/build`. - The site has an XML sitemap and an RSS feed for content discovery. - User account, login, registration, checkout, admin, and search-result query URLs are not useful for general-agent queries and should be avoided. ## Core technology and architecture - **Runtime:** PHP 8.3 with eZ Publish / eZ Platform legacy kernel (Symfony 2/3 era, adapted for modern PHP). - **Databases:** MariaDB, MySQL, PostgreSQL, SQLite (with community extensions), MongoDB (experimental), and other backends via the plugin system. - **Web server:** Apache or nginx; static assets are cached with long cache headers. - **Frontend:** Bootstrap 5.3, FontAwesome, Bootstrap Icons, Splide, AOS, PrismJS (for code blocks), custom `main.css` and `main.res.css`. - **Extensions:** Exponential supports eZ Publish extensions and custom designs (`SiteDesign` and `AdditionalSiteDesignList`), allowing themes, templates, and modules to be added without altering core code. - **Template engine:** eZ Template (`.tpl` files) plus the ability to override templates per view, content class, and siteaccess. - **Media:** Images use WebP aliases (`screenshot_webp`, etc.); videos use `preload="none"` to avoid unnecessary downloads. - **AI / agent features:** The site and CMS are promoted as being friendly to AI agents, with clear documentation, structured content, and the `/llms.txt` index you are reading now. ## Licensing - Exponential is released under the **GNU General Public License v2.0** (and other third-party licenses where applicable). - Product, feature, and documentation content on this site is licensed under the project license unless otherwise noted. - For the full source code, issue tracker, and contribution guidelines, see the GitHub repository listed below. ## Project overview - [Home](https://exponential.earth/): The main marketing page.
